About coding lumbosacral spina bifida
The ICD-10-CM code for lumbosacral spina bifida is Q05.7 (Lumbar spina bifida without hydrocephalus). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q05.7.
Within Q05, choose Q05.7 (Lumbar spina bifida without hydrocephalus) 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), sacral spina bifida without hydrocephalus (Q05.8) 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.
