ICD10 code of Melorheostosis and ICD9 code

Melorheostosis is classified under the ICD-10 code Q78.8 (Other specified osteochondrodysplasias), while its legacy ICD-9 code is 756.59 (Other specified anomalies of bone and cartilage). These codes are used for medical billing and clinical tracking of this rare, non-hereditary sclerosing bone dysplasia.

What is the clinical classification of Melorheostosis?

Melorheostosis is a rare, non-hereditary condition often referred to as "dripping candle wax" bone disease due to its characteristic radiographic appearance. Because it is a rare skeletal disorder, it does not have a unique, disease-specific ICD code; instead, Melorheostosis is categorized under broader classifications for bone dysplasias to facilitate insurance processing and epidemiological research.

How is Melorheostosis diagnosed?

Diagnosis of Melorheostosis is primarily based on clinical symptoms and distinct radiographic imaging. Patients often present with localized pain, stiffness, or limb deformities. Our DiseaseMaps.org community, which currently includes 65 members living with Melorheostosis, often highlights the diagnostic journey as a pivotal moment in managing the condition's impact on mobility and daily life.

What are the key features of Melorheostosis?

While the exact etiology remains under investigation, clinical researchers recognize several hallmark features associated with Melorheostosis:

• Radiographic appearance: Cortical hyperostosis resembling flowing wax on an X-ray.


• Skeletal distribution: Typically affects long bones of the extremities, often in a sclerotomal distribution.


• Soft tissue involvement: Potential for muscle contractures, joint stiffness, and vascular malformations.


• Symptom onset: While the condition can present at any age, symptoms frequently manifest in childhood or early adulthood.

Next steps

• Consult an orthopedic oncologist or a rheumatologist specializing in rare bone dysplasias.


• Connect with the 65 members of the Melorheostosis community at DiseaseMaps.org to share experiences and coping strategies.


• Request a referral for a baseline DXA scan or specialized imaging to monitor bone density and progression.
