What This Code Means

A congenital narrowing of the pulmonary artery where the vessel is pinched or constricted at a specific point, reducing blood flow to the lungs.

Coding Tips

•Distinguish between central coarctation and peripheral pulmonary artery stenosis
•Document any associated right ventricular hypertrophy or hemodynamic compromise

Clinical Significance

Coarctation of the pulmonary artery creates obstruction to pulmonary blood flow, potentially leading to right heart strain, arrhythmias, and exercise intolerance. This condition requires ongoing cardiology management and may need interventional or surgical correction.

Documentation Requirements

✓Echocardiographic evidence of pulmonary artery narrowing
✓Doppler flow measurements across the stenotic area
✓Assessment of right ventricular function and pressures
✓Exercise tolerance and functional capacity assessment
✓Associated congenital heart defects documentation
✓Cardiac catheterization results if performed
✓Treatment recommendations (balloon angioplasty, surgery)
✓Long-term monitoring and follow-up plans

Commonly Confused Codes

Q25.1 — Coarctation of aorta (aortic coarctation, more common condition)Q25.5 — Atresia of pulmonary artery (complete closure, not narrowing)Q22.1 — Congenital pulmonary valve stenosis (valve level stenosis)Q25.79 — Other congenital malformations of pulmonary artery (less specific)
