ICD-10 Code G89.22 – Chronic post-thoracotomy pain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G89.22 – Chronic post-thoracotomy pain
What it is
G89.22 identifies long-lasting pain that remains after a thoracotomy, meaning an incision through the chest wall. Use it when the pain is documented as chronic and linked to the prior surgery.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record describes persistent chest wall pain at or near the surgical site, often lasting beyond normal healing and affecting daily function.
When to use this code
Use this code when the provider documents chronic pain following thoracotomy and indicates it is not expected postoperative discomfort. Code it for ongoing pain management visits, follow-up evaluations, or problem lists tied to the prior chest surgery. Check documentation for laterality, if relevant.
Do not use for
Do not use this code for acute postoperative pain, unspecified chest pain, or pain from another cause. If the note does not clearly link the pain to a prior thoracotomy, check documentation.
Coding tip
Confirm the pain is chronic and post-thoracotomy before assigning G89.22.
