About coding Locked-in state
The ICD-10-CM code for Locked-in state is G83.5 (Locked-in state).
Within G83 (other paralytic syndromes), G83.5 is specifically for Locked-in state. Related codes cover 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), other specified paralytic syndromes (G83.8) and paralytic syndrome, unspecified (G83.9).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" 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 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.
