Secondary Condition Claim · VASRD 5013
Osteoporosis Secondary to Hyperthyroidism
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 Osteoporosis when it develops after Hyperthyroidism.
Why Osteoporosis Is Linked to Hyperthyroidism
Due to hormone imbalance
Primary condition · VASRD 7900
Hyperthyroidism
Hyperthyroidism is an overactive thyroid producing excess hormone, which speeds up metabolism and can cause rapid heartbeat, tremor, anxiety, heat intolerance and weight loss. Graves' disease is the most common cause and is rated under the same code.
Secondary condition · VASRD 5013
Osteoporosis
Osteoporosis is loss of bone mineral density that leaves bone fragile enough to fracture from minor stress. The schedule titles DC 5013 "Osteoporosis, residuals of" — it rates what the disease has left behind, not the bone-density number, and it does that on limitation of motion of the affected parts.
Osteoporosis VA Rating Tiers
The VA rates Osteoporosis the same way whether it's claimed directly or as secondary to Hyperthyroidism — severity of Osteoporosis itself determines the percentage.
| Rating | Criteria |
|---|---|
| 10% | Per joint, when motion is limited but not enough to rate on its own |
| 0% | Service-connected, but no compensable limitation of the affected parts |
Example combined rating
30% Hyperthyroidism + 10% Osteoporosis = 37%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 30% and 10% combine to 37%, not 40%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.

Evidence for a Osteoporosis Secondary Claim
- •Range-of-motion measurements, in degrees, for every part osteoporosis has damaged — this is the only thing DC 5013 rates, and it is the measurement most osteoporosis claims are missing.
- •Imaging and operative reports for each fragility fracture, identifying the exact vertebra or bone, since the fracture is usually rated under that body part's own diagnostic code rather than under DC 5013.
- •A DEXA scan with the T-score and the treating clinician's diagnosis, which establish the disease even though no percentage turns on the number.
- •Records of the in-service cause where one applies — long-term corticosteroid therapy, prolonged immobilization, hypogonadism, or an endocrine condition already service-connected.
- •Examination findings documenting objective painful motion, spinal deformity or loss of height, which support both the per-joint 10 percent and the 38 CFR 4.59 minimum.
Common questions about Osteoporosis secondary to Hyperthyroidism
- Can Osteoporosis be service-connected as secondary to Hyperthyroidism?
- Yes. Under 38 CFR § 3.310, a condition that is caused or aggravated by an already service-connected disability can be granted secondary service connection. Due to hormone imbalance You'll need a current Osteoporosis diagnosis and a medical nexus opinion linking it to your service-connected Hyperthyroidism — the same s…
- What VA rating can I get for Osteoporosis as a secondary condition?
- Osteoporosis is rated under VASRD diagnostic code 5013 using the same criteria whether it's a direct or secondary claim: possible ratings are 10%, 0%. The rating depends on the severity of Osteoporosis itself, not on the severity of Hyperthyroidism.
- How does a secondary Osteoporosis claim affect my combined VA rating?
- The VA doesn't add ratings together. Using the official combined-ratings formula (38 CFR 4.25): a 30% rating for Hyperthyroidism combined with a 10% rating for Osteoporosis (example figures) produces a combined rating of 37%, not 40%. Approving Osteoporosis as secondary still typically raises your overall combined rat…
- What evidence do I need to service-connect Osteoporosis as secondary to Hyperthyroidism?
- Strong evidence for the underlying Osteoporosis diagnosis includes: Range-of-motion measurements, in degrees, for every part osteoporosis has damaged — this is the only thing DC 5013 rates, and it is the measurement most osteoporosis claims are missing.; Imaging and operative reports for each fragility fracture, ident…
