A38Scarlet fever

Non-billable headerICD-10-CM

A38 is a non-billable header ICD-10-CM code for scarlet fever. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • streptococcal sore throat (J02.0)

Includes

Conditions this code covers.

  • scarlatina

Other codes that can never be billed with A38

These codes carry an Excludes1 note pointing at A38. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A38 alone.

  • H67Otitis media in diseases classified elsewhere

Risk adjustment

A38 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 A38

4 child codes. Green means billable.
