ASC Medical billing and coding: The fastest growing Healthcare service!

The Ambulatory Surgical Center (ASC) market has grown rapidly in recent years. As insurance limitations tighten and health costs rise, more and more people are turning to outpatient facilities for high-quality surgery at affordable rates. Outsourcing your ASC medical billing and coding helps you address many of your financial concerns and increases profitability. But recent reports indicate that, even though ASCs continue to be the fastest-growing segment of the healthcare industry, there are many challenges to improving revenue performance.

For an outpatient surgery center to bill for services, it must qualify and meet the requirements set by the Centers for Medicare and Medicaid Services (CMS). Remember that ASCs are either independent physician-owned or they are associated with a hospital or medical center.

Payment Procedure of Ambulatory Surgical Centers

For ASC to be reimbursed, the service provided must be a medical necessity. The medical procedure performed must meet certain requirements agreed upon by both the patient and the provider.

Does ASC require any specialty billing?

Ambulatory surgery service charging typically does not focus on a specific medical specialty or on particular procedures, services, or diagnoses. So, billing is unlike any medical specialty billing. But, Ambulatory Surgical Center medical billing uses the same techniques, codes, and guidelines as other medical entities. For example, ASC bills use CMS-1500 claim forms, while hospitals use UB-04 claim forms for reimbursement.

What type of services get covered?

Depending on the medical facility’s status, the ASC guidelines for covered services are outlined. When an ASC is fully credentialed, it can perform numerous procedures, making it the fastest-growing healthcare service.

Services not covered in ASC are:

  • Non-implantable durable medical equipment
  • Artificial arm, leg, and eyes
  • Physician services
  • Independent laboratory services
  • Ambulance services
  • Leg, back, neck, and arm braces
  • Prosthetic devices

Are procedural codes different?

As far as medical billing for ASC is concerned, procedural codes must be precise to ensure efficient, sufficient reimbursement. These codes vary depending on the procedures being performed and the type of medical facility where services are provided. The two vital codes used here are the ICD-10-PCS, which covers inpatient procedures, and the Current Procedural Terminology (CPT), which gives information regarding services rendered. These are applied along with ICD-10 diagnosis codes.

 Multi-specialty billing

Multiple specialties point towards a variety of underlying causes, diagnoses, and procedures. Keep in mind that charging for ASC multi-specialty procedures is complicated, but it is one of the fastest-growing healthcare services. To function efficiently, billing personnel should be knowledgeable in charging and coding, filing claims, managing customer service, and posting payments. Along with this, A/R follow-up, including denial management, has to be done.

4. What coding standards are essential for ASC billing?

  • ASC billing requires precise coding with CPT codes for outpatient procedures, ICD-10-PCS for inpatient procedures, and ICD-10 diagnosis codes. Accurate coding is essential to avoid claim denials and ensure correct reimbursement for the services provided.

5. What are the requirements for an ASC to bill and receive reimbursements from CMS?

  • To bill CMS, ASCs must be fully credentialed, qualify as a medically necessary facility, and meet Medicare and Medicaid standards. The procedures performed must meet specific requirements agreed upon by both the patient and provider to ensure compliance and eligibility for reimbursement.
