What 33419 covers
This add-on represents an additional repair implant, commonly a clip, placed during a percutaneous transcatheter mitral valve repair for mitral regurgitation. The procedure is typically performed by an interventional cardiologist or cardiac surgeon in a catheterization laboratory or hybrid suite, with imaging guidance. The initial prosthesis is reported with the primary transcatheter repair service; this code captures an additional prosthesis placed during that repair.
Report one unit for each additional prosthesis supported by the operative record. Documentation should identify the transcatheter approach, the repair performed, and the number of prostheses placed. Do not count device repositioning or leaflet-grasp attempts as additional prostheses. This is an add-on code: report it only with its primary procedure, 33418, and CMS pays it within that procedure’s global period.

33419 billing questions
When should 33419 be reported instead of 33418?
33418 reports the initial prosthesis used in the transcatheter mitral repair. Report 33419 for each additional prosthesis placed during that repair.
Can 33419 be submitted without 33418?
No. It is an add-on code and must be reported with the primary transcatheter mitral repair procedure, 33418.
How many units should be reported?
Report one unit for each prosthesis beyond the initial one. Device repositioning or repeated grasping attempts do not represent additional prostheses.
What documentation supports the additional unit?
The procedural record should establish the transcatheter mitral repair and document the number of prostheses placed, including the additional device or devices.
How does this differ from open mitral repair?
33419 applies to an additional prosthesis during percutaneous transcatheter repair. Codes such as 33425 and 33427 describe open surgical mitral repair procedures.
