How often 66983 is billed Copy link
Across Original Medicare in CY2024, 66983 ranked #6,367 of the 7,879 CPT codes billed to Medicare that year, ranked by patients served or total allowed dollars. Patients who received it in 2024 were billed for it an average of 2.5 times that year — more than once per patient.
2024 Medicare fee-for-service only, national totals — Medicare Advantage, Medicaid and commercial volume are excluded, so real-world use runs higher. This is a calendar-year snapshot from the CMS Physician & Other Practitioners dataset, on a different cycle from the Q1 2020 fee schedule the rates above come from.
Global period: what 66983's fee already covers Copy link
Major surgery. The fee covers the day before surgery, the day of surgery, and the 90 days after it. Related follow-up care inside that window is not billed separately.
Billing a related follow-up visit inside the 90-day window is the most common way this code gets denied — the payment for that care is already inside the 66983 fee.
| Modifier | Reports |
|---|---|
| -25 | A significant, separately identifiable E/M on the same day as the procedure, beyond its usual pre- and post-operative care. |
| -57 | The E/M at which the decision to operate was made. Major surgery only — a minor procedure has no day-before pre-operative period. |
| -24 | An E/M during the follow-up window that is unrelated to this surgery, so it is paid separately. |
| -58 | A staged or more extensive follow-on procedure during the window. Starts a new follow-up period. |
| -78 | An unplanned return to the operating room for a related procedure during the window. Does not start a new follow-up period. |
| -79 | An unrelated procedure by the same physician during the window. Starts a new follow-up period. |
A modifier reports what happened; it does not by itself make a service payable. Documentation has to support it.
Common questions Copy link
Why is there no payment amount for 66983?
Its status indicator is C (carrier-priced). Your Medicare Administrative Contractor prices this code case by case, usually after reviewing documentation. The blank is deliberate: the amount is either unknown or paid under another provision, so reading it as $0 would be wrong.
Why would a Medicare claim for 66983 be denied or paid less?
Each item below comes from a CMS indicator 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
- 66983 carries a 90-day global period — routine post-operative care within that window is included in the surgical payment rather than paid on its own claim. See how it's computed
- Assistant at surgery: never separately payable. See billing policy
- Co-surgeons: not permitted. See billing policy
- Team surgery: not permitted. See billing policy
- Multiple procedures: standard reduction applies. 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.
When does this rate change?
CMS publishes a fee schedule release every quarter (January, April, July, October), and each is versioned here. The 66983 rate last moved in Q1 2019 (-0.6% non-facility) — see its rate history or what changed each release, or get an email when a new release moves rates.

Billing policy Copy link
What 66983'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 | 1 | 150% bilateral adjustment applies. Billed bilaterally (modifier 50, or on both sides), Medicare pays 150% of the single-side fee schedule amount. |
| Assistant at surgery | 1 | Never separately payable. An assistant at surgery may never be separately paid for this procedure — a statutory restriction. |
| 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 | 2 | Standard reduction applies. The same standard ranking-and-reduction rule as indicator 1 applies to this procedure when billed with others on the same date. |
| Professional/technical split | 0 | No PC/TC split. This is a physician service code; the professional/technical split does not apply, and the code is billed as a single service. |

This is computed from CMS's Medicare Physician Fee Schedule Q1 2020 release (schedule pfs, effective January 2020). National amounts apply a GPCI of 1.000 and leave sequestration off. The status indicator decides payability, never the RVU values, so a blank RVU stays blank. Releases are immutable: a rate retrieved for a past quarter always reflects that release. Commercial and cash-pay figures anywhere on this page are arithmetic on the Medicare amount, using commonly cited reimbursement ranges. They're illustrative, and no nationwide claims database stands behind them. Our methodology covers all of this in depth — sourcing, parsing, versioning, and how claims are cross-checked before they ship.
