Rapid Influenza Antigen Test
CPT 87804
Performed at the point of care when a fast flu answer will guide antiviral treatment or the decision to keep someone home.
No national payment amount
Status X is not separately payable under the PFS.
Did Medicare pay separately for CPT 87804 in Q1 2026?
Not at a published national rate. CPT 87804 carries status X (statutory exclusion) in the Q1 2026 release. The statutory definition of physician services does not include this item. Treat the blank amount as unpriced, not as $0.
How often 87804 is billed
Across Original Medicare in CY2024, 87804 ranked #213 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 2.1 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 2026 fee schedule the rates above come from.
Common questions
Why is there no payment amount for 87804?
Its status indicator is X (statutory exclusion). The statutory definition of physician services does not include this item. 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 87804 be denied or paid less?
Each item below comes from a CMS indicator on this page — not general billing advice.
- Its status indicator is X (statutory exclusion) — The statutory definition of physician services does not include this item. 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.

What is a 87804 visit in patient-friendly terms?
In plain terms: The quick in-office flu test: a nasal swab is applied to a small test device and read by eye a few minutes later for a line or color change showing influenza proteins. Because it detects viral protein rather than genetic material, it is fast and inexpensive but less sensitive than PCR, so a negative in a clearly ill patient during flu season is often followed up with molecular testing. Influenza A and B are read as separate results. Think of the swab done right in the exam room, with the nurse returning ten minutes later to say it came up positive for flu A. You'll typically see CPT 87804 on a bill or explanation of benefits (EOB) when a clinician performs or bills for this service.
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.

Source & method
This is computed from CMS's Medicare Physician Fee Schedule Q1 2026 release (schedule pfs, effective January 2026). 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.
