HCPCS Q4121

Theraskin

No national payment amount

Status E is not separately payable under the PFS.

Did Medicare pay separately for HCPCS Q4121 in Q3 2020? Copy link

Not at a published national rate. HCPCS Q4121 carries status E (excluded) in the Q3 2020 release. A regulation removes this code from the fee schedule. When covered, it is paid under reasonable charge procedures instead. Treat the blank amount as unpriced, not as $0.

Common questions Copy link

Why is there no payment amount for Q4121?

Its status indicator is E (excluded). A regulation removes this code from the fee schedule. When covered, it is paid under reasonable charge procedures instead. 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 Q4121 be denied or paid less?

Each item below comes from a CMS indicator on this page — not general billing advice.

  • Its status indicator is E (excluded) — A regulation removes this code from the fee schedule. When covered, it is paid under reasonable charge procedures instead. See status indicators

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.

Source & method

Show sources

This is computed from CMS's Medicare Physician Fee Schedule Q3 2020 release (schedule pfs, effective July 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. CMS owns the code description shown for HCPCS Level II codes. 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.
