ICD-10 Code B05.8 – Measles with other complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B05.8 – Measles with other complications
What it is
B05.8 identifies measles when the infection is documented with complications not captured by more specific measles codes. Use it for confirmed measles cases with an additional complication noted in the record.
Clinical signs
Measles typically presents with fever, cough, coryza, conjunctivitis, and a characteristic rash. Clinical features vary; refer to documentation for the specific complication that supports this code.
When to use this code
Use B05.8 when the provider documents measles plus another complication and no more specific measles code applies. The chart should clearly link the complication to measles, such as a documented measles-related complication. If the record only says measles without complications, choose a different code.
Do not use for
Do not use this code for uncomplicated measles or when the complication is separately coded under a more specific measles category. Check documentation if the record does not clearly identify a measles-related complication.
Coding tip
Confirm that the complication is explicitly documented as associated with measles before assigning B05.8.
