ICD-10 code for tropical spastic paraplegia

The ICD-10-CM code for tropical spastic paraplegia is G04.1 (Tropical spastic paraplegia).

Within G04 (encephalitis, myelitis and encephalomyelitis), G04.1 is specifically for tropical spastic paraplegia. Related codes cover acute disseminated encephalitis and encephalomyelitis (ADEM) (G04.0), bacterial meningoencephalitis and meningomyelitis, not elsewhere classified (G04.2), acute necrotizing hemorrhagic encephalopathy (G04.3), other encephalitis, myelitis and encephalomyelitis (G04.8) and unspecified (G04.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 052 (Spinal Disorders and Injuries with CC/MCC, relative weight 1.7837) and DRG 053 (Spinal Disorders and Injuries without CC/MCC, relative weight 0.9728), 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.
