CPT 66983
No national payment amount
Carrier-priced: no national payment amount.
Did Medicare pay separately for CPT 66983 in Q2 2021?
Not at a published national rate. CPT 66983 carries status C (carrier-priced) in the Q2 2021 release. Your Medicare Administrative Contractor prices this code case by case, usually after reviewing documentation. Treat the blank amount as unpriced, not as $0.

How often 66983 is billed
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 Q2 2021 fee schedule the rates above come from.
Common questions
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.

What is a 66983 visit in patient-friendly terms?
We haven't written the plain-language description for CPT 66983 yet — ask your provider's billing office what service it covers in the meantime.
How this amount is computed
amount = (work RVU × work GPCI + PE RVU × PE GPCI + MP RVU × MP GPCI) × conversion factor. National amounts use GPCI = 1.000. To price an RVU figure of your own, use the RVU-to-dollars converter.
| Component | RVU |
|---|---|
| Work RVU | blank |
| Practice expense RVU (non-facility) | blank |
| Practice expense RVU (facility) | blank |
| Malpractice RVU | blank |
Every rate combines three parts: work (the clinician’s time, skill and effort), practice expense (office overhead — higher when the service is done in a doctor’s own office), and malpractice (the share of liability-insurance cost). A blank means CMS publishes no national number for that part. Read it as unknown, and never as zero.
Billing policy
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 Q2 2021 release (schedule pfs, effective April 2021). 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.
Conversion factor $34.8931 read from the same file, row 11, column 25.
