ICD Code E85.4

ICD code E85.4 is organ-limited amyloidosis, which refers to a condition where abnormal protein deposits (amyloid) are found in a specific organ without widespread involvement of other organs.

1. Evidence of amyloid deposits localized to a single organ, confirmed by biopsy or imaging

2. Absence of systemic involvement or multi-organ amyloid deposition

3. Clinical symptoms attributable to dysfunction of the affected organ (e.g., organ-specific pain, swelling, or impaired function)

4. Laboratory or histopathological confirmation of amyloid type consistent with organ-limited disease

5. Exclusion of hereditary, secondary, or systemic amyloidosis through appropriate diagnostic workup
