ICD-10 code for persistent vegetative state

The ICD-10-CM code for persistent vegetative state is R40.3 (Persistent vegetative state).

Within R40 (Somnolence, stupor and coma), R40.3 is specifically for persistent vegetative state. Related codes cover Somnolence (R40.0), stupor (R40.1), coma (R40.2) and transient alteration of awareness (R40.4).

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 080 (Nontraumatic Stupor and Coma with MCC, relative weight 1.7472), DRG 081 (Nontraumatic Stupor and Coma without MCC, relative weight 0.806), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 01 (Diseases and Disorders of the Nervous System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
