ICD-10 Code J95.812 – Postprocedural air leak (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J95.812 – Postprocedural air leak
What it is
J95.812 identifies an air leak that occurs after a procedure, usually when air escapes from the lung, airway, or surgical site. Use it when the record specifically links the leak to a prior procedure.
Clinical signs
Clinical features may include persistent bubbling in a chest drain, subcutaneous emphysema, or imaging evidence of air outside the expected space. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a postprocedural air leak as a complication of surgery or another invasive procedure. It fits cases where the leak is clearly identified and attributed to the procedure. If the note only mentions a pneumothorax or other complication without stating an air leak, check documentation.
Do not use for
Do not use this code for air leak that is present before the procedure or unrelated to the procedure. Do not use it when the chart does not clearly document a postprocedural air leak.
Coding tip
Code J95.812 only when the complication is explicitly documented as postprocedural and supported by the operative or progress note.
