Diabetes claims live or die on the records because the rating schedule is written in recordable facts: treatment method, restrictions, episode counts, complication diagnoses. This guide lists what belongs in the file, in the order most veterans need it.
The diagnosis and the lab work
A current diagnosis from a provider, with the A1C values and glucose records behind it, establishes the first element. Laboratory history matters more here than in almost any other claim, because it documents the trajectory - when control slipped, how the disease moved from diet to medication to insulin, and how it tracked with everything else in your life.
The treatment and restriction records
The rating is built from how the diabetes is managed, so the file has to show the full regimen: prescriptions and doses, diet restrictions the provider actually recommended, and activity limits. A file that lists insulin but never records the dietary and activity restrictions gives the rater half the criteria.
Our rating guide shows exactly which criteria map to which percentage, and our C&P exam guide covers what the exam records.
Episode documentation
Emergency room records, hospital admissions, and urgent care visits for ketoacidosis or hypoglycemic reactions are the evidence for the upper percentages. If episodes were treated at home, your own statement counting them, with dates and descriptions, is the available record - imperfect, but better than silence.
Where veterans start
Every case is different, and there is no obligation at any step. When veterans want to understand what their records actually support, these are the two most common starting points:
- Medical records review
A licensed physician reviews your records for a $250 flat fee and identifies which conditions the available evidence may support. The fee is refunded in full if nothing supportable is identified.
- Nexus letter
When the records support one, a licensed provider writes the medical opinion that addresses the link between your condition and your service or an already service-connected disability.
Service records for the path you are on
For a presumptive claim, the service element is a DD-214 and duty records showing qualifying locations and periods - the Agent Orange list guide covers the rule. For a direct claim, service treatment records, personnel records, and buddy statements carry the in-service element. For a secondary claim, the primary condition's rating decision and the timeline records are the backbone, and our diabetes secondary to PTSD guide explains what the link requires.
The medical opinion
Presumptive claims rarely need one. Direct and secondary claims usually do: when the VA concedes the diagnosis but denies the link to service or to the primary condition, a reasoned medical opinion that reviews the records, explains the mechanism, and addresses the competing causes is the evidence that answers it. Our nexus letter guide explains what that contains, and our guide on why VA claims get denied helps identify which element the VA actually found missing.
Before you file
A medical records review looks at what you actually have and identifies which elements the file supports and which are missing - before the VA makes the same finding the hard way. Free accredited help with filing is available to every veteran through a Veterans Service Officer.
