A65Nonvenereal syphilis

Billable / specific codeICD-10-CM

A65 is a billable, specific ICD-10-CM code for nonvenereal syphilis. It is valid for submission on a claim.

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Bejel
  • Endemic syphilis
  • Njovera

Risk adjustment

A65 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 A65 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 A65.

  • Bejel
  • Dichuchwa
  • Njovera
  • Siti
  • Skerljevo
  • Syphilis, syphiliticendemic
  • Syphilis, syphiliticnonvenereal
