If my primary condition gets service-connected after being denied for a secondary claim, can I reopen the secondary claim?

When a secondary condition is denied because the underlying primary condition was not yet service-connected, that denial is not necessarily permanent. Once the primary condition (for example, migraines) is granted service connection, that grant can qualify as new and relevant evidence for the secondary conditions (such as depression or generalized anxiety) that were denied solely because the primary condition wasn't connected yet. Under 38 CFR 3.310, a secondary condition can be service-connected if it is caused or aggravated by an already service-connected disability. The correct vehicle to raise this again is a supplemental claim, filed on VA Form 20-0995, along with a statement pointing out that the primary condition has since been granted and that the denial letter itself acknowledged a current diagnosis of the secondary condition. Because the diagnosis element was already conceded in the prior decision (the "favorable findings" language), the remaining task is establishing the nexus between the now-service-connected primary condition and the secondary condition. A supporting medical opinion — either from a treating provider or obtained through a private nexus letter — that addresses the relationship can meaningfully strengthen the claim and increase the likelihood that VA schedules a Compensation & Pension exam to evaluate it, since a new grant of service connection combined with existing diagnostic evidence often meets the "new and relevant" threshold required for a supplemental claim to move forward. The same reasoning applies to conditions like plantar fasciitis or degenerative arthritis that may be secondary to the already service-connected ankle conditions; those would also be raised through a supplemental claim with medical evidence linking the new diagnoses to the ankles, rather than starting an entirely new original claim.

Outcomes on supplemental claims vary significantly depending on the quality and specificity of the nexus evidence submitted, and there is no guarantee that a favorable primary grant automatically results in approval of the secondary conditions — the medical linkage still has to be affirmatively shown. For context, in the appealed VA decisions in VetAid's library, service-connection appeals see vacated-or-remanded outcomes in about half of cases with a recorded disposition, straight denials affirmed in about 30%, and outright reversals or grants in about 7%; these are appellate-stage results for cases that were already appealed, not odds for an initial or supplemental claim, and appealed cases are not a representative sample of all claims, so they should be read as general context only, not a prediction for this case.

The concrete next step is to file VA Form 20-0995 for each previously denied secondary condition, attaching the recent decision granting the primary condition and, if possible, a treating provider's statement or nexus opinion linking the secondary condition to it.
