ICD-10 Code G89.1 – Acute pain, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G89.1 – Acute pain, not elsewhere classified
What it is
G89.1 identifies acute pain that is not classified to a more specific site or cause. Use it when the record clearly documents acute pain, but the available details do not support a more precise code.
Clinical signs
Clinical features vary; refer to documentation. Acute pain is typically a recent onset, short-term pain complaint that may be associated with injury, inflammation, or another acute process.
When to use this code
Use this code when the provider documents acute pain and no more specific pain code is available. It may fit encounters focused on pain assessment when the cause or location is not fully established. Check documentation before assigning it.
Do not use for
Do not use it when the pain site, cause, or type is documented more specifically. Avoid it for chronic pain or pain that is better represented by another diagnosis. Check documentation.
Coding tip
Code the most specific pain diagnosis supported by the note, and use G89.1 only when specificity is lacking.
