ICD-10 Code J95.1 – Acute pulmonary insufficiency following thoracic surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J95.1 – Acute pulmonary insufficiency following thoracic surgery
What it is
J95.1 identifies acute pulmonary insufficiency that develops after thoracic surgery. Use it when the postoperative record documents impaired breathing or inadequate lung function tied to the surgery.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe postoperative respiratory distress, hypoxemia, or need for increased oxygen support after thoracic procedures.
When to use this code
Use J95.1 when the surgeon or treating clinician clearly links acute pulmonary insufficiency to a thoracic operation. It fits postoperative cases where the respiratory problem is more than routine recovery and is specifically documented as a complication. Check documentation if the relationship to surgery is unclear.
Do not use for
Do not use this code for chronic lung disease, uncomplicated postoperative atelectasis, or respiratory issues not documented as acute pulmonary insufficiency. Check documentation when the chart only says shortness of breath.
Coding tip
Assign J95.1 only when the postoperative pulmonary insufficiency is explicitly linked to thoracic surgery in the provider note.
