Common questions

Why do Medicare rates in Los Angeles-Long Beach-Anaheim (Los Angeles/Orange County) differ from the national amount?

Medicare scales each code's work, practice-expense, and malpractice RVUs by this locality's three GPCIs before applying the conversion factor. Local labor, rent, and liability costs therefore move the final amount up or down. Los Angeles-Long Beach-Anaheim (Los Angeles/Orange County) currently pays above the national average for the Q2 2026 release.

How do I know if my address is in this locality?

Medicare assigns localities by ZIP code rather than by city or county lines, so neighboring addresses can fall in different localities. Look up your ZIP to find your locality. About 6 ZIP codes in Los Angeles-Long Beach-Anaheim (Los Angeles/Orange County) span more than one locality and need the ZIP+4 to resolve exactly.

Do commercial insurers or Medicare Advantage plans use this locality?

No. Medicare payment localities belong to Original Medicare's Physician Fee Schedule alone. Medicare Advantage plans and commercial insurers set their own geographic adjustments and negotiated network rates. They're free to draw their own boundaries, though many still benchmark off the Medicare amount.

Does my locality affect what I owe as a patient?

Yes. Original Medicare calculates your 20% coinsurance on the locality-adjusted amount rather than the national one. The same code can therefore leave you owing more or less depending on where you're treated. Los Angeles-Long Beach-Anaheim (Los Angeles/Orange County) pays above the national average, so patients here typically owe a bit more in coinsurance than the national amount would suggest.

Why did my Medicare payment change even though I didn't change what I billed?

GPCIs and the conversion factor update with each quarterly CMS release (January, April, July, October). The same code in the same locality can therefore pay a different amount quarter to quarter, with nothing on your end changing. See what changed each release.
