Official Coding Guidelines

Dominant/nondominant defaults for hemiplegia/monoplegia coding

Codes from category G81, Hemiplegia and hemiparesis, and subcategories G83.1, Monoplegia of lower limb, G83.2, Monoplegia of upper limb, and G83.3, Monoplegia, unspecified, identify whether the dominant or nondominant side is affected. Should the affected side be documented, but not specified as dominant or nondominant, and the classification system does not indicate a default, code selection is as follows: • For ambidextrous patients, the default should be dominant. • If the left side is affected, the default is non-dominant. • If the right side is affected, the default is dominant.
