Short answer · Medically reviewed summary · Last updated: 2026-04-07
Dyskeratosis congenita is classified under ICD-10 code Q82.8 (Other specified congenital malformations of skin) and historically under ICD-9 code 757.39 (Other specified congenital anomalies of skin). These codes are used for administrative and billing purposes, though the clinical management of Dyskeratosis congenita requires a multidisciplinary approach due to its multisystem nature. What is the clinical significance of Dyskeratosis congenita? Dyskeratosis congenita is a rare, multisystem genetic disorder characterized by defects in telomere maintenance.
ICD10 code of Dyskeratosis congenita and ICD9 code
ICD-10 and ICD-9 codes for Dyskeratosis congenita, with classification details for clinicians, coders and patients.
Dyskeratosis congenita is classified under ICD-10 code Q82.8 (Other specified congenital malformations of skin) and historically under ICD-9 code 757.39 (Other specified congenital anomalies of skin). These codes are used for administrative and billing purposes, though the clinical management of Dyskeratosis congenita requires a multidisciplinary approach due to its multisystem nature.
What is the clinical significance of Dyskeratosis congenita?
Dyskeratosis congenita is a rare, multisystem genetic disorder characterized by defects in telomere maintenance. The classic clinical triad of Dyskeratosis congenita includes abnormal skin pigmentation (reticular hyperpigmentation), nail dystrophy, and oral leukoplakia. However, the condition is most significantly defined by its impact on bone marrow function and the potential for premature aging symptoms, including pulmonary fibrosis and an increased susceptibility to malignancy. Because Dyskeratosis congenita affects multiple organ systems, patients often require lifelong surveillance by hematologists, dermatologists, and pulmonologists.
How is Dyskeratosis congenita diagnosed and classified?
Diagnosis of Dyskeratosis congenita is confirmed through a combination of clinical evaluation and genetic testing. Clinicians look for mutations in genes involved in the telomerase complex, such as DKC1, TERC, and TERT. Because the condition can present with varying degrees of severity—ranging from classic Hoyeraal-Hreidarsson syndrome to milder adult-onset forms—genetic counseling is essential. At DiseaseMaps.org, we have seen 33 people with Dyskeratosis congenita join our community, highlighting the importance of shared experiences in navigating this complex diagnostic journey.
What are the primary health risks associated with Dyskeratosis congenita?
The management of Dyskeratosis congenita focuses on monitoring for life-threatening complications that arise from telomere shortening. The following areas are of critical concern for individuals diagnosed with this condition:
- Bone Marrow Failure: The leading cause of mortality, requiring regular complete blood counts (CBC).
- Pulmonary Disease: Risk of pulmonary fibrosis, necessitating periodic pulmonary function tests.
- Malignancy: Significantly increased risk of squamous cell carcinoma (especially in the head, neck, and anogenital regions) and acute myeloid leukemia.
- Gastrointestinal Issues: Potential for esophageal strictures and liver disease.
- Dental Health: Increased prevalence of periodontal disease and caries, requiring specialized dental care.
Is Dyskeratosis congenita hereditary?
Yes, Dyskeratosis congenita is a genetic disorder that can be inherited in several ways depending on the specific gene mutation involved. It can follow an X-linked recessive, autosomal dominant, or autosomal recessive inheritance pattern. Because of these complex inheritance modes, we strongly recommend that families seek consultation with a clinical geneticist. Understanding the specific genetic mutation helps in predicting the clinical course and assessing the risks for other family members.
