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 027G includes procedures performed to dilate the mitral valve in the heart and great vessels. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs intraluminal dilation of the mitral valve to relieve stenosis or improve valve orifice size. Accurate coding within the ICD-10-PCS 027G group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Mitral Valve Dilation Procedure Overview

Procedures in this group involve dilating the mitral valve to expand its orifice and improve blood flow through the heart. These procedures target the heart and great vessels and use intraluminal dilation techniques applied to the mitral valve. Accurate ICD-10-PCS coding is important for inpatient reimbursement and for reflecting the clinical care delivered. Proper code selection supports documentation, case mix classification, and payment.

When to Use

Use a code from this group when a patient undergoes an intraluminal dilation procedure of the mitral valve during an inpatient stay. Typical clinical circumstances include treatment of mitral valve stenosis or when dilation is performed to address obstructive valve function.

Typical Clinical Scenarios

An elderly patient with symptomatic rheumatic mitral stenosis is admitted for planned inpatient intervention after progressive exertional dyspnea and reduced valve area on echocardiography. A percutaneous transseptal balloon dilation of the mitral valve is performed to increase the valve orifice and improve left atrial emptying. The procedure uses an intraluminal device delivered through the vasculature under imaging guidance during a scheduled admission. Typical codes: 027G3DZ, 027G3ZZ
A middle-aged patient presents emergently with acute pulmonary edema due to critical mitral stenosis and hemodynamic compromise. After stabilization, an urgent percutaneous endoscopic intraluminal dilation of the mitral valve is performed to rapidly relieve the obstruction and improve cardiac output. The approach is through the vasculature using endoscopic imaging to position the dilation device. Typical codes: 027G4DZ, 027G4ZZ
A patient with prior balloon mitral valvuloplasty who develops recurrent symptomatic stenosis undergoes a repeat intraluminal dilation to restore valve area. Because restenosis is present, a drug-eluting intraluminal device is selected during an open surgical exposure to reduce immediate recoil and attempt longer patency. The intervention is performed during an inpatient admission for reintervention. Typical codes: 027G04Z
