Is Q74 a billable ICD-10-CM code?

No. Q74 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does Q74 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 Q74?

Q74 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

Q74

Q74 — Other congenital malformations of limb(s)

Non-billable headerICD-10-CM

Q74 is a non-billable header ICD-10-CM code for other congenital malformations of limb(s). It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

polydactyly (Q69.-)
reduction defect of limb (Q71-Q73)
syndactyly (Q70.-)

Other codes that can never be billed with Q74

These codes carry an Excludes1 note pointing at Q74. 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 alone.

M20Acquired deformities of fingers and toes
M21Other acquired deformities of limbs
G72Other and unspecified myopathies

Risk adjustment

Q74 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 to one of these instead Q74

6 child codes. Green means billable.
