About QA1.7
QA1.7 is the ICD-10-CM diagnosis code for inherited neoplasm predisposition syndromes involving multiple systems, not elsewhere classified. It belongs to category QA1 (genetic disorders associated with neoplasms, not elsewhere classified), block QA0-QA1 (genetic disorders, not elsewhere classified) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: QA1.71 (syndrome) and QA1.79 (systems).
It was added in FY2027, effective October 1, 2026.
