ICD-10 Code J81.1 – Chronic Pulmonary Edema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J81.1 – Chronic pulmonary edema
What it is
J81.1 identifies chronic pulmonary edema, meaning persistent fluid accumulation in the lungs. Use it when the record specifically documents a chronic or ongoing edema pattern rather than an acute episode.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings may include shortness of breath, cough, and abnormal lung examination or imaging consistent with pulmonary fluid.
When to use this code
Use J81.1 when the provider clearly documents chronic pulmonary edema as the diagnosis. It may also apply when the condition is described as longstanding or recurrent and the note supports pulmonary fluid overload.
If the chart only states edema, fluid overload, or respiratory distress without confirming chronic pulmonary edema, check documentation before coding. Make sure the condition is not better represented by an acute or unspecified edema code.
Do not use for
Do not use this code for acute pulmonary edema or generalized edema elsewhere in the body. If the documentation is unclear, check documentation instead of assuming chronicity.
Coding tip
Code J81.1 only when the provider explicitly links the edema to the lungs and documents it as chronic.
