Current polydactyly or syndactyly
Current polydactyly or syndactyly
What This Code Means
Receiving DQ code D221.90 means the DoDMERB physician reviewer determined that your medical history or exam findings related to current polydactyly or syndactyly 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 Musculoskeletal Conditions
Key Factors for Waiver Approval
- Documentation of full rehabilitation, strength, and agility
- No recurrent dislocations or chronic pain
- Full range of motion confirmed by orthopedic evaluation
- Active participation in competitive sports post-recovery
For scoliosis cases, the key threshold is the Cobb angle measurement. Having your own imaging and specialist evaluation ready — rather than relying solely on DoDMERB's assessment — can strengthen your case.
