What is a 99606 visit in patient-friendly terms?
CPT 99606 is a billing code clinicians use to identify a specific service or procedure on a claim or explanation of benefits (EOB). We don't have a plain-language description on file for this exact code yet — ask your provider's billing office what service it represents, or bring it up at your next visit.
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.
| 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 value of blank means CMS publishes no national number for that part — which is not the same as zero.
