What 93463 covers

During invasive cardiac catheterization, a clinician administers a pharmacologic agent and evaluates hemodynamic measurements before, during, and after the challenge. A familiar application is testing pulmonary vascular response during right-heart catheterization; agents such as adenosine or dobutamine may be used according to the clinical protocol. The service is typically performed in a cardiac catheterization laboratory by a cardiologist as part of an invasive hemodynamic study.

Report 93463 with the primary cardiac catheterization service, not as a stand-alone drug administration or monitoring service. The record should identify the agent and document the measurements and clinical response that support the pharmacologic assessment. CMS classifies 93463 as an add-on code: it is billed only with a primary procedure, and its payment falls within that procedure's global period. The primary catheterization and this additional challenge are reported as separate codes.

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.

93463 billing questions

When should I report 93463 rather than 93464?

Use 93463 when a pharmacologic agent is used for hemodynamic assessment during catheterization. Use 93464 when the hemodynamic study uses physiologic exercise.

Can 93463 be billed without a catheterization code?

No. It is an add-on code and must be reported with a primary cardiac catheterization service.

What documentation supports 93463?

Document the pharmacologic agent, the invasive hemodynamic measurements before, during, and after administration, and the clinical purpose and response.

Does 93463 replace the primary catheterization code?

No. Report the primary catheterization separately; 93463 represents the added pharmacologic hemodynamic assessment.

Is 93463 the code for a pharmacologic stress test?

No. It describes a drug challenge with hemodynamic assessment during cardiac catheterization, not a stand-alone stress test.

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.
