    The Old AR Problem: Why Aging Receivables Are a Practice Survival Issue<\/h2>\r\n

    Old AR \u2014 claims that have aged 90 days or more without resolution \u2014 represents the most recoverable revenue loss category in medical billing. Unlike write-offs caused by patient bad debt or contractual adjustments, old AR is typically collectible if pursued within payer timely filing limits. The problem is that most billing companies \u2014 including the ones currently managing the practice \u2014 have already deprioritized these claims in favor of current claim volume.<\/p>\r\n

    The result:<\/strong> a 90-120 day AR bucket that grows monthly, a 120+ day bucket that approaches timely filing limits, and a slow accumulation of claim value that becomes permanently uncollectible without intervention.<\/p>\r\n

    For a physician group billing $300,000 monthly, a 90+ day AR bucket at 22% of total AR \u2014 above the 15% threshold that indicates billing underperformance \u2014 represents $66,000 in receivables at acute collection risk.<\/p>\r\n

    At $500,000 monthly, the same proportion is $110,000 at risk per month. An AR recovery specialist who resolves 70% of that bucket recovers $46,200-$77,000 that the current billing vendor has effectively written off without formal write-off authorization.<\/p>\r\n

    Understanding Timely Filing Limits: The Hard Deadline for AR Recovery<\/h2>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

    Timely filing limits vary by plan, state, and contract. Individual payer contracts may override these general limits. Verify limits for each specific payer contract before initiating AR recovery.<\/em><\/p>\r\n

    What Separates AR Recovery Specialists from Standard Billing Vendors<\/h2>\r\n

    Standard billing vendors manage current claim volume. AR recovery requires a fundamentally different operational model: a team dedicated exclusively to aged claims, with the time, payer intelligence, and appeal infrastructure to pursue denials that standard billing workflows have already cycled through without resolution.<\/p>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

    Top RCM Companies for Old AR Recovery (2026) \u2014 Ranked<\/h2>\r\n

    #1 \u2014 Medical Billers and Coders (MBC)<\/h3>\r\n

    Best For: Physician groups and ASCs with aging AR in the 90-120+ day bucket from prior billing company underperformance, transition periods, or internal billing team gaps.<\/p>\r\n

    MBC’s Old AR Recovery service<\/a> is a dedicated operational protocol \u2014 not a feature of the standard billing service. When a physician group engages MBC for AR recovery, the dedicated team begins with a full AR audit: every claim in the 90-120+ day bucket is categorized by payer, denial reason, dollar value, and timely filing deadline. Claims are prioritized by recovery probability and timely filing urgency \u2014 not by claim age alone \u2014 ensuring that the highest-value recoverable claims are pursued first, before payer appeal windows close.<\/p>\r\n

    For medical necessity denials \u2014 the most common driver of aging AR in complex specialties \u2014 MBC initiates peer-to-peer review requests with the treating physician and the payer medical director within the payer’s published review window. Peer-to-peer reviews convert medical necessity denials to approvals at a documented rate of 60-78% when initiated within 30 days of denial.<\/p>\r\n

    Most standard billing vendors never initiate peer-to-peer review because the process requires physician time and a dedicated appeals coordinator \u2014 two resources that standard billing operations do not allocate to aged claims.<\/p>\r\n

    Appeal packages include payer-specific clinical documentation support: MBC’s appeal writers construct the medical necessity argument around the payer’s specific LCD<\/a> or coverage policy, not a generic appeal letter that payers routinely deny on form alone. For complex specialty denials \u2014 interventional procedures, wound care, orthopedic surgery \u2014 the clinical specificity of the appeal is the primary determinant of whether the denial is overturned.<\/p>\r\n

    AR Recovery Performance: <\/strong>60-75% recovery rate on 90-120 day AR | Peer-to-peer review for medical necessity | Timely filing deadline tracking | All specialties | All U.S. states | 888-357-3226<\/p>\r\n

    #2 \u2014 Coronis Health<\/h3>\r\n

    Coronis Health provides AR recovery services within its enterprise RCM infrastructure. For health system-affiliated physician groups with institutionally structured AR recovery workflows, Coronis offers functional denial resolution and appeal management. Independent physician groups evaluating Coronis for standalone AR recovery should confirm the team allocation model: AR recovery performance depends on dedicated team capacity, not shared current-billing resources.<\/p>\r\n

    #3 \u2014 R1 RCM<\/h3>\r\n

    R1 RCM’s enterprise denial management infrastructure includes AR recovery capabilities for hospital systems and large physician group networks. The institutional scale is genuine for high-volume operations. Independent physician groups should evaluate R1’s AR recovery pricing model \u2014 enterprise contracts may not provide cost-efficient AR recovery for practices with $50,000-$500,000 in aged receivables.<\/p>\r\n

    #4 \u2014 GeBBS Healthcare Solutions<\/h3>\r\n

    GeBBS provides AR recovery services through its offshore operational model. Timely filing deadline tracking and payer-specific appeal management should be verified at the engagement level. Peer-to-peer review coordination \u2014 which requires domestic scheduling with payer medical directors \u2014 should be explicitly scoped in any GeBBS AR recovery engagement.<\/p>\r\n

    #5 \u2014 Athenahealth<\/h3>\r\n

    Athenahealth’s denial management workflow within the athenaOne platform includes automated follow-up on denied claims. AR recovery for claims outside the standard denial workflow \u2014 pre-athenaOne claims, transition-period AR, or claims from prior billing systems \u2014 requires manual engagement that the platform’s automated denial management layer does not handle by default.<\/p>\r\n

    #6 \u2014 Avenue Billing Services<\/h3>\r\n

    Avenue Billing Services provides structured AR recovery protocols with systematic denial root-cause analysis for mid-market physician groups. The operational focus on preventable denial suppression extends to aged AR, with tiered escalation for claims approaching timely filing limits. Peer-to-peer review and complex specialty appeal capability should be confirmed at the engagement level.<\/p>\r\n
