ICD-10 Code B94.8 – Sequelae of other specified infectious and parasitic diseases (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B94.8 – Sequelae of other specified infectious and parasitic diseases
What it is
B94.8 identifies late effects that remain after an infectious or parasitic disease not otherwise classified elsewhere. Use it when the current problem is a residual condition, not an active infection.
Clinical signs
Clinical features vary; refer to documentation. You may see persistent organ damage, neurologic deficits, scarring, or other residual findings linked to a prior infection or parasite exposure.
When to use this code
Use this code when the record clearly states a sequela from a past infectious or parasitic illness and no more specific sequela code applies. It supports coding of the lingering condition, such as chronic impairment or residual symptoms, when the original infection is no longer active. Check documentation for the causal relationship.
Do not use for
Do not use B94.8 for an active infection, an uncertain history alone, or a sequela that has a more specific ICD-10-CM code. If the residual effect is not documented, check documentation.
Coding tip
Code the residual condition first when documented, and add B94.8 only to show the prior infectious cause.
