About coding meningocele anomaly
The ICD-10-CM code for meningocele anomaly is Q05.9 (Spina bifida, unspecified).
Within Q05, choose Q05.9 (unspecified) only when documentation doesn't support a more specific option: cervical spina bifida with hydrocephalus (Q05.0), thoracic spina bifida with hydrocephalus (Q05.1), lumbar spina bifida with hydrocephalus (Q05.2), sacral spina bifida with hydrocephalus (Q05.3), 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) and 1 more.
Use an additional code for any associated paraplegia (paraparesis) (G82.2-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
