ICD-10 Code G89.21 – Chronic pain due to trauma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G89.21 – Chronic pain due to trauma
What it is
G89.21 identifies chronic pain that persists after an injury or trauma. Use it when the record clearly links ongoing pain to a prior traumatic event.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see persistent pain lasting beyond expected healing, with a documented history of trauma and ongoing pain management needs.
When to use this code
Use this code when the provider documents chronic pain as due to a past injury, such as a fracture, crush injury, or other trauma. It fits situations where pain continues after the acute phase has resolved. Code the trauma itself separately when appropriate and supported by the record.
Do not use for
Do not use this code for acute pain, pain without a documented traumatic cause, or generalized chronic pain with no clear post-traumatic link. Check documentation if the cause is uncertain.
Coding tip
Assign G89.21 only when the chart explicitly connects the pain to prior trauma.
