Neurodevelopmental disorders related to pathogenic variants in certain specific genes
Congenital Malformations, Deformations and Chromosomal Abnormalities·Neurodevelopmental disorders related to pathogenic variants in specific genes·subcategory·FY 2027
12 billable codes under QA0.01: all are a CC; none map to an HCC.A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment.
Instructional notes
Also applies, from QA0: Neurodevelopmental disorders related to specific genetic pathogenic variants
These notes sit on QA0 and apply to every code under it, including QA0.01.
Code also: add a code for this too, order depends on the encounter

MS-DRGs
As the principal diagnosis, all 12 billable codes under QA0.01 group to these MS-DRGs (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.
