Why is there no national PFS amount for 01402?
Its status indicator is J (anesthesia). Medicare prices this under the anesthesia formula—(base units + time units) × the locality anesthesia conversion factor—not the standard RVU formula. Ask for a locality to see that factor. Anesthesia code: paid via base + time units × a separate anesthesia conversion factor, not the standard PFS RVU formula. Supply a locality (and time_minutes for a specific amount) to compute it.

Billing together (NCCI edits) Copy link
NCCI Q4 2026Based on CMS's National Correct Coding Initiative (NCCI). A few examples appear here; use the complete edit page to check a specific pair.
Not separately payable with 01402 on the same date of service—no modifier bypasses the edit (modifier indicator 0)
Showing 3 of 152.
Separately payable with 01402 only when an NCCI-associated modifier is appropriate and documented (modifier indicator 1)
Showing 3 of 162.
Modifier 59 and the X modifiers are not a universal bypass—CMS expects the most specific applicable modifier, and which one that is depends on the pair and the documented circumstances.
Common payment questions Copy link
Why would a Medicare claim for 01402 be denied or paid less?
These come from CMS indicators on this page, not general billing advice.
- 152 codes form NCCI pairs with 01402 carrying modifier indicator 0—no NCCI-associated modifier bypasses the edit, so billed together on the same date of service, a line of the pair denies. See billing together
- 162 codes pair with 01402 under modifier indicator 1—separately payable only when an NCCI-associated modifier (59, or a more specific XE, XS, XP, or XU) is clinically appropriate and the documentation supports a distinct service; without one, a line of the pair denies. See billing together
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. See what changed each release, or get an email when a new release moves rates.

How often 01402 is billed Copy link
Across Original Medicare in CY2024, 01402 ranked #204 of the 7,879 CPT codes billed to Medicare that year, by patients served or total allowed dollars. It repeats: a patient billed for it in 2024 was billed 1.5 times on average that year.
2024 Medicare fee-for-service national totals. They exclude Medicare Advantage, Medicaid and commercial volume, 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 Q4 2026 fee schedule above.

The anesthesia estimate uses the base units, case length, and locality conversion factor identified beside that estimate. The PFS file establishes the pricing pathway. Releases are immutable: historical evidence remains tied to the specified release. Our methodology covers the depth: sourcing, parsing, versioning, and how we cross-check claims before they ship.
