What 93505 covers
A cardiologist obtains small samples of heart muscle by advancing a biopsy catheter through vascular access into the heart, usually to sample the right ventricle. The specimens are sent for laboratory examination. A common indication is surveillance for rejection after heart transplantation; clinicians may also request tissue evaluation for suspected myocarditis or other myocardial disease. The service is typically performed in a cardiac catheterization laboratory or hospital procedure setting.
Report 93505 for the biopsy procedure, supported by documentation of the clinical indication and tissue sampling. When the diagnostic service is divided, modifier 26 identifies the professional interpretation and modifier TC identifies the technical service; without either modifier, the claim represents the global service. The 0-day global period includes same-day preoperative and postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

93505 billing questions
How is a heart biopsy different from right heart catheterization?
93505 reports sampling of heart muscle. A right heart catheterization such as 93451 reports hemodynamic catheter measurements; it may be performed during the same encounter when separately supported.
Can pathology be billed separately?
Yes. The biopsy procedure and the pathologist’s examination of the submitted tissue are distinct services; the pathology claim should reflect the examination actually performed.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation or TC for the technical service when those components are billed separately. Billing without either modifier represents the global service.
Does 93505 have a global period?
It has a 0-day global period, so same-day preoperative and postoperative care is included.
How are other same-session procedures paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures performed in that session are reduced.
Can modifier 50 or an assistant surgeon be reported?
Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documentation of medical necessity.
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.
