About coding leg paralysis

The ICD-10-CM code for leg paralysis is G83.1 (Monoplegia of lower limb). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G83.1.

Within G83 (other paralytic syndromes), G83.1 is specifically for monoplegia of lower limb. Related codes cover diplegia of upper limbs (G83.0), monoplegia of upper limb (G83.2), monoplegia, unspecified (G83.3), cauda equina syndrome (G83.4), Locked-in state (G83.5), other specified paralytic syndromes (G83.8) and paralytic syndrome, unspecified (G83.9).

To report this condition, pick the subcode that matches the documentation: G83.10 (affecting unspecified side), G83.11 (affecting right dominant side), G83.12 (affecting left dominant side), G83.13 (affecting right nondominant side) and G83.14 (affecting left nondominant side).

Don't report G83.1 together with the conditions in its Excludes1 note: monoplegia of lower limbs due to sequela of cerebrovascular disease (I69.04-, I69.14-, I69.24-, I69.34-, I69.84-, I69.94-).
