Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Sperm count following sterilization reversal
Other codes that can never be billed with Z31.42
These codes carry an Excludes1 note pointing at Z31.42. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z31.42 alone.
Risk adjustment
Z31.42 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.
