About Q05.3

Q05.3 is the ICD-10-CM diagnosis code for sacral spina bifida with hydrocephalus. It belongs to category Q05 (spina bifida), 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 Q05 (spina bifida), Q05.3 is specifically for sacral spina bifida with hydrocephalus. Related codes cover cervical spina bifida with hydrocephalus (Q05.0), thoracic spina bifida with hydrocephalus (Q05.1), lumbar spina bifida with hydrocephalus (Q05.2), unspecified spina bifida with hydrocephalus (Q05.4), cervical spina bifida without hydrocephalus (Q05.5), thoracic spina bifida without hydrocephalus (Q05.6), lumbar spina bifida without hydrocephalus (Q05.7), sacral spina bifida without hydrocephalus (Q05.8) and 1 more.

Use an additional code for any associated paraplegia (paraparesis) (G82.2-).

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 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 741.03 (spina bifida with hydrocephalus, lumbar region).
