ICD-10 Code G89.18 – Other acute postprocedural pain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G89.18 – Other acute postprocedural pain
What it is
G89.18 identifies acute pain that occurs after a procedure and is not otherwise classified. Use it when the record clearly links the pain to a recent surgery or intervention.
Clinical signs
Clinical features vary; refer to documentation. You may see localized postoperative pain, tenderness, or discomfort described as acute and procedure-related.
When to use this code
Use this code when the provider documents acute pain as a postprocedural complication or expected postoperative issue and no more specific pain code applies. It can support coding of pain that is clearly separate from the routine surgical diagnosis. Check documentation for the procedure type, timing, and whether the pain is acute.
Do not use for
Do not use it for chronic pain, unspecified pain, or pain unrelated to a procedure. If the pain is better described by another postoperative complication or by a different pain category, choose that code instead.
Coding tip
Verify that the note states the pain is acute and postprocedural before assigning G89.18.
