Scarlet fever (A38)

ICD-10 code A38 covers scarlet fever, a bacterial illness commonly linked to a streptococcal infection. These codes categorize scarlet fever cases by the presence or absence of specific complications, helping healthcare providers document and treat this condition accurately.

Scarlet fever is classified under several codes reflecting its clinical variations. A38.9 is used for uncomplicated scarlet fever, also known as streptococcal sore throat with scarlatina or Streptococcus pyogenes infection. When scarlet fever leads to complications, distinct codes apply: A38.0 indicates scarlet fever with otitis media (ear infection caused by the scarlet fever), while A38.1 covers scarlet fever complicated by myocarditis, an inflammation of the heart muscle. A38.8 is reserved for scarlet fever with other complications, sometimes called staphylococcal scarlatina. Using these specific ICD-10 codes ensures clear communication about the patient's condition and guides appropriate medical care.
