What 93595 covers
This service is left-heart catheterization performed to evaluate congenital heart disease, whether native cardiac connections are normal or abnormal. A cardiologist advances a catheter to the left side of the heart to assess pressures and cardiac hemodynamics, typically in a hospital catheterization laboratory. It is distinct from right-heart-only catheterization and from combined right- and left-heart catheterization; the combined codes also distinguish native-connection status.
Medicare assigns physician fee schedule status C: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The service has professional and technical components. Modifier 26 identifies the professional interpretation; modifier TC identifies equipment and staff; billing without either modifier represents the global service. Its 0-day global period includes same-day preoperative and postoperative care.

93595 billing questions
Does this code distinguish normal from abnormal native connections?
No. It describes left-heart catheterization for congenital heart disease without separating cases by native-connection status.
When is this code used instead of a right-heart catheterization code?
Use this code for a left-heart study. Codes 93593 and 93594 describe right-heart catheterization, with the applicable code depending on native connections.
When should a combined right- and left-heart code be considered?
When both sides of the heart are catheterized, compare the service with 93596 or 93597. Those codes distinguish normal from abnormal native connections.
How are modifiers 26 and TC used?
Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service, including equipment and staff. Without either modifier, the code represents the global service.
How does Medicare price this code?
Physician fee schedule status C means CMS publishes no national payment. The Medicare Administrative Contractor sets payment for each claim.
