Is Q75.05 a billable ICD-10-CM code?

No. Q75.05 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does Q75.05 sit in the tabular list?

Congenital malformations, deformations and chromosomal abnormalities (Q00-QA0), in the block Congenital malformations and deformations of the musculoskeletal system (Q65-Q79).

What cannot be coded together with Q75.05?

Q75.05 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above Q75.05 (Q75) and apply to it just the same.

Q75.05

Q75.05 — Multi-suture craniosynostosis

Non-billable headerICD-10-CM

Q75.05 is a non-billable header ICD-10-CM code for multi-suture craniosynostosis. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 inherited from the categories above Q75.05

These are not written on Q75.05, but they bind it: a note on a category applies to every code beneath it. Billing Q75.05 with anything listed here is a denial.

Written on Q75 — Other congenital malformations of skull and face bones

congenital malformation of face NOS (Q18.-)
congenital malformation syndromes classified to Q87.-
dentofacial anomalies [including malocclusion] (M26.-)
musculoskeletal deformities of head and face (Q67.0-Q67.4)
skull defects associated with congenital anomalies of brain such as:
anencephaly (Q00.0)
encephalocele (Q01.-)
hydrocephalus (Q03.-)
microcephaly (Q02)

Other codes that can never be billed with Q75.05

These codes carry an Excludes1 note pointing at Q75.05. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q75.05 alone.

Risk adjustment

Q75.05 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

Q75.05 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead Q75.05

3 child codes. Green means billable.
