Short answer · Medically reviewed summary · Last updated: 2026-05-08
The ICD-10 code for Ichthyosis is primarily categorized under Q80, while the ICD-9 code is 757.1. Because Ichthyosis represents a large, heterogeneous group of genetic skin disorders, specific sub-types often require additional decimal extensions to accurately reflect the clinical diagnosis. What is the clinical significance of Ichthyosis coding? Ichthyosis is not a single condition but a family of rare genetic skin disorders characterized by persistent, widespread scaling of the skin.

ICD-10 and ICD-9 codes for Ichthyosis, with classification details for clinicians, coders and patients.
The ICD-10 code for Ichthyosis is primarily categorized under Q80, while the ICD-9 code is 757.1. Because Ichthyosis represents a large, heterogeneous group of genetic skin disorders, specific sub-types often require additional decimal extensions to accurately reflect the clinical diagnosis.
What is the clinical significance of Ichthyosis coding?
Ichthyosis is not a single condition but a family of rare genetic skin disorders characterized by persistent, widespread scaling of the skin. Using the correct ICD-10 code (Q80) or ICD-9 code (757.1) is essential for clinical documentation, insurance reimbursement, and tracking epidemiological data. At DiseaseMaps.org, 36 people with Ichthyosis have shared their experiences, highlighting how these codes help patients navigate the complex healthcare landscape.
How is Ichthyosis classified in medical coding?
While the umbrella code for Ichthyosis is Q80, clinicians must often specify the form to ensure proper care coordination. Common classifications include:
- Q80.0: Ichthyosis vulgaris (the most common form).
- Q80.1: X-linked ichthyosis.
- Q80.2: Congenital ichthyosiform erythroderma (CIE).
- Q80.3: Congenital bullous ichthyosiform erythroderma.
- Q80.4: Harlequin fetus (a severe, rare form).
Is Ichthyosis hereditary?
Most forms of Ichthyosis are hereditary, caused by mutations in genes involved in skin barrier formation and keratinization. Genetic counseling is highly recommended for families living with Ichthyosis to understand the inheritance pattern, which can be autosomal dominant, autosomal recessive, or X-linked depending on the specific subtype.
How does the DiseaseMaps community support those with Ichthyosis?
Living with a condition that affects your largest organ can be isolating. The 36 members of the DiseaseMaps community with Ichthyosis share practical management strategies—such as specialized moisturizing routines and environmental adjustments—that go beyond the diagnostic codes found in medical charts.
