CMS indicators that apply to 0661T: GLOB DAYS YYY (contractor decides) · BILAT SURG 1 (150% bilateral adjustment applies) · MULT PROC 2 (standard reduction applies).
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.
150% bilateral adjustment applies
BILAT SURG
1
Billed bilaterally (modifier 50, or on both sides), Medicare pays 150% of the single-side fee schedule amount.
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 0661T be denied or paid less?

Reconciling a contractor-priced payment for 0661T Copy link
What to check (5)
There is no national allowed amount for 0661T, 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.
- Look for modifier 50 or a second-side line before comparing: billed for both sides, this procedure should price at 150% of the single-side amount.
- 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.
