ICD-10 Code E85.89 – Other amyloidosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E85.89 – Other amyloidosis
What it is
E85.89 identifies amyloidosis that does not fit a more specific ICD-10-CM amyloidosis category. It means abnormal protein deposits are documented, but the record does not name a different coded type.
Clinical signs
Clinical features vary; refer to documentation. Amyloidosis may involve one or more organs, and the chart should describe the affected site, type if known, or related manifestations.
When to use this code
Use this code when the provider documents amyloidosis and no more specific amyloid type is stated or applicable. It also fits cases where the record says “other amyloidosis” or describes an amyloid disorder outside the listed categories. Check documentation if the type is unclear.
Do not use for
Do not use this code when the record supports a more specific amyloidosis code, such as another named subtype. Do not assign it for suspected amyloidosis without confirmed documentation.
Coding tip
If the note is nonspecific, query for the amyloid type and involved organ before assigning E85.89.
