If you run an ambulatory surgery center (ASC), getting paid correctly is just as important as delivering great care to your patients. Yet many providers do not realize how much Medicare's payment rules shape their revenue, or how much opportunity they may be missing. At Altruis, we provide ASC billing services that give your organization the clarity and confidence to get paid what it has earned. That starts with understanding how the Centers for Medicare and Medicaid Services (CMS) determines your reimbursement in the first place.
What Good ASC Billing Services Catch That Others Miss
Medicare does not pay what you bill. It pays its own fixed rates, which are typically lower than what a hospital would receive for the same procedure. The reasoning is simple: ambulatory surgery centers carry lower overhead costs, and Medicare's reimbursement reflects that difference.
These rates are updated every year through the CMS Final Rule, released each November and effective January 1. Each update can bring changes to approved procedure lists, shifts in payment amounts, and adjustments to what gets reimbursed as a separate line item versus what gets grouped into a single bundled payment. These changes are detailed and easy to overlook, but their financial impact on your organization is anything but small. When providers are not tracking them closely, revenue can slip away quietly and consistently before it ever surfaces in the numbers.
Covered Procedures and Bundling Rules Shape Every Case
Medicare only reimburses procedures from a specific approved list. Anything outside that list is not covered, which affects how you schedule patients, structure your services, and plan your finances for the year ahead. It also has a direct effect on how you think about your patient population and payer mix.
Beyond procedure coverage, many supplies and add-on services are folded into the base procedure payment rather than billed separately, even when they added real cost to the case. This is called bundling, and it is one of the most common and overlooked sources of revenue loss for ASC providers. Understanding what is covered and what is bundled helps your organization see the true profitability of each case and puts you in a stronger position when negotiating with commercial insurance plans.
The Baseline Every Commercial Contract Is Built On
Most commercial payers use Medicare rates as their starting point when determining ASC reimbursement. If your organization does not have a clear picture of what Medicare pays for your most common procedures, you may be agreeing to contracts that quietly undervalue your services year after year without ever realizing it.
Staying current on annual Medicare rate changes gives your facility the leverage to approach contract negotiations with confidence, on your own timeline, and with the data to back up every conversation. Providers who understand the payment system are better positioned to advocate for fair reimbursement and protect their bottom line over the long term.
