What 93583 covers
An interventional cardiologist uses a catheter to deliver alcohol into a selected septal coronary branch, creating a controlled injury in the thickened heart muscle to reduce obstruction to blood flow. The procedure is typically performed in a hospital catheterization laboratory for a patient with obstructive hypertrophic cardiomyopathy. Temporary pacemaker insertion and selective coronary angiography, when performed as part of the treatment, are included in this service.
Report the code for the transcatheter septal-reduction treatment, not for closure of a congenital septal defect. The procedure report should support the indication, target branch, and treatment performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery payment requires documented medical necessity; co-surgeon and team-surgery payment are not permitted.
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.

93583 billing questions
When should 93583 be selected instead of a septal defect closure code?
Use 93583 for catheter-directed reduction of hypertrophied heart muscle, typically in obstructive hypertrophic cardiomyopathy. Codes such as 93580 and 93581 describe closure of an atrial or ventricular septal defect.
Can selective coronary angiography be reported separately?
Selective coronary angiography performed as part of the septal-reduction treatment is included in 93583. The code also includes temporary pacemaker insertion when performed.
What supports reporting 93583?
The record should identify the clinical indication and document the catheter-based septal-reduction treatment, including the target branch and intervention performed.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's payment. The 0-day global period does not extend routine global care beyond the procedure date.
How are other procedures in the same session paid?
CMS pays the highest-valued procedure in full and applies the standard multiple-procedure reduction to other procedures performed in that session.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. CMS does not permit co-surgeon or team-surgery payment for this service.
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.
