Secondary Condition Claim · VASRD 5020
Osteomyelitis Secondary to Hydronephrosis
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 Osteomyelitis when it develops after Hydronephrosis.
Primary condition · VASRD 7509
Hydronephrosis
Swelling of the kidney due to urine backup from obstruction.
Secondary condition · VASRD 5020
Osteomyelitis
A serious bone infection that can damage tissue and lead to disability.
Osteomyelitis VA Rating Tiers
The VA rates Osteomyelitis the same way whether it's claimed directly or as secondary to Hydronephrosis — severity of Osteomyelitis itself determines the percentage.
Example combined rating
30% Hydronephrosis + 30% Osteomyelitis = 51%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 30% and 30% combine to 51%, not 60%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
Evidence for a Osteomyelitis Secondary Claim
- •MRI or bone scan confirming infection
- •Hospital records showing treatment or surgery
- •Bone biopsy or positive culture
Common questions about Osteomyelitis secondary to Hydronephrosis
- Can Osteomyelitis be service-connected as secondary to Hydronephrosis?
- 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. You'll need a current Osteomyelitis diagnosis and a medical nexus opinion linking it to your service-connected Hydronephrosis — the same standard the VA uses for a…
- What VA rating can I get for Osteomyelitis as a secondary condition?
- Osteomyelitis is rated under VASRD diagnostic code 5020 using the same criteria whether it's a direct or secondary claim: possible ratings are 100%, 60%, 30%, 10%. The rating depends on the severity of Osteomyelitis itself, not on the severity of Hydronephrosis.
- How does a secondary Osteomyelitis 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 Hydronephrosis combined with a 30% rating for Osteomyelitis (example figures) produces a combined rating of 51%, not 60%. Approving Osteomyelitis as secondary still typically raises your overall combined ra…
- What evidence do I need to service-connect Osteomyelitis as secondary to Hydronephrosis?
- Strong evidence for the underlying Osteomyelitis diagnosis includes: MRI or bone scan confirming infection; Hospital records showing treatment or surgery; Bone biopsy or positive culture. For the secondary link itself, a nexus letter from a treating provider explaining how Hydronephrosis caused or aggravated Osteomyel…
