ICD-10 code for Hydromyelia

The ICD-10-CM code for Hydromyelia is Q06.4 (Hydromyelia).

Within Q06 (other congenital malformations of spinal cord), Q06.4 is specifically for Hydromyelia. Related codes cover Amyelia (Q06.0), hypoplasia and dysplasia of spinal cord (Q06.1), Diastematomyelia (Q06.2), other congenital cauda equina malformations (Q06.3), other specified congenital malformations of spinal cord (Q06.8) and congenital malformation of spinal cord, unspecified (Q06.9).

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), DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), 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.
