Secondary Condition Claim · VASRD 7914
Hyperthyroidism Secondary to Osteitis Fibrosa
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Hyperthyroidism when it develops after Osteitis Fibrosa.
Why Hyperthyroidism Is Linked to Osteitis Fibrosa
Common underlying cause of bone breakdown
Primary condition · VASRD 5029
Osteitis Fibrosa
Bone softening and resorption due to hormone imbalance, often with kidney issues.
Secondary condition · VASRD 7914
Hyperthyroidism
Overactive thyroid producing excess hormones, causing weight loss, fast heartbeat, and anxiety.
Hyperthyroidism VA Rating Tiers
The VA rates Hyperthyroidism the same way whether it's claimed directly or as secondary to Osteitis Fibrosa — severity of Hyperthyroidism itself determines the percentage.
Example combined rating
10% Osteitis Fibrosa + 30% Hyperthyroidism = 37%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 10% and 30% combine to 37%, not 40%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
Evidence for a Hyperthyroidism Secondary Claim
- •Thyroid function lab history
- •Medication records
- •Endocrinology consults
