ICD-10-CM FY2027 addition
QA1.7 ICD-10-CM Code: Inherited neoplasm predisposition syndromes involving multiple systems, not elsewhere classified
New for FY2027: effective October 1, 2026
QA1.7 is one of the 238 entries the FY2027 order file adds. It is not reportable for dates of service before October 1, 2026.
Risk adjustment status: the PY2027 Initial ICD-10-CM mapping does not list this code, so no HCC or coefficient is shown. A later CMS mapping file must pass source verification before a mapping appears here.

Frequently asked questions
When can QA1.7 be reported?
QA1.7 (Inherited neoplasm predisposition syndromes involving multiple systems, not elsewhere classified) is new in the FY2027 ICD-10-CM code set, effective October 1, 2026. It applies to dates of service on or after that date; it is not valid in the FY2026 set that runs through September 30, 2026.
Is QA1.7 a billable code?
No. QA1.7 is a header in the FY2027 order file; it needs a further character. Report the specific child code the FY2027 tabular lists beneath it.
Does QA1.7 map to an HCC?
Not yet known from a verified source. The PY2027 Initial ICD-10-CM mapping file does not list QA1.7, so HCC Buddy shows no HCC category or coefficient for it. A later CMS mapping file must pass source verification before a mapping appears on this page.
Is QA1 7 the same code as QA1.7?
Yes. QA1 7 and QA17 are the same code written without the decimal; the ICD-10-CM form is QA1.7.
