Fee schedule: the allowed amount per code

Behind every allowed amount is a fee schedule. Knowing which one applies tells you whether a CO-45 write-off is correct or disputable.

A fee schedule is a list of the maximum amounts a payer will allow for each billed code. Medicare uses the Medicare Physician Fee Schedule (MPFS); commercial payers use their own, often set as a percentage of Medicare. For an in-network claim, the fee-schedule amount is the allowed amount.

How it's used

  • The allowed amount for a code comes from the applicable fee schedule (or your contract).
  • The difference between your charge and the fee-schedule amount is a contractual adjustment (CO-45).
  • The patient's cost-share (deductible, coinsurance, copay) comes out of the allowed amount.

Frequently asked

Is the fee-schedule amount what I get paid?
It's the ceiling. The plan pays the allowed amount minus the patient's cost-share, which the patient then owes.
Where does the Medicare fee schedule come from?
It's built from RVUs adjusted by geography (GPCI) and a conversion factor — the RBRVS system.
