ICD-10 Code G89.2 – Chronic pain, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G89.2 – Chronic pain, not elsewhere classified
What it is
G89.2 identifies chronic pain that is documented as a distinct diagnosis and does not fit a more specific pain category. Use it when the record describes ongoing pain without a clearer underlying code.
Clinical signs
Clinical features vary; refer to documentation. Chronic pain is typically persistent or recurrent pain lasting longer than expected for normal healing and may affect function, sleep, mood, or daily activities.
When to use this code
Use G89.2 when the provider documents chronic pain and does not name a more specific pain type or cause. It may apply when pain is the primary focus of care or is recorded as an active diagnosis. If the chart links the pain to a specific condition, code the underlying condition first when appropriate.
Do not use for
Do not use this code for acute pain, postoperative pain, or pain with a clearly documented specific site or cause that has a more precise code. Check documentation.
Coding tip
Code the pain only when it is explicitly documented as chronic and not better captured by a more specific diagnosis.
