About coding spastic paralysis
The ICD-10-CM code for spastic paralysis is G83.9 (Paralytic syndrome, unspecified). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G83.9.
Within G83, choose G83.9 (Paralytic syndrome, unspecified) only when documentation doesn't support a more specific option: diplegia of upper limbs (G83.0), monoplegia of lower limb (G83.1), monoplegia of upper limb (G83.2), monoplegia, unspecified (G83.3), cauda equina syndrome (G83.4), Locked-in state (G83.5) and other specified paralytic syndromes (G83.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 091 (Other Disorders of Nervous System with MCC, relative weight 1.7046), DRG 092 (Other Disorders of Nervous System with CC, relative weight 1.0239) and DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
