ICD-10 Code A38.8 – Scarlet fever with other complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A38.8 – Scarlet fever with other complications
What it is
This code identifies scarlet fever when it includes complications not captured by a more specific code. It is used for a streptococcal illness with the classic scarlet fever diagnosis plus an additional documented complication.
Clinical signs
Typical scarlet fever findings include fever, sore throat, and a fine, sandpaper-like rash. Clinical features vary; refer to documentation for the specific complication, such as an associated inflammatory or infectious problem.
When to use this code
Use A38.8 when the provider documents scarlet fever and states another complication, but no more specific scarlet fever code fits. Confirm the complication is part of the record and not a separate, unrelated condition.
If the documentation only says scarlet fever without complications, choose the uncomplicated code instead. When the complication is clearly named and separately coded, follow official coding guidance and code each documented condition as appropriate.
Do not use for
Do not use this code for scarlet fever without complications or for nonspecific streptococcal pharyngitis alone. Check documentation if the record does not clearly identify a complication.
Coding tip
Query the provider when “other complications” is mentioned but the actual complication is not named.
