About Q06.9
Q06.9 is the ICD-10-CM diagnosis code for congenital malformation of spinal cord, unspecified. It belongs to category Q06 (other congenital malformations of spinal cord), block Q00-Q07 (congenital malformations of the nervous system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Q06, choose Q06.9 (Congenital malformation of spinal cord, unspecified) only when documentation doesn't support a more specific option: Amyelia (Q06.0), hypoplasia and dysplasia of spinal cord (Q06.1), Diastematomyelia (Q06.2), other congenital cauda equina malformations (Q06.3), Hydromyelia (Q06.4) and other specified congenital malformations of spinal cord (Q06.8).
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.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 742.59 (other specified congenital anomalies of spinal cord) and 742.9 (unspecified congenital anomaly of brain, spinal cord, and nervous system).
