Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Accessory carpal bones
- Cleidocranial dysostosis
- Congenital pseudarthrosis of clavicle
- Macrodactylia (fingers)
- Madelung's deformity
- Radioulnar synostosis
- Sprengel's deformity
- Triphalangeal thumb
Excludes1 inherited from the categories above Q74.0
These are not written on Q74.0, but they bind it: a note on a category applies to every code beneath it. Billing Q74.0 with anything listed here is a denial.
Other codes that can never be billed with Q74.0
These codes carry an Excludes1 note pointing at Q74.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q74.0 alone.
- M20Acquired deformities of fingers and toes
Risk adjustment
Q74.0 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.
Medicare coverage
Q74.0 is named in 2 Medicare coverage policies — 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
