Plain-text summaryReport a problem

CPT 88342 has no published national rate. It carries status I (not valid) in the Q4 2014 release. Medicare uses a different code to report and pay for this service. The blank amount means unpriced, not $0.

Why is there no national PFS amount for 88342?

Its status indicator is I (not valid). Medicare uses a different code to report and pay for this service. Status I is not separately payable under the PFS.

Global period: what 88342's fee already covers Copy link

XXX Does not apply

The global surgery concept does not apply to this code.

Billing policy Copy link

These billing-policy indicators explain how 88342 is treated. They apply whether the code is nationally priced or carrier-priced: a restriction like "bilateral not allowed" still matters on a carrier-priced code.

Policy Value What it means
Bilateral surgery 0 No bilateral adjustment. The 150% bilateral payment adjustment does not apply to this procedure.
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 multiple-procedure reduction applies when this procedure is billed with others on the same date; each is paid at its full fee schedule amount.
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.

Why a 88342 line may not pay separately Copy link

CMS publishes no separately payable amount for 88342 in this release, so reconciling the line means establishing which status governed the date of service rather than chasing a fee-schedule difference.

What to check

  • Confirm the status that governed the date of service before working this line as a short payment—CMS publishes no separately payable fee-schedule amount for it in this release.
  • 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.
  • 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.

Compare against 88334, 88333 and 88346: their amounts are in Related codes.

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 2014 fee schedule above.

Who bills 88342 to Medicare

Observed CY2024 Medicare fee-for-service billing, by the rendering clinician's CMS specialty. Each share is that specialty's slice of all observed services for this code that year.

Setting split that year: 39% Office (non-facility) · 61% facility. CMS publishes only this facility vs non-facility split, never the exact place of service. The Office (non-facility) figure does not identify urgent care or any other specific setting.

CY2024 Medicare fee-for-service only, from the CMS Physician & Other Practitioners dataset, which suppresses rows under 11 beneficiaries. We omit specialty groups with fewer than 30 observed clinicians, so the shares can fall short of 100%. Specialty and practice-type pages linked elsewhere on this page are curated code lists, not utilization claims.

Source & method

Show sources

This page uses CMS's Medicare Physician Fee Schedule Q4 2014 release (effective October 2014). National baselines use GPCI 1.000 and exclude sequestration. Whether a national amount exists depends on the status and CMS’s payment instructions; blank RVUs are never treated as zero. Past releases are never edited, so these sources stay valid after CMS publishes a newer one. Our methodology explains sourcing, parsing, versioning, and how we cross-check claims before we publish them.
