Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Any congenital syphilitic condition specified as late or manifest two years or more after birth.
Other codes that can never be billed with A50.5
These codes carry an Excludes1 note pointing at A50.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A50.5 alone.
Risk adjustment
A50.5 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 A50.5
