ICD10 code of Carney Complex and ICD9 code

Carney Complex is classified under the ICD-10-CM code Q87.2 (Congenital malformation syndromes predominantly involving limbs), while it does not have a unique, dedicated ICD-9 code, often being grouped under 759.89 (Other specified congenital anomalies). Because Carney Complex is a rare, multisystem genetic disorder, these codes are used for administrative tracking rather than specific clinical diagnosis.

What is the clinical significance of Carney Complex?

Carney Complex is a rare, autosomal dominant multiple neoplasia syndrome characterized by spotty skin pigmentation (lentiginosis), endocrine overactivity, and specific tumors like cardiac myxomas. With 69 members currently sharing their experiences on DiseaseMaps.org, we recognize how challenging it is to manage a condition that affects the heart, skin, and endocrine glands simultaneously. Understanding the genetic basis of Carney Complex is essential for long-term surveillance.

Is Carney Complex hereditary?

Yes, Carney Complex is typically inherited in an autosomal dominant pattern, meaning an affected individual has a 50% chance of passing the pathogenic variant to their offspring. Approximately 70% of cases are caused by inactivating mutations in the PRKAR1A gene located on chromosome 17q24. Identifying this mutation is a cornerstone of diagnosing Carney Complex in families, and genetic counseling is strongly recommended for all first-degree relatives.

How is Carney Complex diagnosed?

Diagnosis of Carney Complex is primarily clinical, based on the Stratakis-Carney criteria. Patients must meet at least two of the following major criteria to receive a clinical diagnosis:

• Cardiac myxoma (often recurrent)


• Primary pigmented nodular adrenocortical disease (PPNAD)


• Large-cell calcifying Sertoli cell tumor (LCCSCT)


• Acromegaly due to growth hormone-secreting pituitary adenoma


• Psammomatous melanotic schwannoma


• Blue nevi or atypical lentiginosis

Next steps

• Consult with a clinical geneticist to discuss PRKAR1A testing for yourself and family members.


• Schedule regular cardiac screenings, including echocardiograms, as cardiac myxomas are a leading cause of mortality in Carney Complex.


• Join the DiseaseMaps.org community to connect with other patients and caregivers navigating the complexities of Carney Complex.


• Maintain a specialized medical team, including endocrinologists and cardiologists, to monitor for the endocrine and cardiac manifestations of Carney Complex.
