ICD-10 Code A48.5 – Other specified botulism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A48.5 – Other specified botulism
What it is
A48.5 identifies a botulism diagnosis that does not fit the standard named categories. Use it when documentation clearly states another specified form of botulism or a related botulinum toxin illness.
Clinical signs
Clinical features vary; refer to documentation. Botulism typically presents with cranial nerve findings, such as blurred vision, drooping eyelids, or difficulty speaking, followed by descending weakness.
When to use this code
Use this code when the provider documents botulism but specifies a type not captured by another ICD-10-CM code. It may apply when the record names an uncommon exposure or presentation and clearly supports botulism. If the chart is nonspecific, check documentation before coding.
Do not use for
Do not use A48.5 for unspecified botulism when no further detail is given. Also avoid it when the condition is better described by a different infectious or toxin-related diagnosis.
Coding tip
Code the documented botulism type exactly as stated and verify that the record supports a specific “other” category.
