ICD-10-PCS Code For Mitral Valve: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 02BG includes procedures performed to excise portions of the mitral valve in the heart and great vessels. These ICD-10-PCS codes are used for inpatient documentation when a portion of the mitral valve is surgically removed without replacement. Accurate coding within the ICD-10-PCS 02BG group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and determines appropriate case mix and payment.

Typical Clinical Scenarios

A 62-year-old patient with progressive symptomatic mitral valve regurgitation due to focal leaflet prolapse presents electively for surgical management after failing medical therapy; the surgeon plans removal of a flail segment of the posterior mitral leaflet via an open sternotomy without valve replacement to relieve regurgitation and preserve native valve function. Typical codes: 02BG0ZZ.
An 82-year-old frail patient with bacterial endocarditis causing a localized destructive lesion of the mitral valve leaflets is admitted urgently with sepsis and heart failure; the operative team performs a limited percutaneous excision of the infected tissue to control infection and stabilize hemodynamics when full valve replacement is not immediately feasible. Typical codes: 02BG3ZZ.
A 45-year-old patient with prior mitral valve repair develops recurrent obstruction from scar tissue months after the index operation and is taken to the OR for minimally invasive percutaneous endoscopic resection of obstructing fibrous tissue on the mitral valve to relieve stenosis and improve valve mobility. Typical codes: 02BG4ZZ, 02BG4ZX
