What good ASC billing execution looks like for Washington providers.

The Washington ASC billing market has its own quirks. Here is the operating discipline we install on every Washington engagement.

  1. Medicare ASC payment system (ASCFS) understandingASC Medicare payment follows Ambulatory Surgical Center Fee Schedule with distinct payment levels per CPT. Washington ASC billing teams need ASCFS-aware revenue forecasting.
  2. Implant + device pass-through billingSome implants and devices qualify for pass-through pricing in addition to procedure payment. Accurate device billing captures pass-through revenue otherwise lost.
  3. Charge capture across OR + ancillary servicesWashington ASCs leak 1-3 percent of net revenue to missed charges. Reconciliation against case logs catches gaps.
  4. Prior authorization for ASC proceduresCommercial PA for elective ASC procedures (orthopedic, GI, pain, ophthalmology) requires API-integrated submission and documentation packaging.
  5. Out-of-network ASC billing strategyWashington ASCs operating out-of-network with commercial payers need clean billing workflow, patient cost transparency, and dispute resolution capability.
  6. Multi-specialty case mix managementMulti-specialty ASCs need coders with depth across each specialty operating in the facility (ortho, GI, ophth, pain, ENT, etc.).
