Add-On: Real-Time Microscopic Imaging During Bile Duct Endoscopy
CPT 0397T
Reported as an add-on when a gastroenterologist uses real-time microscopic imaging during ERCP to evaluate an indeterminate bile duct narrowing.
No national payment amount
Carrier-priced: no national payment amount.
Does Medicare pay separately for CPT 0397T in 2026?
Not at a published national rate. CPT 0397T carries status C (carrier-priced) in the Q3 2026 release. Your Medicare Administrative Contractor prices this code case by case, usually after reviewing documentation. Treat the blank amount as unpriced, not as $0.
Common questions
Why is there no payment amount for 0397T?
Its status indicator is C (carrier-priced). Your Medicare Administrative Contractor prices this code case by case, usually after reviewing documentation. 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 0397T be denied or paid less?
Each item below comes from a CMS indicator on this page — not general billing advice.
- Its status indicator is C (carrier-priced) — Your Medicare Administrative Contractor prices this code case by case, usually after reviewing documentation. See status indicators
- 76 codes can never be billed with 0397T on the same date of service — NCCI denies those pairs even with a modifier. See billing together
- 163 codes pair with 0397T 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
- Bilateral surgery: no bilateral adjustment. See billing policy
- Assistant at surgery: restricted without documentation. See billing policy
- Co-surgeons: not permitted. See billing policy
- Team surgery: not permitted. See billing policy
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.

What is a 0397T visit in patient-friendly terms?
In plain terms: An add-on procedure performed during an ERCP - an endoscopy that examines the bile and pancreatic ducts - in which a specialized probe captures real-time, cell-level images of tissue inside the duct. It is used to help distinguish a benign narrowing from a cancerous one when standard biopsy or brushing taken during the same ERCP has not given a clear answer, and it is always billed alongside the primary ERCP code rather than on its own. Think of a patient whose imaging shows a narrowed bile duct that could be scar tissue or could be an early cancer, where a standard biopsy taken during ERCP was inconclusive. During the same procedure, the endoscopist passes a tiny imaging probe into the duct to look at the tissue at a cellular level in real time, helping decide whether more aggressive workup is needed right away. You'll typically see CPT 0397T 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.
Billing policy
What 0397T's billing-policy indicators mean. These show for every code, priced or not: 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 payment reduction applies when this procedure is billed with other procedures on the same date — each is treated as unrelated. |
| Professional/technical split | 0 | No PC/TC split. This is a physician service code; the professional/technical split does not apply, and the code is billed as a single service. |

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.
