"History of congential disorders of cornification including but not limited to ichthyosis vulgaris, x-linked ichthyosis, lamellar ichthyosis, Darier's Disease, Epidermal Nevus Syndrome, and any palmo-plantar keratoderma"
What This Code Means
Receiving DQ code D112.21 means the DoDMERB physician reviewer determined that your medical history or exam findings related to history of congenital disorders of cornification do not currently meet Department of Defense accession standards as defined in DoDI 6130.03.
This does not end your candidacy. Many conditions flagged under this code are waiverable. The next step is understanding the exact standard that applies to your situation and whether a waiver request is appropriate for your commissioning source.

Waiver Outlook for Skin & Dermatology Conditions
Key Factors for Waiver Approval
- No requirement for ongoing prescription medication (especially steroids)
- Skin clear of active lesions for at least one year
- Condition limited to small areas with no systemic impact
- Dermatologist evaluation confirming resolved or stable condition
If childhood eczema was misinterpreted as a current condition, a dermatologist letter clarifying it resolved in early childhood can be the single document that secures your waiver.
