A50.2 — Early congenital syphilis, unspecified
A50.2 is a billable, specific ICD-10-CM code for early congenital syphilis, unspecified. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Congenital syphilis NOS less than two years after birth.
Other codes that can never be billed with A50.2
These codes carry an Excludes1 note pointing at A50.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A50.2 alone.
- A53.9Syphilis, unspecified
Risk adjustment
A50.2 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 A50.2 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 A50.2.
- Syphilis, syphilitic›congenital›early, or less than 2 years after birth NEC
