What 93464 covers

This add-on captures hemodynamic measurements taken while a patient exercises during cardiac catheterization, commonly using bicycle or arm ergometry. Cardiologists and other physicians performing catheterization may use it when symptoms such as exertional dyspnea are not explained by resting measurements, or when they need to assess exercise-related changes in cardiac filling or pulmonary pressures. Cardiac output may be measured, with or without oxygen-consumption measurement, as part of the exercise assessment.

Report 93464 with the primary cardiac catheterization code for the procedure performed; it is not a stand-alone service. The record should identify the exercise method and document the relevant baseline and exercise measurements and physician interpretation. CMS treats it as an add-on paid within the primary procedure’s global period. The diagnostic test has professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and no modifier represents the global service.

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.

93464 billing questions

Can 93464 be billed by itself?

No. It is an add-on and must be reported with the primary cardiac catheterization code for the procedure performed.

How is 93464 different from 93463?

93464 reports hemodynamic assessment during physiologic exercise, such as bicycle or arm ergometry. 93463 is the related add-on for assessment involving administration of a pharmacologic agent.

Which component modifier should the claim use?

Use modifier 26 for the professional interpretation or TC for the technical service involving equipment and staff. Without a modifier, the claim represents the global service.

What documentation supports reporting 93464?

Document the exercise method, the hemodynamic measurements obtained at rest and during exercise, and the physician’s interpretation of the findings.

Is 93464 paid within the catheterization global period?

Yes. CMS identifies 93464 as an add-on paid within the global period of the primary procedure.

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.
