About coding Pseudomuscular hypertrophy
The ICD-10-CM code for Pseudomuscular hypertrophy is G71.09 (Other specified muscular dystrophies).
Within G71.0, choose G71.09 (Other specified muscular dystrophies) only when documentation doesn't support a more specific option: unspecified (G71.00), Duchenne or Becker muscular dystrophy (G71.01), Facioscapulohumeral muscular dystrophy (G71.02) and limb girdle muscular dystrophies (G71.03).
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.
