ICD-10 · PDGM grouping
QA0 Neurodevelopmental disorders related to specific genetic pathogenic variants
All 13 codes in the QA0 family, with the PDGM clinical group, comorbidity subgroup and primary-position rule CMS assigns, read from the CMS grouper crosswalk v07.2.26 and the CDC FY2027 code file.

What CMS assigns to QA0
All 13 codes group to Neuro Rehabilitation. 3 of the 13 count toward the Epilepsy comorbidity subgroup; 10 are assigned none. Every code can lead a claim.
- Epilepsy: counts toward the high comorbidity tier only in an interaction pair.
