Other codes that can never be billed with Q74.3
These codes carry an Excludes1 note pointing at Q74.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q74.3 alone.
- G72Other and unspecified myopathies
Risk adjustment
Q74.3 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.
How Q74.3 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to Q74.3.
