What the denial letter says
"Hereditary, congenital, and developmental conditions are excluded under Section [X.Y] of your policy."
What insurers really mean
The carrier is saying this condition is genetic and not their problem. Whether they're right depends on what your specific policy says: most current carriers cover hereditary conditions, sometimes by default, sometimes via rider. Older policies were stricter.
How to contest it
- 1
Read your policy's hereditary/congenital section. If it doesn't specifically exclude the named condition, the denial may be on shaky ground.
- 2
Confirm whether your policy has a hereditary-conditions rider, and whether it was active at the time of claim.
- 3
If you switched coverage levels mid-policy, check which level was active when symptoms first appeared — that may determine which exclusions apply.
- 4
Push for the carrier to identify the specific policy section that backs the denial — generic 'hereditary excluded' language is sometimes not in the actual contract.
