Your practical estimate will appear here

We hold files from First_coast and Novitas across JH and JN, most recently effective Jan 1, 2025. A missing locality means our contractor coverage is incomplete—not that Medicare pays $0.

This is the published amount for this code—not necessarily the entire visit or procedure. A hospital may bill a separate facility charge, and other services, drugs, or supplies can add to the total.

CMS indicators that apply to 0818T: GLOB DAYS YYY (contractor decides) · MULT PROC 2 (standard reduction applies).

Global surgery period

Contractor decides

GLOB DAYS

YYY

Your Medicare Administrative Contractor decides whether a global period applies and sets its length when it prices the code. The result is 0, 10, or 90 days.

Multiple procedures

Standard reduction applies

MULT PROC

2

When billed with other procedures on the same date, the highest-valued one is paid at 100% and the next four at 50% each.

-51 depends on the other codes on the same claim, so it's a claim-level number rather than a per-code one.

Why would a Medicare claim for 0818T be denied or paid less?

These come from CMS indicators on this page, not general billing advice.

Payer-specific coverage and documentation rules live outside these files, so a claim that clears every check here can still be denied on other grounds.

What to check (5)

There is no national allowed amount for 0818T, so every reconciliation of this line runs against the MAC fee schedule that was in force for the date of service rather than against a national baseline.

  • Compare the paid amount against the MAC fee schedule in force for the date of service; there is no national allowed amount here to reconcile against.
  • Ask the MAC which global period it assigned: the contractor sets the follow-up window for this code, so whether a post-operative visit should have paid depends on the contractor that priced it.
  • Rank the claim’s procedure lines before calling a reduced line short-paid—under the standard multiple-procedure rule only the highest-valued one prices in full.
  • Expect an assistant-at-surgery denial here rather than appealing it—a -80 or -AS line on this procedure is never separately payable.
  • Reprice the line against the release, locality, setting, modifier and participation status that applied to the date of service before treating any difference as an underpayment.
