ICD10 code of Camurati-Engelmann disease and ICD9 code

Camurati-Engelmann disease, also known as progressive diaphyseal dysplasia, is classified under the ICD-10 code Q78.3 (progressive diaphyseal dysplasia) and the ICD-9 code 756.59 (other specified disorders of osteogenesis). These codes are used by healthcare providers and insurance systems to identify this rare genetic bone disorder characterized by the thickening of the shafts of long bones.

What exactly is Camurati-Engelmann disease?

Camurati-Engelmann disease is a rare autosomal dominant skeletal disorder that primarily affects the long bones of the arms and legs. It is categorized as a type of craniotubular dysplasia. In individuals with Camurati-Engelmann disease, the outer layer of the bone (the cortex) becomes abnormally thickened, leading to symptoms such as bone pain, muscle weakness, and a characteristic "waddling" gait. Because it is a systemic condition, it requires a multidisciplinary approach to manage the orthopedic and systemic complications that often arise during childhood or adolescence.

How are the ICD-10 and ICD-9 codes used for this condition?

Medical coding is essential for ensuring that patients with Camurati-Engelmann disease receive appropriate care and that their medical records are accurately maintained. The ICD-10 code Q78.3 is the current international standard, while the ICD-9 code 756.59 is largely historical but may still appear in older medical charts. Using the correct code for Camurati-Engelmann disease is vital for:

• Facilitating insurance authorization for specialized treatments and monitoring.


• Tracking patient populations in global health registries.


• Assisting researchers in identifying cohorts for clinical trials.


• Ensuring continuity of care when transitioning between different healthcare systems.

Is Camurati-Engelmann disease hereditary?

Yes, Camurati-Engelmann disease is a genetic condition caused by mutations in the TGFB1 gene. It follows an autosomal dominant inheritance pattern, meaning that an affected individual has a 50% chance of passing the gene mutation to each of their children. While the clinical presentation of Camurati-Engelmann disease can vary significantly even within the same family—a phenomenon known as variable expressivity—genetic counseling is highly recommended for families navigating the implications of this diagnosis.

What does the community experience look like?

Living with a rare diagnosis like Camurati-Engelmann disease can feel isolating, but you are not alone. Currently, 107 people with Camurati-Engelmann disease have joined the DiseaseMaps.org community to share their experiences, symptoms, and coping strategies. Connecting with others who understand the unique pain and mobility challenges associated with Camurati-Engelmann disease can provide invaluable emotional support and practical insights into managing daily life with this condition.

Next steps

• Consult a geneticist to confirm a diagnosis of Camurati-Engelmann disease through targeted TGFB1 gene sequencing.


• Schedule regular follow-ups with a pediatric or adult orthopedist to monitor bone density and structural changes.


• Join the community at DiseaseMaps.org to connect with other patients and families navigating this rare condition.


• Work with a physical therapist to develop a low-impact exercise plan that supports mobility without overstressing affected bones.
