Common questions Copy link

Why do Medicare rates in Hawaii, Guam differ from the national amount?
For nationally priced Physician Fee Schedule services, Medicare adjusts each code's work, practice-expense, and malpractice RVUs by this locality's three GPCIs before applying the conversion factor. Local costs for physician work, running an office, and liability insurance therefore move the final amount up or down. Hawaii, Guam currently has mixed GPCI components, so the net payment effect varies by code for the Q4 2021 release.
How do I know if my address is in this locality?
Medicare payment localities are geographic fee-schedule areas, commonly defined with county boundaries. CMS uses the ZIP code where the service was performed to assign a claim to its contractor and locality. Look up your ZIP to find your locality. A few ZIPs nationally span multiple localities and need ZIP+4 to resolve exactly.
Do commercial insurers or Medicare Advantage plans use this locality?
Original Medicare uses these PFS localities directly. Commercial and Medicare Advantage plans are not required to use the same locality structure. A contract may pay a percentage of Medicare, but its own wording decides which Medicare release, percentage, geography, and adjustments apply.
Does my locality affect what I owe as a patient?
For a covered service, a higher allowed amount in your locality usually means a higher 20% coinsurance. The effect depends on the code, the beneficiary's deductible, supplemental coverage, and other claim circumstances.
Why did my Medicare payment change even though I didn't change what I billed?
CMS publishes updated PFS files during the year. A code's amount can change because of conversion-factor, RVU, policy, or correction updates. GPCIs are usually set once a year in the fee schedule rule, though later files can correct them. See what changed each release.

Source & method Copy link

We compute GPCIs and rates from the CMS Medicare Physician Fee Schedule Q4 2021 release (effective October 2021). ZIP coverage from the CMS ZIP-to-locality crosswalk, Q3 2021 release. Example amounts use the standard (non-QP) physician conversion factor ($34.8931) and apply this locality's GPCIs to nationally priced Office (non-facility) RVUs, before the ~2% sequestration cut. Past releases are never edited, so a rate for an earlier quarter always matches what CMS published for it.
