Your pathologists never meet the patient, never collect insurance cards and never have a check-in desk. Instead, demographics, diagnosis codes and authorization details arrive secondhand on a requisition, often incomplete.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">That structure changes everything about billing. Generic <strong><a href=\"https:\/\/www.medicalbillersandcoders.com\/medical-billing-services.aspx\">medical billing services<\/a><\/strong> were designed around E\/M visits, where the front desk can fix eligibility before the encounter. Pathology billing services have to repair data after the fact, at scale, without a patient touchpoint.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">In addition, coding is unusually technical. Surgical pathology runs from 88300 through 88309 based on specimen complexity, and choosing 88305 when documentation supports 88307 quietly reduces reimbursement on every case. Immunohistochemistry requires 88342 for the first single-antibody stain and 88341 for each additional one per specimen, and a miscount repeats across the whole caseload.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Next come component rules. A pathologist reading slides for a hospital bills the professional component with modifier -26, while the hospital or reference lab owns the technical component. Labs that perform both bill globally. Getting that split wrong either leaves money unbilled or invites recoupment.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">This is why lab groups increasingly treat pathology billing services as a specialty discipline, not a commodity task. The partner you choose needs coders who know anatomic, clinical and molecular coding, and workflows built for requisition-driven data.<\/p>\r\n\r\n\r\n\r\n<h2 id=\"h-the-financial-pressure-on-pathology-labs-and-groups\" class=\"wp-block-heading\">The Financial Pressure on Pathology Labs and Groups<\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Pathology margins are thin per unit and large in aggregate. A single 88305 claim is modest, but a group processing six figures of specimens per 12 months depends on near-perfect accuracy to protect net realized revenue.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Specifically, Medicare sets clinical lab payment through the Clinical Laboratory Fee Schedule (CLFS), which the Protecting Access to Medicare Act (PAMA) tied to private payer rates reported by labs. CMS publishes current CLFS files on its Clinical Laboratory Fee Schedule page. Anatomic pathology professional services, by contrast, are paid under the Physician Fee Schedule. Consequently, two schedules mean two sets of rate changes to monitor.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Meanwhile, commercial contracts frequently reference a percentage of Medicare. When Medicare rates shift and a payer applies the change incorrectly, the shortfall posts as a contractual adjustment unless someone compares each payment against the contract. That is the core of payer variance detection. For recent rate shifts, see how <a href=\"https:\/\/www.medicalbillersandcoders.com\/blog\/pathology-billing-alert-how-cms-updates-are-shaping-lab-test-reimbursement\/\">CMS updates are shaping lab test reimbursement<\/a>.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">In addition, labor adds pressure. Experienced pathology coders are hard to recruit and slow to train, and turnover in an in-house team shows up as coding backlogs and missed timely filing deadlines. For many groups, the cost of vacancy exceeds the cost of outsourcing.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">As a result, pathology billing services are judged less on price and more on how much revenue they keep from leaking. That is the lens a CFO or lab administrator should use when comparing vendors, and it is how MBC frames the conversation: the goal is to <strong>Yield your EBITDA<\/strong>, not to shave a point off the billing rate.<\/p>\r\n\r\n\r\n\r\n<h2 id=\"h-five-control-points-where-pathology-billing-services-lose-revenue\" class=\"wp-block-heading\">Five Control Points Where Pathology Billing Services Lose Revenue<\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>1. Charge capture at accessioning.<\/strong> First, every block, stain and special study must flow from the LIS into a claim. Missed 88312 or 88313 special stains, uncaptured frozen sections (88331, 88332) or under-counted IHC units rarely trigger a denial. They simply never get billed, so the loss stays invisible until someone reconciles case files against claims.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>2. Coding accuracy and leveling.<\/strong> Specimen leveling, add-on codes and medical necessity diagnoses must all match documentation. Undercoding protects against audits but erodes yield. On the other hand, overcoding raises compliance exposure. Strong pathology billing services audit leveling regularly and feed findings back to the pathologists.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>3. Component billing and client billing.<\/strong> Professional, technical and global billing must match who performed what work. Hospital outreach programs add client billing, where the lab invoices a hospital or physician office rather than the payer. Medicare&#8217;s anti-markup rule under 42 CFR 414.50 limits what can be billed for purchased diagnostic tests, and some states add their own restrictions on anatomic pathology markups, so rules must be checked state by state.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>4. The Date of Service rule.<\/strong> CMS&#8217;s 14-day rule under 42 CFR 414.510 determines whether a test on a hospital specimen is billed by the lab or bundled into the hospital stay. Molecular pathology and certain advanced diagnostic tests have an exception that allows direct lab billing when conditions are met. Misapplying the rule sends claims to the wrong party and delays payment for months.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>5. Payment variance and underpayments.<\/strong> However, without contract loading and automated comparison, underpaid claims look paid. Over thousands of claims, those gaps add up to meaningful revenue that a partner focused on <a href=\"https:\/\/www.medicalbillersandcoders.com\/revenue-management-services.aspx\">Revenue Recapture Services<\/a> can identify and appeal.<\/p>\r\n\r\n\r\n\r\n<h2 id=\"h-where-pathology-claim-denials-cluster\" class=\"wp-block-heading\">Where Pathology Claim Denials Cluster<\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Fortunately, <strong><a href=\"https:\/\/www.medicalbillersandcoders.com\/blog\/category\/claims-denials\/\">claim denials<\/a><\/strong> in pathology are predictable, which makes them preventable when the billing partner tracks them by root cause instead of resubmitting blindly.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Molecular and MolDX requirements.<\/strong> Palmetto GBA administers the MolDX program, and several other Medicare Administrative Contractors, including Noridian, have adopted it. Under MolDX, many molecular tests need a registered DEX Z-code on the claim and must meet a covering LCD. Labs in MolDX jurisdictions, from the Carolinas to California, see rejections when the Z-code is missing or the diagnosis does not support coverage.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>NCCI and MUE edits.<\/strong> National Correct Coding Initiative procedure-to-procedure edits and Medically Unlikely Edits limit how codes combine and how many units can be billed. For example, IHC and special stain combinations are frequent triggers, and correct use of modifier -59 or the X-modifiers requires documentation that supports distinct specimens.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Medical necessity.<\/strong> Screening-related codes such as G0416 for prostate saturation biopsy, and tests governed by National or Local Coverage Determinations, deny when the diagnosis code does not match covered indications. For Medicare patients, a properly executed Advance Beneficiary Notice protects the lab&#8217;s right to bill the patient.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Administrative gaps.<\/strong> Missing CLIA numbers, incorrect ordering provider NPIs and eligibility errors produce CARC codes such as CO-16 (missing information) and CO-97 (bundled service). Because data arrives on requisitions, these errors need front-end scrubbing rules, not back-end rework.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Prior authorization for genetic testing.<\/strong> Furthermore, commercial payers and benefit managers increasingly require authorization before genetic and molecular tests. A billing partner without authorization tracking will see these denials repeat month after month.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Turning Denial Data into Upstream Fixes<\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Effective <strong><a href=\"https:\/\/www.medicalbillersandcoders.com\/blog\/category\/denial-management\/\">denial management<\/a><\/strong> for pathology means reporting denials by CPT, payer and reason code, fixing the upstream cause, and measuring overturn rates. MBC calls this denial root-cause engineering.<\/p>\r\n\r\n\r\n\r\n<h2 id=\"h-how-to-evaluate-pathology-billing-services-before-you-sign\" class=\"wp-block-heading\">How to Evaluate Pathology Billing Services Before You Sign<\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">The table below translates the five control points and denial patterns into evaluation criteria a lab administrator can use in vendor interviews.<\/p>\r\n\r\n\r\n\r\n<div dir=\"ltr\">\r\n<table>\r\n<thead>\r\n<tr>\r\n<th scope=\"col\">Evaluation Criterion<\/th>\r\n<th scope=\"col\">What a Strong Partner Shows<\/th>\r\n<th scope=\"col\">Red Flag<\/th>\r\n<\/tr>\r\n<\/thead>\r\n<tbody>\r\n<tr>\r\n<td>Coding accuracy<\/td>\r\n<td>CPC\/CCS coders assigned to anatomic, clinical and molecular lines; regular leveling audits<\/td>\r\n<td>Generalist coders rotating across specialties<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Denial management<\/td>\r\n<td>Root-cause reporting by CPT, payer and CARC; tracked overturn rates<\/td>\r\n<td>Denials resubmitted without trend analysis<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Reimbursement management<\/td>\r\n<td>CLFS and fee schedule tracking; payer variance detection against loaded contracts<\/td>\r\n<td>No contract loading or underpayment flags<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>A\/R recovery<\/td>\r\n<td>Dedicated old AR recovery team with payer-class aging targets<\/td>\r\n<td>A\/R over 90 days above 20% with no plan<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Compliance<\/td>\r\n<td>Documented 14-day rule, anti-markup and ABN workflows<\/td>\r\n<td>No written compliance protocols<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>RCM infrastructure<\/td>\r\n<td>System-agnostic work in your LIS and PM; executive dashboards<\/td>\r\n<td>Mandatory platform migration<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<\/div>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">How to Verify What a Vendor Promises<\/h3>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Above all, ask for evidence on each row. A vendor that cannot show denial data by reason code from labs of your size is unlikely to deliver root-cause improvement. Similarly, a vendor that requires you to change your LIS adds implementation risk before any revenue improves. If you have not reviewed your workflow recently, start by <a href=\"https:\/\/www.medicalbillersandcoders.com\/blog\/analyze-your-current-pathology-billing-process\/\">analyzing your current lab billing process<\/a>.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">In practice, reporting matters as much as execution. Lab leadership should see clean claim rate, denial rate by payer, days in A\/R, A\/R over 90 days, and net collection rate at least monthly, with drill-down by client, test type and pathologist.<\/p>\r\n\r\n\r\n\r\n<h2 id=\"h-best-pathology-billing-companies-in-the-usa\" class=\"wp-block-heading\">Best Pathology Billing Companies in the USA<\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">The following five companies represent different delivery models. Descriptions are based on each company&#8217;s published positioning; verify capabilities directly during evaluation.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>1. Medical Billers and Coders (MBC).<\/strong> MBC provides <a href=\"https:\/\/www.medicalbillersandcoders.com\/speciality\/pathology-medical-billing-services.html\">outsourced pathology billing<\/a> services for multi-pathologist groups, independent anatomic and clinical labs, and hospital outreach programs. With 25+ years in revenue cycle work across all 50 states, MBC reports a 97% clean claim rate, a 30% A\/R reduction within 90 days for its clients, and 98% client retention. Its system-agnostic RCM infrastructure works inside your existing LIS and practice management system, so groups get coding, denial and A\/R ownership without a software rollout. Each engagement includes a dedicated RCM Principal and executive reporting, and pricing is custom-quoted after a data review.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>2. XiFin.<\/strong> San Diego-based XiFin combines a cloud-based revenue cycle platform with outsourced billing operations for diagnostic laboratories. It is a strong fit for high-throughput clinical and molecular labs that want a single platform with broad payer connectivity.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>3. TELCOR.<\/strong> TELCOR, headquartered in Lincoln, Nebraska, is widely known for laboratory billing software licensed to in-house billing teams, and it also offers revenue cycle services. It suits labs that intend to keep billing staff internal but need purpose-built lab billing technology.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>4. Quadax.<\/strong> Ohio-based Quadax offers SaaS, fully outsourced and hybrid models. Its pre-submission claim rules engine is well suited to molecular and genetic testing labs, where payer edits and coverage rules change often.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>5. APS Medical Billing.<\/strong> Based in the Toledo, Ohio area, APS Medical Billing has a long history serving pathology groups. It fits regional anatomic pathology practices that want a specialty-focused service team rather than a large platform vendor.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Pathology Billing Companies Compared at a Glance<\/h3>\r\n\r\n\r\n\r\n<div dir=\"ltr\">\r\n<table>\r\n<thead>\r\n<tr>\r\n<th scope=\"col\">Company<\/th>\r\n<th scope=\"col\">Delivery Model<\/th>\r\n<th scope=\"col\">Strongest Fit<\/th>\r\n<\/tr>\r\n<\/thead>\r\n<tbody>\r\n<tr>\r\n<td>MBC<\/td>\r\n<td>Outsourced RCM on your LIS\/PM<\/td>\r\n<td>Multi-pathologist groups and outreach labs needing coding, denial and A\/R ownership<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>XiFin<\/td>\r\n<td>Platform plus outsourced operations<\/td>\r\n<td>High-volume diagnostic and molecular labs<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>TELCOR<\/td>\r\n<td>Licensed software plus services<\/td>\r\n<td>Labs keeping billing in-house<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Quadax<\/td>\r\n<td>SaaS, outsourced or hybrid<\/td>\r\n<td>Molecular and genetic testing labs<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>APS Medical Billing<\/td>\r\n<td>Outsourced specialty billing<\/td>\r\n<td>Regional anatomic pathology groups<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<\/div>\r\n\r\n\r\n\r\n<h2 id=\"h-outsourced-in-house-or-hybrid-pathology-billing-services\" class=\"wp-block-heading\">Outsourced, In-House or Hybrid Pathology Billing Services<\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">The right model depends on where your margin gap sits.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Choose outsourced pathology billing services<\/strong> when coder recruitment, turnover or denial backlogs are limiting collections. A specialty partner brings trained pathology coders, established payer workflows and recovery capacity on day one. This model suits groups that want leadership attention on clinical growth and outreach rather than billing operations.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Keep billing in-house<\/strong> when your team is stable, experienced and mainly needs better technology and reporting. In that case, licensed lab billing software can give an internal team the scrubbing rules and dashboards it lacks.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Use a hybrid model<\/strong> when front-end processes, such as requisition intake and client billing for hospital outreach, are tightly tied to lab operations. For instance, many multi-site groups keep those functions internal and outsource coding, denial management and <a href=\"https:\/\/www.medicalbillersandcoders.com\/services\/old-ar-recovery-services\">old AR recovery<\/a>, where specialty depth delivers the largest return.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Whichever model you choose, insist on transparency.

Strong partners also split professional and technical components correctly and report denial root causes by CPT and payer.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-2\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">What is the difference between pathology billing and regular medical billing?<\/strong>\r\n<p class=\"schema-faq-answer\">Pathology billing differs because pathologists rarely see the patient, so demographics, insurance and diagnosis data arrive secondhand on a requisition. It also involves specimen-based CPT leveling, IHC unit counts, professional and technical component splits, client billing and lab-specific Medicare rules such as the 14-day rule and MolDX.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-3\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">Why do patients get a separate bill from a pathology lab?<\/strong>\r\n<p class=\"schema-faq-answer\">Patients often receive a separate bill because the pathologist who examined the tissue or blood sample works for an independent lab or pathology group, not for the physician who ordered the test. That group bills for its own interpretation and, in many cases, the technical lab work.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-4\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">How do you choose the best pathology billing company?<\/strong>\r\n<p class=\"schema-faq-answer\">Choose a partner with pathology-trained certified coders, proven MolDX and component billing workflows, and denial reporting by CPT, payer and reason code. Ask for clean claim rate, A\/R over 90 days and references from labs of your size, and confirm they work inside your existing LIS.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-5\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">Why are molecular pathology claims denied so often?<\/strong>\r\n<p class=\"schema-faq-answer\">Molecular claims are denied mainly because Medicare contractors in the MolDX program require a registered DEX Z-code and a test that meets a covering LCD. Commercial payers add prior authorization rules for genetic testing, so a billing partner needs both MolDX workflow and payer-specific authorization tracking.<\/p>\r\n<\/div>\r\n<\/div>\r\n\r\n\r\n\r\n<div class=\"schema-faq wp-block-yoast-faq-block\">\r\n<div id=\"faq-question-6\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">What is CPT code 88305 used for?<\/strong>\r\n<p class=\"schema-faq-answer\">CPT 88305 is Level IV surgical pathology, gross and microscopic examination. It covers common specimens such as skin biopsies, colon polyps and prostate needle biopsies. Because it is one of the highest-volume pathology codes, leveling errors on 88305 have an outsized revenue impact.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-7\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">What do modifiers 26 and TC mean in pathology billing?<\/strong>\r\n<p class=\"schema-faq-answer\">Modifier 26 bills only the professional component, which is the pathologist&#8217;s interpretation and report. Modifier TC bills only the technical component, such as specimen processing and slide preparation. When the same entity performs both, the service is billed globally without either modifier.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-8\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">How are IHC stains billed with CPT 88342 and 88341?<\/strong>\r\n<p class=\"schema-faq-answer\">Bill 88342 for the first single-antibody IHC stain per specimen and add-on code 88341 for each additional single-antibody stain on that same specimen. Multiplex stains use 88344. Units must match the antibodies and specimens documented, because MUE edits cap units per day.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-9\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">What is the 14-day rule in pathology billing?<\/strong>\r\n<p class=\"schema-faq-answer\">Under <a href=\"https:\/\/www.ecfr.gov\/current\/title-42\/section-414.510\" target=\"_blank\" rel=\"noopener noreferrer\">42 CFR 414.510<\/a>, a test on a hospital specimen ordered less than 14 days after discharge takes the collection date as its date of service, so the hospital generally bills it. Ordered 14 or more days later, the lab bills. Molecular tests and certain ADLTs have a direct-billing exception.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-10\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">What is client billing in pathology?<\/strong>\r\n<p class=\"schema-faq-answer\">Client billing means the lab invoices a hospital, physician office or other referring client for the test instead of billing the patient&#8217;s insurer. It is common in hospital outreach programs. Medicare&#8217;s anti-markup rule and state anatomic pathology laws limit when client billing and markups are allowed.<\/p>\r\n<\/div>\r\n<\/div>\r\n\r\n\r\n\r\n<div class=\"schema-faq wp-block-yoast-faq-block\">\r\n<div id=\"faq-question-11\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">How much do pathology billing services cost?<\/strong>\r\n<p class=\"schema-faq-answer\">Most pathology billing services price as a percentage of collections or per claim. MBC custom-quotes every engagement after reviewing your data. Compare vendors on total cost, including denial write-offs and aging A\/R, because a lower rate with weaker recovery usually costs a lab group more net revenue.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-12\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">What is a good clean claim rate for pathology billing?<\/strong>\r\n<p class=\"schema-faq-answer\">Most high-performing billing teams target a clean claim rate of 95% or higher, meaning claims pass payer edits on first submission. MBC reports a 97% clean claim rate. Track it alongside denial rate by payer and days in A\/R to see the full revenue picture.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-13\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">Should a pathology lab outsource billing or keep it in-house?<\/strong>\r\n<p class=\"schema-faq-answer\">Outsource when coder recruitment, turnover or denial backlogs are limiting collections, since a specialty partner brings trained pathology coders and payer workflows immediately. Keep billing in-house when your team is stable and mainly needs better software and reporting. Many multi-site groups choose a hybrid, keeping front-end client billing internal while outsourcing coding, denials and A\/R recovery.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-14\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">What&#8217;s the fastest way to fix aging pathology A\/R?<\/strong>\r\n<p class=\"schema-faq-answer\">The fastest way is to segment A\/R by payer and age, work claims still inside timely filing limits first, and correct the root denial reason before resubmitting. Dedicated <a href=\"https:\/\/www.medicalbillersandcoders.com\/services\/old-ar-recovery-services\">old AR recovery<\/a> teams prioritize high-dollar molecular and IHC claims. MBC reports a 30% A\/R reduction within 90 days for its clients.<\/p>\r\n<\/div>\r\n<div id=\"faq-question-15\" class=\"schema-faq-section\"><strong class=\"schema-faq-question\">How long does it take to switch pathology billing companies?<\/strong>\r\n<p class=\"schema-faq-answer\">A well-planned transition typically takes 30 to 90 days, covering a baseline A\/R audit, contract loading, LIS and clearinghouse connections, test claims and payer enrollment checks. Delays usually come from payer enrollment, so start credentialing updates early and keep the old vendor working runout.<\/p>\r\n<\/div>\r\n<\/div>\r\n","protected":false},"excerpt":{"rendered":"<p>The best pathology billing services in the USA come from specialty partners such as Medical Billers and Coders (MBC), XiFin, TELCOR, Quadax and APS Medical Billing, and the right choice depends on whether your lab needs outsourced coding and A\/R ownership, licensed lab billing software, or molecular denial expertise.
