- Billable — Valid for Submission
- Chronic Condition
E85.0 is a billable ICD-10-CM diagnosis code for non-neuropathic heredofamilial amyloidosis. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 545 through 547. Coders also document this condition as cardiac familial non-neuropathic amyloidosis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified and unspecified nutritional and metabolic disorders.

Tabular List NotesGuidance
Coding notes and annotation back-references applicable to this code.
Inclusion Terms
- Hereditary amyloid nephropathy
Code Also
- associated disorders, such as:
- autoinflammatory syndromes M04
Type 2 Excludes
- Transthyretin-related ATTR familial amyloid cardiomyopathy E85.4
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical ClassificationClinical
AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
Amyloid Neuropathies, Familial
inherited disorders of the peripheral nervous system associated with the deposition of amyloid in nerve tissue. the different clinical types based on symptoms correspond to the presence of a variety of mutations in several different proteins including transthyretin (prealbumin); apolipoprotein a-i; and gelsolin.Amyloidosis
a group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of amyloid. as the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. various signs and symptoms depend on the location and size of the deposits.Amyloidosis, Familial
diseases in which there is a familial pattern of amyloidosis.Cerebral Amyloid Angiopathy, Familial
a familial disorder marked by amyloid deposits in the walls of small and medium sized blood vessels of cerebral cortex and meninges.Immunoglobulin Light-chain Amyloidosis
a nonproliferative disorder of plasma cells characterized by excessive production and misfolding of immunoglobulin light chains that form insoluble amyloid fibrils (see amyloid deposits) in various tissues. clinical features include liver failure; multiple myeloma; nephrotic syndrome; restrictive cardiomyopathy, and neuropathies.Amyloid
a fibrous protein complex that consists of proteins folded into a specific cross beta-pleated sheet structure. this fibrillar structure has been found as an alternative folding pattern for a variety of functional proteins. deposits of amyloid in the form of amyloid plaques are associated with a variety of degenerative diseases. the amyloid structure has also been found in a number of functional proteins that are unrelated to disease.
Patient EducationClinical
Amyloidosis
Amyloidosis occurs when abnormal proteins called amyloids build up and form deposits. The deposits can collect in organs such as the kidney and heart. This can cause the organs to become stiff and unable to work the way they should.

Questions About E85.0Overview
Is E85.0 (Amyloidosis) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report non-neuropathic heredofamilial amyloidosis on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does E85.0 group to?
When non-neuropathic heredofamilial amyloidosis is the principal diagnosis on an inpatient stay, it groups to MS-DRG 545, 546, 547, with relative weights from 0.8362 to 2.4817 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of E85.0?
Under the General Equivalence Mappings, non-neuropathic heredofamilial amyloidosis converts to ICD-9-CM 277.31 (fam Mediterranean fever). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:
- The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
- The condition places limitations on self-care, independent living, and social interactions.
