ICD-10-PCS Code For Papillary Muscle: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 028D includes procedures performed to divide papillary muscle tissue in the heart and great vessels. These ICD-10-PCS codes are used for inpatient documentation when papillary muscle division is performed to correct structural issues, facilitate repair, or provide surgical access during cardiac procedures. Accurate coding within the ICD-10-PCS 028D group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and supports clinical documentation accuracy.

Papillary Muscle Division Procedure Overview

Procedures in ICD-10 PCS 028D involve division of papillary muscle tissue within the heart and great vessels. These procedures separate or transect papillary muscle tissue as part of cardiac surgical treatment for structural abnormalities or access to intracardiac structures. Accurate coding identifies the specific division of papillary muscle and supports correct inpatient payment and clinical recordkeeping.

When to Use

Use a code from this group when the papillary muscle is deliberately separated or transected as the primary action during an inpatient cardiac procedure. Do not use these codes for other cardiac procedures where division of papillary muscle is incidental and not documented as the operative intent.

Typical Clinical Scenarios

A patient presents emergently with acute severe mitral regurgitation after papillary muscle rupture secondary to an inferior-wall myocardial infarction. In the setting of hemodynamic instability and pulmonary edema, the cardiac surgery team performs an open surgical procedure to divide and resect the disrupted papillary muscle tissue to allow definitive repair or valve replacement. This inpatient intervention is undertaken urgently to correct the mechanical complication and stabilize the patient. Typical codes: 028D0ZZ
An elective mitral valve repair is planned for a patient with chronic degenerative mitral regurgitation due to tethering of the papillary muscles causing leaflet dysfunction. During the scheduled open-heart procedure, deliberate division of a papillary muscle is performed to facilitate leaflet mobility and permit durable valve repair. The patient is admitted electively for the inpatient surgical repair and postoperative monitoring. Typical codes: 028D0ZZ
A patient with recurrent symptomatic mitral valve dysfunction after prior percutaneous interventions undergoes a percutaneous endoscopic-assisted procedure to selectively divide restrictive papillary muscle tissue that is contributing to recurrent leaflet restriction. This inpatient procedure is performed to improve valve function as an alternative to repeat open surgery, addressing the complication of prior interventions while the patient remains hospitalized for observation. Typical codes: 028D3ZZ, 028D4ZZ
