CPT 99418
No national payment amount
Status I is not separately payable under the PFS.
Does Medicare pay separately for CPT 99418 in 2026?
Not at a published national rate. CPT 99418 carries status I (not valid) in the Q3 2026 release. Medicare uses a different code to report and pay for this service. Treat the blank amount as unpriced, not as $0.
Common questions
Why is there no payment amount for 99418?
Its status indicator is I (not valid). Medicare uses a different code to report and pay for this service. 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 99418 be denied or paid less?
Each item below comes from a CMS indicator on this page — not general billing advice.
- Its status indicator is I (not valid) — Medicare uses a different code to report and pay for this service. See status indicators
- 412 codes can never be billed with 99418 on the same date of service — NCCI denies those pairs even with a modifier. See billing together
- 167 codes pair with 99418 only when modifier 59 (or XE, XS, XP, XU) documents a distinct service — billed together 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 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 Q3 2026 release (schedule pfs, effective July 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.
