ICD-10 Code G89.0 – Central pain syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G89.0 – Central pain syndrome
What it is
G89.0 identifies central pain syndrome, a chronic pain condition caused by injury or dysfunction in the central nervous system. You use it when documentation specifically links pain to a central neurologic source.
Clinical signs
Clinical features vary; refer to documentation. Typical records describe persistent pain with neurologic findings after a brain or spinal cord lesion, and the pain is often difficult to localize or explain by peripheral injury.
When to use this code
Use this code when the provider documents central pain syndrome, central neuropathic pain, or pain attributed to a central nervous system disorder. It may appear after stroke, spinal cord injury, or other central neurologic disease if the pain is clearly documented as central in origin.
Do not use for
Do not use this code for ordinary acute pain, peripheral neuropathic pain, or pain without a documented central cause. Check documentation if the record only says “pain” or gives an unclear neurologic source.
Coding tip
Code G89.0 only when the chart explicitly states central pain syndrome or an equivalent central pain diagnosis.
