Billing tips

Always verify that the transseptal puncture was medically necessary and document the specific indication; retrograde arterial approach should be documented as contraindicated or unsuccessful if applicable
Impact: Prevents medical necessity denials which account for approximately 30% of rejections for this code
Do not separately bill CPT 93462 when transseptal puncture is performed as access for another primary procedure (e.g., mitral valve repair, left atrial appendage closure) - it is typically bundled
Impact: Avoids unbundling denials and potential audit flags; bundled payment is included in the primary structural heart procedure code
Ensure documentation includes hemodynamic measurements obtained from the left heart chambers and explicit mention of the transseptal puncture technique and approach
Impact: Complete documentation supports the full $196.02 reimbursement and withstands post-payment audits
When billing with right heart catheterization (93453), confirm that both procedures were medically necessary and document separate clinical indications for each
Impact: Combined procedures may trigger NCCI edits; proper documentation justifies combined payment of approximately $390-420
Report imaging guidance separately (e.g., 93662 for intracardiac echo during transseptal puncture) only when comprehensive imaging is performed and documented beyond routine fluoroscopic guidance
Impact: When appropriately documented, adds $150-300 to total reimbursement depending on imaging modality used
Verify place of service code matches the actual location; facility vs non-facility designation affects technical component billing but not the $196.02 professional payment

Frequently asked questions

What is the Medicare reimbursement rate for CPT 93462 in 2025?

The 2025 Medicare national average reimbursement for CPT 93462 is $196.02 for both facility and non-facility settings. This is based on 6.06 total RVUs (3.73 work RVU, 1.5 PE RVU, 0.83 MP RVU) multiplied by the 2025 conversion factor of 32.3465.

Can CPT 93462 be billed with mitral valve repair or TAVR procedures?

Generally no. CPT 93462 is typically bundled into structural heart intervention codes when transseptal puncture serves as access for the primary procedure. You cannot separately bill for transseptal access when performing mitral clip, left atrial appendage closure, or balloon mitral valvuloplasty unless there is a distinct diagnostic indication documented separately.

What is the difference between CPT 93462 and 93452?

CPT 93462 specifically describes left heart catheterization via transseptal puncture (through the atrial septum from venous access), while 93452 describes left heart catheterization via retrograde approach (through an artery). The transseptal approach is used when arterial access is contraindicated or for procedures requiring left atrial access.

How many RVUs is CPT 93462 worth in 2025?

CPT 93462 has 6.06 total RVUs in 2025, consisting of 3.73 work RVUs, 1.5 practice expense RVUs (both facility and non-facility), and 0.83 malpractice RVUs according to the CMS Medicare Physician Fee Schedule.

What documentation is required to bill CPT 93462?

Required documentation includes explicit mention of transseptal puncture technique, medical indication for this approach, confirmation of left heart access, hemodynamic measurements obtained from left-sided chambers, imaging guidance used, and any complications. The operative report must clearly distinguish this from routine right heart catheterization.

Can CPT 93462 be billed with right heart catheterization on the same day?

Yes, CPT 93462 can be billed with right heart catheterization codes (such as 93453) when both are medically necessary and documented. However, you must ensure documentation supports the medical necessity of obtaining both right and left heart hemodynamics and that separate clinical questions are being answered by each procedure.

What modifiers are commonly used with CPT 93462?

Common modifiers include modifier 26 for professional component only, modifier 59 for distinct procedural service when billed with other catheterization codes, modifier 22 for increased procedural complexity due to anatomical difficulty, and modifier 78 for return to the cath lab during a postoperative period. Modifier 53 is used if the procedure is discontinued for medical necessity.
