MEB and PEB: Medical Separation and the Disability Evaluation System

How the military decides whether a medical condition ends your service, what rating and benefits come with that, and how it hands you off to the VA.

Current as of: June 2026 · Reading time: about 9 minutes · For: service members being medically separated or retired

If a medical condition may keep you from continuing to serve, the military runs you through the Disability Evaluation System. Two boards decide your case. A Medical Evaluation Board (MEB) asks whether your condition meets the standards to stay in. A Physical Evaluation Board (PEB) then finds you Fit or Unfit, and if Unfit, assigns a military disability rating and a disposition. This page explains how the MEB and PEB work, the single exam that feeds both the military and the VA, the dispositions you can receive, how to challenge a finding, and how the process connects to the VA claim the rest of this site covers.

The one thing to understand first

The military and the VA rate you differently, and that gap is normal. The military rates only the conditions that make you unfit to serve. The VA rates every condition connected to your service. So you can leave with a low military rating and a high VA rating from the same exam (DoD, 2023; VA, 2026).

The Disability Evaluation System

The Disability Evaluation System (DES) is how the military decides whether an illness or injury keeps you from doing your job, and what disability benefits you receive if it does. Most service members today go through the Integrated Disability Evaluation System (IDES), a joint DoD and VA process that combines the military fitness decision and the VA disability rating into one timeline using one set of exams (DoD, 2023; VA, 2026).

You enter the system by referral, usually when a physician determines that within about 12 months you are not likely to return to full duty (DoD, 2023). Once referred, you are assigned two people to help you through it:

  • A Physical Evaluation Board Liaison Officer (PEBLO) from your branch, who tracks your case and explains each step.
  • A VA Military Services Coordinator (MSC), who helps you file your VA claim and lists the conditions to be examined (DoD, 2023).

IDES has four phases in plain terms. A medical phase (the MEB), a single set of VA exams, a board decision (the PEB) with proposed ratings, and a transition out of service with your VA benefits ready to start. The older, non-integrated process (the legacy DES) ran the military and VA pieces separately, which took longer.

The Medical Evaluation Board (MEB)

The MEB is the medical fact-finding phase. A board of physicians reviews your records and the exam results and asks one question. Does each referred condition meet the medical retention standards for staying in the service (DoD, 2023)?

The MEB does not assign a disability rating and does not decide whether you stay or go. It documents your conditions and sorts them into those that meet retention standards and those that may not, then forwards the case to the PEB. You receive the MEB findings and have a chance to review them and add a statement before they move on.

The single IDES exam In IDES, the VA performs the Compensation and Pension (C&P) exams once, and those same exams feed both the military board and the VA rating. List every condition you want considered with your MSC before the exams happen, because the VA rates what was claimed and examined (DoD, 2023; VA, 2026).

The Physical Evaluation Board (PEB)

The PEB makes the decision the MEB does not. It determines whether you are Fit or Unfit for continued service. A condition is unfitting when it prevents you from performing the duties of your office, grade, rank, or rating. For each unfitting condition, the PEB applies the VA Schedule for Rating Disabilities (the VASRD, found in 38 C.F.R. Part 4) to assign a military disability rating, and then sets a disposition (DoD, 2023).

Informal PEB and formal PEB

  • Informal PEB (IPEB): a records-only review. You are not present. The IPEB issues proposed findings, a Fit or Unfit determination, the unfitting conditions, the rating, and the disposition.
  • Formal PEB (FPEB): an in-person hearing you can request if you disagree with the informal findings. You may appear, present evidence, and have counsel, including a free military attorney detailed to represent you (DoD, 2023).

If the PEB finds you Fit, you return to duty. If it finds you Unfit, the disposition depends mainly on your rating and your years of service, covered next.

The four dispositions

An Unfit finding leads to one of these outcomes. The 30 percent line and your years of service drive which one applies (10 U.S.C. Chapter 61; DoD, 2023).

PEB dispositions. The combined military rating counts only unfitting conditions. Twenty or more years of service can change the result.
Disposition When it applies
Return to dutyThe PEB finds you Fit. You stay in service.
Separation with severance payFound Unfit, combined military rating below 30%, and fewer than 20 years of service. You receive a one-time disability severance payment, not monthly retired pay.
Permanent disability retirement (PDRL)Found Unfit, rating 30% or higher (or 20+ years of service), and the condition is stable. You go on the Permanent Disability Retired List with monthly retired pay and military retiree benefits.
Temporary Disability Retired List (TDRL)Found Unfit, rating 30% or higher, but the condition is not yet stable. You receive temporary retired pay and are re-examined periodically.

TDRL, the temporary list

The TDRL holds cases where the rating is 30 percent or more but the condition could still change. You are re-examined on a set schedule. For members placed on the TDRL on or after January 1, 2017, the maximum time on the list is three years (10 U.S.C. Chapter 61; DoD, 2023). At the end, the PEB either moves you to permanent retirement, separates you with severance if your rating has dropped below 30 percent, or finds you fit.

Bottom line Thirty percent is the line between a one-time severance check and monthly medical retirement. Severance comes with a low military rating and short service. Medical retirement (PDRL or TDRL) comes with 30% or more, or with 20 or more years of service.

Why your military rating and VA rating differ

This catches almost everyone, so it is worth stating plainly. Both numbers use the same VASRD, but they rate different sets of conditions (DoD, 2023; VA, 2026).

  • The military rating counts only the conditions the PEB found unfitting. If one back condition makes you unable to do your job, the military may rate that one condition.
  • The VA rating counts all of your service-connected conditions, fitting or not, including tinnitus, sleep apnea, knees, mental health, and anything else connected to service.

So a member separated with a 10 or 20 percent military rating can still receive a much higher combined VA rating from the very same exams. The military number sets your military separation or retirement benefit. The VA number sets your monthly VA disability compensation. They are not supposed to match.

Severance pay and the VA offset

Disability severance pay is a one-time payment based on your basic pay and years of service. By law it equals 2 months of basic pay for each year of service, with statutory minimums and a cap (10 U.S.C. Chapter 61; CRS, IF12042).

The recoupment rule

If you later receive VA disability compensation for the same condition the severance was paid for, the VA generally withholds your monthly compensation until the severance amount is recovered (38 C.F.R. 3.700; VA, 2026). This is the recoupment offset. It applies to the same disability only, so VA compensation for other conditions is not withheld.

The combat-related exception For members separated under Chapter 61 on or after January 28, 2008, the VA does not recoup severance paid for a disability incurred in a combat zone or in combat-related operations as designated by DoD (38 C.F.R. 3.700; VA, 2026). Members eligible to retire at separation, or eligible for Combat-Related Special Compensation, may also avoid recoupment.

Medical retirement works differently. Retired pay and VA compensation can interact through waiver and offset rules, and programs like Combat-Related Special Compensation can restore some of what is offset. See the CRSC section in the pension guide below.

If you disagree: appeals and review

You have several ways to challenge a finding, in order (DoD, 2023; service review board rules).

While still in the process

  • Rebuttal: you can submit a written rebuttal to the MEB or the informal PEB findings, with new evidence or argument.
  • Formal PEB hearing: if you disagree with the informal PEB, you can request a formal hearing, appear in person, and be represented by a detailed military attorney at no cost.
  • VA reconsideration: because IDES uses VA exams, you can ask the VA to reconsider the proposed disability rating during the process.

After the process is final

  • Physical Disability Board of Review (PDBR): reviews disability cases for members separated with a combined rating of 20 percent or less between September 11, 2001 and December 31, 2009. It can change a past separation to a medical retirement (PDBR program rules).
  • Board for Correction of Military Records (BCMR or BCNR): the catch-all for correcting a military record outside the PDBR window, filed on DD Form 149 (10 U.S.C. 1552).

An accredited representative or a military law attorney can help with a formal PEB or a records-correction filing. See how to find help.

How this connects to your VA claim

The MEB and PEB decide your military future. Your VA disability claim is a separate track that starts at the same time and lasts the rest of your life. Because IDES files the VA claim for you using the single exam, much of the rest of this site picks up where the boards leave off (VA, 2026).

Bottom line Treat the PEB number and the VA number as two separate things. The PEB number affects your military separation or retirement. The VA number is your long-term disability compensation, and it usually rates more conditions.

Frequently asked questions

What is the difference between the MEB and the PEB?
The MEB is the medical phase. A board of physicians documents your conditions and asks whether each one meets the standards to stay in service. It does not assign a rating or decide your future. The PEB is the decision phase. It finds you Fit or Unfit, assigns a military disability rating to any unfitting condition using the VASRD, and sets your disposition.
Why is my military rating lower than my VA rating?
They rate different things. The military rates only the conditions that make you unfit to serve. The VA rates all of your service-connected conditions. A low military rating and a high VA rating from the same set of exams is normal, not a mistake.
What does the 30 percent rule mean?
A combined military disability rating of 30 percent or higher (or having 20 or more years of service) generally leads to medical retirement, the PDRL or TDRL, with monthly retired pay. A rating below 30 percent with fewer than 20 years of service generally leads to separation with a one-time severance payment instead.
Will the VA take back my severance pay?
The VA generally withholds monthly compensation until your severance is recovered, but only for the same condition the severance was paid for. Severance for a disability incurred in a combat zone or combat-related operations on or after January 28, 2008 is not recouped, and some other exceptions apply.
Can I challenge a PEB finding?
Yes. You can rebut the informal findings, request a formal PEB hearing where you appear in person with a free detailed military attorney, and after the case is final you can apply to the Physical Disability Board of Review (for certain 2001 to 2009 separations) or the Board for Correction of Military Records.
What is TDRL?
The Temporary Disability Retired List holds members rated 30 percent or higher whose condition is not yet stable. You receive temporary retired pay and are re-examined on a schedule. For placements on or after January 1, 2017, the maximum time on the list is three years, after which you are permanently retired, separated, or found fit.
