ICD-10 Code J93.83 – Other pneumothorax (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J93.83 – Other pneumothorax
What it is
Other pneumothorax means air is present in the pleural space, causing partial or complete lung collapse, but the record does not fit a more specific pneumothorax code. Use this when documentation identifies pneumothorax without a better-defined subtype.
Clinical signs
Common findings include sudden pleuritic chest pain, shortness of breath, and reduced breath sounds on the affected side. Clinical features vary; refer to documentation and imaging confirmation when available.
When to use this code
Use J93.83 when the provider documents pneumothorax and specifies it as other, atypical, or not otherwise classifiable. It may also fit when the chart confirms pneumothorax but does not support a more specific code. Check documentation if the cause, type, or laterality is unclear.
Do not use for
Do not use this code for traumatic, iatrogenic, tension, or spontaneous pneumothorax when a more specific code is documented. If the note identifies a different pleural air condition, code that diagnosis instead.
Coding tip
Verify the provider’s exact wording and code the most specific pneumothorax type documented.
