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.

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.

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.

Acute Pain

Intensely discomforting, distressful, or agonizing sensation associated with trauma or disease, with well-defined location, character, and timing.

Cancer Pain

Pain that may be caused by or related to cellular, tissue, and systemic changes that occur during NEOPLASM growth, tissue invasion, and METASTASIS.

Central Pain Syndrome

A neurological condition characterized by diffuse sensory changes, most commonly pain, secondary to central nervous system disease or injury.

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.

Pain

An unpleasant sensation induced by noxious stimuli which are detected by NERVE ENDINGS of NOCICEPTIVE NEURONS.

About the G89 Code Range

Pain that is not classified elsewhere appears here under nervous system disorders. The categories distinguish central pain syndrome, acute and chronic pain, pain related to a neoplasm (tumor), and chronic pain syndrome.

G89.0 identifies central pain syndrome. Acute pain under G89.1 and chronic pain under G89.2 split by cause or context: injury, thoracotomy (chest surgery), or another procedure. Chronic pain also has an other chronic pain subdivision. G89.3 identifies neoplasm-related pain, whether acute or chronic. G89.4 identifies chronic pain syndrome.
