Includes

Conditions this code covers.

  • infection or foodborne intoxication due to any Salmonella species other than S. typhi and S. paratyphi

Other codes that can never be billed with A02

These codes carry an Excludes1 note pointing at A02. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A02 alone.

  • A05Other bacterial foodborne intoxications, not elsewhere classified
  • M86Osteomyelitis
  • M90Osteopathies in diseases classified elsewhere
  • N16Renal tubulo-interstitial disorders in diseases classified elsewhere
  • J17Pneumonia in diseases classified elsewhere

Risk adjustment

A02 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 A02

5 child codes. Green means billable.
