Reconciling a contractor-priced payment for 0637T Copy link
There is no national allowed amount for 0637T, 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.
What to reconcile
- 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.
- Confirm which component the line carried before comparing anything: the same code prices three ways—globally, as a professional component with modifier 26, and as a technical component with modifier TC.
- Confirm both sides were priced at 100%: this procedure takes no bilateral adjustment, though anything else billed the same day may still rank under the multiple-procedure rule.
- Check for documentation on file before appealing an assistant-at-surgery denial: payment on the -80 or -AS line is restricted for this procedure unless medical necessity is established.
- 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.

Billing policy Copy link
What 0637T's billing-policy indicators mean. These show for every code, priced or not: a restriction like "bilateral not allowed" still matters on a carrier-priced code.
| Policy | Value | What it means |
|---|---|---|
| Bilateral surgery | 3 | Both sides paid at 100%. No special bilateral adjustment applies here—each side is paid at 100% of the fee schedule amount, subject to the usual multiple-procedure rules for other services billed the same day. |
| Assistant at surgery | 0 | Restricted without documentation. Payment for an assistant at surgery is restricted for this procedure unless supporting documentation establishes medical necessity. |
| Co-surgeons | 0 | Not permitted. Medicare does not recognize co-surgeons (modifier 62) for this procedure. |
| Team surgery | 0 | Not permitted. Medicare does not recognize a surgical team (modifier 66) for this procedure. |
| Multiple procedures | 0 | No reduction. No payment reduction applies when this procedure is billed with other procedures on the same date—each is treated as unrelated. |
| Professional/technical split | 1 | Splits into professional and technical. This procedure splits into a professional component (modifier 26) and a technical component (modifier TC), each separately payable. |

Common payment questions Copy link
Why would a Medicare claim for 0637T be denied or paid less?
These come from CMS indicators on this page, not general billing advice.
- Its status indicator is C (carrier-priced)—Your Medicare Administrative Contractor prices this code case by case, usually after reviewing documentation. See status indicators
- 0637T splits into a professional component (modifier 26) and a technical component (modifier TC)—a claim for only one part needs that modifier to price correctly. See billing policy
- Assistant at surgery: restricted without documentation. See billing policy
- Co-surgeons: not permitted. See billing policy
- Team surgery: not permitted. See billing policy
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.
