Common questions Copy link

Why do Medicare rates in Suburban Chicago, Il 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 professional labor, office-input, and liability costs therefore move the final amount up or down. Suburban Chicago, Il currently has all three GPCI components at or above the national baseline, so normally RVU-priced services tend to price above the national amount for the Q4 2022 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 service-location ZIP code to map a claim to the applicable carrier and locality. Look up your ZIP to find your locality. About 30 ZIP codes in Suburban Chicago, Il span more than one locality and need the 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 benchmark payment to Medicare, but its language controls the Medicare release, percentage, geographic basis, and other adjustments.

Does my locality affect what I owe as a patient?

For a particular covered service, a higher locality-adjusted allowed amount generally produces a higher percentage-based coinsurance amount. 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. GPCI policy values are generally established through annual rulemaking, although later files can contain corrections. See what changed each release.
