What 92979 covers

This add-on code represents intravascular ultrasound or optical coherence tomography imaging of an additional coronary vessel. A cardiologist or interventional cardiologist typically performs or interprets the imaging during a catheter-based evaluation or treatment, such as a coronary intervention. The imaging catheter provides views from inside the vessel to assess its structure and the result of treatment. Report this code for an additional vessel beyond the first vessel represented by the primary imaging code.

Medicare assigns this code carrier-priced status under the physician fee schedule: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. It is an add-on code and must be reported with a primary procedure; Medicare treats its payment within that procedure’s global period. Modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff portion, and no modifier represents the global service. Documentation should support imaging of each additional vessel reported.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

92979 billing questions

How does this code differ from 92978?

92978 represents imaging of the first vessel. Use 92979 for each additional vessel imaged in the same service.

Can 92979 be reported by itself?

No. It is an add-on code and must be reported with a primary procedure, including the first-vessel imaging code when applicable.

What does one unit represent?

One unit represents imaging of one additional vessel beyond the first vessel. The record should identify the additional vessel imaged.

When should modifier 26 or TC be used?

Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service, including equipment and staff. Reporting without a modifier represents the global service.

How does Medicare price this code?

The physician fee schedule classifies it as carrier priced, with no national payment published by CMS. The Medicare Administrative Contractor sets payment for the claim.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
