MEB, PEB and the IDES Process Explained

The Integrated Disability Evaluation System (IDES) is the joint DoD and VA process for deciding whether a medical condition makes you unfit to continue serving — and if so, what you are entitled to.

The point of "integrated" is that you are rated once. A single set of disability ratings drives both your DoD benefits and your VA benefits, rather than two separate evaluations reaching two different answers.

It runs in two stages:

The MEB — Medical Evaluation Board. Documents your medical status and duty limitations. The MEB does not decide your future; it assembles the record.

The PEB — Physical Evaluation Board. Uses that record to determine fitness to perform military duties and eligibility for benefits. This is where the decision is made.

The PEB reaches a fit/unfit determination, and there are four dispositions if you are found unfit:

  • Separated without benefit
  • Separated with severance pay
  • Permanent Disability Retirement List (PDRL)
  • Temporary Disability Retirement List (TDRL)

Found fit, you return to duty and continue serving.

Who is eligible?

You do not choose to enter IDES. You are referred when you meet the referral criteria — typically a condition that may prevent you performing your duties.

The threshold that decides the outcome is 30%. Permanent disability retirement is assigned where you are found unfit and either have more than 20 years of service or a rating of 30% or higher, with the condition unlikely to improve. Below 30% and under 20 years, the outcome is generally separation with severance pay rather than retirement.

That distinction is worth understanding early, because it changes everything downstream: retirement brings retired pay and TRICARE access, severance is a lump sum that the VA then recoups against compensation for the same condition.

VR&E is also accessible through IDES, and severely injured members can start it before a rating is issued.

How do I apply?

  • You do not apply — you are referred: What you control is how well the record is built.
  • Engage with the MEB properly: It assembles the evidence the PEB decides on. An incomplete MEB narrows your options later.
  • Understand where 30% sits for you: It is the line between medical retirement and severance, and the consequences differ substantially.
  • Get a PEB Liaison Officer or legal counsel involved: You are entitled to representation, and these decisions are appealable.
  • Ask about VR&E during the process: It is accessible through IDES, and severely injured members can start before a rating issues.
  • Know that severance is recouped: If you are separated with severance pay, the VA recoups it against compensation for that condition. Plan on that, not against it.

Common questions

What is the difference between the MEB and the PEB?

The MEB documents your medical status and duty limitations. The PEB uses that record to decide whether you are fit for duty and what benefits you are eligible for.

What does IDES mean by integrated?

You are rated once, and that single set of ratings drives both your DoD and your VA benefits — rather than two separate evaluations reaching different answers.

What outcomes can the PEB reach?

Fit, meaning you return to duty. Or unfit, with one of four dispositions: separated without benefit, separated with severance pay, permanent disability retirement, or temporary disability retirement.

Why does 30% matter?

Permanent disability retirement generally requires being found unfit with either 20+ years of service or a rating of 30% or higher. Below that, the outcome is usually severance pay instead.

Can you challenge a PEB finding?

Yes. You are entitled to representation and the findings are appealable — a PEB Liaison Officer or legal counsel is the route.
