If the VA denied your claim for Dependency and Indemnity Compensation (DIC) — the monthly benefit paid to eligible survivors when a service-connected condition caused or contributed to a veteran's death — the denial letter probably said something like "the evidence does not show" that the service-connected condition caused the death. That language points to a specific gap: the file never contained a reasoned medical opinion connecting the condition to the death. A denial on those grounds is not a ruling that the connection is false — it is a finding that no qualified physician explained it in the record.
Start with the DIC services page — what a cause-of-death opinion is, and when one fits a case.
What "insufficient medical evidence" usually means
Many surviving spouses first learn that cause-of-death medical opinions exist only after a denial. The denial itself usually traces to one of a few evidence problems: the death certificate lists an immediate cause that is not service-connected; the terminal hospital records never discuss the service-connected condition's role; or a VA reviewer's opinion said "less likely than not" without weighing the full history. In each case, the rater had no medical analysis in front of them that answered the causation question in VA's terms.
Principal cause, contributory cause — the distinction that decides these claims
Under 38 CFR § 3.312, a service-connected condition does not have to be the principal cause of death — the immediate or underlying cause. It can instead be a contributory cause: one that "contributed substantially or materially" to death, combined to cause it, or aided its production. For example, where a veteran was service-connected for diabetes and the records document its progression into cardiovascular disease before a fatal cardiac event, a physician may be able to explain a contributory pathway even though the death certificate says only "cardiac arrest." Whether that opinion is supportable depends entirely on what the records actually show — not on the diagnosis alone.
How a cause-of-death opinion answers a denial
VA's decision-review system allows a Supplemental Claim (VA Form 20-0995) when you have new and relevant evidence — information VA has not considered that bears on the claim. A physician-authored cause-of-death opinion is built to be exactly that: a review of the complete record that identifies the medical pathway, engages any unfavorable VA opinion point by point, and states a conclusion in the standard VA uses — whether it is at least as likely as not that the service-connected condition caused or contributed substantially or materially to the death. The physician's role is the medical analysis; eligibility and the final decision remain VA's, as described on VA's DIC page.
A medical opinion may help when...
- The denial says the evidence does not link the service-connected condition to the death, and no independent physician opinion was ever in the file.
- The death certificate names only an immediate cause, and the service-connected condition's documented progression suggests a contributory role.
- A VA reviewer's opinion was brief or did not address the full treatment history.
- The terminal records are dense, and no one has traced the medical chain in plain, reviewable reasoning.
These are educational prompts, not eligibility determinations. The records and a case-specific medical rationale determine whether an opinion is supportable — which is why review comes before any commitment.
Records worth gathering before anyone writes an opinion
- The VA denial letter, including the reasons-and-bases section.
- The death certificate (the long form, with all listed causes).
- Terminal hospitalization or hospice records.
- VA rating decisions showing the service-connected conditions.
- Treatment records for the service-connected condition in the years before death, plus any autopsy report.

Who writes these opinions here
At Hart Causation and Claims, every opinion is personally authored by Dr. John H. Hart, Jr., M.D., an ABIM board-certified internist with more than 25 years in practice and a retired Senior Flight Surgeon in the USAF Reserve. Cause-of-death analysis — cardiovascular disease, diabetes, renal failure, the ways chronic conditions interact at the end of life — is internal medicine's home ground.
