Pain, not elsewhere classified (G89) ICD-10-CM
The G89 code range covers pain, not elsewhere classified with 13 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code Also
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
- related psychological factors associated with pain F45.42
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- generalized pain NOS R52
- pain disorders exclusively related to psychological factors F45.41
- pain NOS R52
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the G89 range.
Breakthrough Pain
Acute pain that comes on rapidly despite the use of pain medication.
Chronic Pain
Aching sensation that persists for more than a few months. It may or may not be associated with trauma or disease, and may persist after the initial injury has healed. Its localization, character, and timing are more vague than with acute pain.
About the G89 Code Range
ICD-10 code G89 covers categories of pain that do not fit into other specific classifications. These codes describe various types of pain, including acute, chronic, central, postprocedural, and neoplasm-related pain.
This section is used to accurately code and document pain conditions like central pain syndrome (G89.0), also known as central neuropathic pain or thalamic pain, which arises from nerve damage within the central nervous system. Acute pain, not elsewhere classified (G89.1), includes trauma-related pain (G89.11) and acute post-thoracotomy pain (G89.12). Postprocedural pain codes (G89.18 and G89.28) cover pain after surgeries such as mastectomy or hernia repair. Chronic pain codes (G89.2 series) address ongoing pain due to trauma, surgery, or other causes, including chronic post-thoracotomy pain (G89.22) and generalized chronic pain (G89.29), covering conditions like chronic back pain and neuropathic pain. The section also recognizes pain from neoplasms (G89.3) and chronic pain syndrome (G89.4).
