Official coding guidelines
From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.
- Section I.C.6.b Pain - Category G89 (page 45), covers G89
Do not use G89 when pain is not acute, chronic, postoperative, or neoplasm-related, or when the definitive diagnosis is known, unless the encounter is for pain control. G89 is sequenced first only for pain management encounters.

About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
Pain
Pain is a signal in your nervous system that something may be wrong. It is an unpleasant feeling, such as a prick, tingle, sting, burn, or ache. Each person feels pain differently, even if the reason for the pain is the same. Pain may be sharp or dull. It may be mild or severe. Pain may come and go, or it may be constant. You may feel pain in one area of your body, such as your back, abdomen, chest, or pelvis, or you may feel it all over.
