ICD10 code of Familial Mediterranean Fever and ICD9 code

Familial Mediterranean Fever (FMF) is classified under the ICD-10-CM code E85.0 (hereditary amyloid nephropathy, which encompasses FMF) and was historically categorized under the ICD-9-CM code 277.31. These codes are essential for medical billing, insurance authorization for treatments like colchicine, and tracking the clinical progression of Familial Mediterranean Fever within healthcare systems.

What is the clinical significance of the ICD codes for Familial Mediterranean Fever?

In the medical community, the ICD-10 code E85.0 serves as the primary diagnostic identifier for Familial Mediterranean Fever. Because FMF is a systemic autoinflammatory disorder, accurate coding is vital to ensure that patients receive appropriate coverage for lifelong therapies, particularly colchicine, which is the gold standard of care. At DiseaseMaps.org, 264 people with Familial Mediterranean Fever have shared their experiences, highlighting how these standardized codes help clinicians advocate for consistent care and specialized monitoring for complications like secondary amyloidosis.

How is Familial Mediterranean Fever genetically inherited?

Familial Mediterranean Fever is an autosomal recessive disorder caused by mutations in the MEFV gene, located on the short arm of chromosome 16. This gene encodes a protein called pyrin, which plays a crucial role in regulating the body's inflammatory response. When the MEFV gene is mutated, the inflammatory pathways become overactive, leading to the hallmark recurrent fevers and serositis. Because it is autosomal recessive, both parents must typically carry a mutation for the child to manifest the disease, though some patients may present with atypical clinical features depending on their specific genotype.

What are the primary symptoms and diagnostic markers of FMF?

The clinical presentation of Familial Mediterranean Fever is characterized by short, episodic bouts of high fever accompanied by inflammation of the lining of the abdomen (peritonitis), the lungs (pleuritis), or the joints (arthritis). During these episodes, specific inflammatory markers are typically elevated, providing essential diagnostic clues for physicians:

• Serum Amyloid A (SAA): Elevated levels during and sometimes between attacks.


• C-Reactive Protein (CRP): A standard marker for systemic inflammation.


• Fibrinogen and Erythrocyte Sedimentation Rate (ESR): Often significantly increased during acute flares.


• Genetic Testing: Identification of pathogenic variants in the MEFV gene confirms the clinical diagnosis.

How does the DiseaseMaps community support those with FMF?

Navigating the diagnostic journey of Familial Mediterranean Fever can be isolating, especially given the rarity of the condition. Our community of 264 members serves as a vital resource for sharing coping strategies, managing the emotional burden of chronic pain, and discussing the impact of Familial Mediterranean Fever on daily life. By connecting with others who understand the unique challenges of autoinflammatory diseases, patients often find it easier to advocate for their needs during clinical visits and manage the long-term nature of their treatment plans.

Next steps

• Consult a rheumatologist or an immunologist who specializes in autoinflammatory diseases to confirm your diagnosis and treatment plan.


• Ensure your medical records correctly utilize the ICD-10 code E85.0 to facilitate insurance coverage for necessary medications.


• Join the DiseaseMaps.org community to connect with other patients and caregivers navigating life with Familial Mediterranean Fever.


• Keep a detailed journal of your flare-ups, including duration, temperature, and specific symptoms, to share with your medical team.
