Site of service: why the same procedure has three different economics

Office, ASC and hospital outpatient settings pay differently, cost differently and carry different risk. A plain-English map of the mechanics.

A thick ring binder of policy documents open on a shelf, its tabbed dividers catching the light.

In short

  • The professional payment, the facility payment and your own cost structure move independently across settings.
  • Medicare policy has repeatedly shifted the relative advantage between settings; a capital plan should not depend on one rule cycle.
  • Commercial contracts may not follow Medicare's setting differentials — check your own rates.

A urologist performing the same procedure in three settings is running three different businesses. Understanding which one you are in is the precondition for every capital decision that follows.

The three components

  • Professional payment for the physician's work — broadly, what the fee schedule pays the clinician.
  • Facility or technical payment for the site — which flows to whoever owns the site. If that is you, it is revenue; if it is a hospital, it is not.
  • Your cost to deliver — consumables, staff, equipment, space and the capital behind them, which differ enormously between an office room you own and a hospital suite you do not.

These three move independently. A setting can pay more in total while contributing less to your practice, and a setting can pay less while contributing more, depending entirely on which components you capture and what they cost you.

Why it keeps changing

Medicare payment policy revisits setting differentials regularly, and procedural specialties feel it disproportionately. The 2026 Physician Fee Schedule is the current example, with an efficiency adjustment applied to the work component of many non-time-based services and continued attention to how procedures are paid across settings. Independent urology advocacy — LUGPA's work on prostate biopsy payment being one visible thread — exists precisely because these mechanics determine whether independent practice remains economically viable.

What to do with this

Two things. First, know your own contracted commercial rates by setting; they do not automatically mirror Medicare's structure. Second, when you model a capital investment, run it at the current differential and again at a materially less favourable one. If the plan only works at today's rates, you are underwriting regulatory risk you have not priced.
