ICD-10 Code J81.0 – Acute pulmonary edema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J81.0 – Acute pulmonary edema
What it is
J81.0 identifies acute pulmonary edema, a sudden buildup of fluid in the lungs. It is used when documentation shows an acute episode of pulmonary fluid accumulation causing respiratory distress.
Clinical signs
Typical findings include acute shortness of breath, cough, and crackles on lung exam. Clinical features vary; refer to documentation for the cause and supporting imaging or exam findings.
When to use this code
Use this code when the provider documents acute pulmonary edema as the diagnosis. It may be appropriate in emergency or inpatient records when the condition is clearly stated and not described only as chronic fluid overload. Check documentation if the cause is specified separately.
Do not use for
Do not use J81.0 for chronic pulmonary edema or generalized edema without lung involvement. If the record does not clearly support an acute pulmonary edema diagnosis, check documentation.
Coding tip
Code the documented acute condition exactly as stated and capture any underlying cause when separately reported.
