ICD-10 Code L50.8 – Other urticaria (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L50.8 – Other urticaria
What it is
Use this code for urticaria that does not fit the more specific ICD-10 categories. It describes recurrent wheals, hives, or similar allergic-appearing skin eruptions when the exact subtype is not documented.
Clinical signs
Typical findings include transient raised, itchy wheals that may change location over hours. Clinical features vary; refer to documentation if the record does not clearly describe the rash pattern or cause.
When to use this code
Assign L50.8 when the clinician documents “other urticaria,” “hives,” or a urticarial rash that is not otherwise specified. Use it when the note does not support a more specific code such as allergic, idiopathic, or physical urticaria. Check documentation if the cause is unclear.
Do not use for
Do not use this code for angioedema without urticaria or for a clearly documented, more specific urticaria type. If the rash is not urticarial, choose the condition that best matches the documented diagnosis.
Coding tip
Verify the provider’s exact wording, because “hives” alone often supports L50.8 only when no specific subtype is stated.
