Incontinentia Pigmenti is classified under ICD-10 code Q82.3 and ICD-9 code 757.33. These billing and diagnostic codes are used internationally to identify this rare, X-linked dominant genetic disorder characterized by multisystem involvement, including dermatological, dental, ocular, and neurological manifestations. What is the clinical significance of Incontinentia Pigmenti? Incontinentia Pigmenti is a rare genodermatosis typically caused by mutations in the IKBKG (NEMO) gene.

Incontinentia Pigmenti is a rare genodermatosis typically caused by mutations in the IKBKG (NEMO) gene. Because it is X-linked dominant, it is predominantly seen in females; it is usually lethal in males in utero, except in cases of Klinefelter syndrome (XXY) or somatic mosaicism. The 158 members of our Incontinentia Pigmenti community at DiseaseMaps.org frequently discuss the four distinct stages of skin lesions, which range from inflammatory vesicles to permanent hyperpigmentation.
While the ICD-10 code Q82.3 and ICD-9 code 757.33 are essential for medical documentation and insurance purposes, a definitive diagnosis of Incontinentia Pigmenti relies on clinical criteria and molecular genetic testing. Physicians look for the characteristic skin patterns alongside secondary findings such as hypodontia (missing teeth), retinal vascular abnormalities, and potential developmental delays.
Management of Incontinentia Pigmenti requires a multidisciplinary approach due to the systemic nature of the condition. Patients often require coordinated care across several specialties:
