MEB, PEB, and IDES (active duty medical separation)

If you’re on active duty and your medical condition may render you unfit for duty, you’ll go through the Medical Evaluation Board / Physical Evaluation Board process. The Integrated Disability Evaluation System (IDES) is the modern joint DoD/VA version of this. Understanding how it interacts with VA disability is critical.

What MEB/PEB/IDES does

MEB decides whether you meet medical retention standards.
If MEB finds you don’t, PEB decides whether your condition is service-connected, the level of disability, and whether you’re fit for continued service.
IDES is the unified process — your MEB/PEB and your VA disability rating are conducted in parallel during your final months in service, with one consolidated exam (“Medical Examination Process” or MEP) feeding both systems.

Key distinction: DoD rating vs. VA rating

DoD rates ONLY the conditions that made you unfit for duty. Often just 1–3 conditions.
VA rates EVERY service-connected condition — fit-for-duty or not.
Both ratings are issued at the end of IDES.
DoD rating determines whether you’re medically retired (>=30% combined) or separated with severance pay (<30% combined).
VA rating determines your monthly disability compensation going forward.

Why your VA rating often exceeds your DoD rating

Because VA rates everything. You might be DoD-rated 30% (medical retirement) for the one knee that made you unfit, but VA-rated 80% combined when they add in your tinnitus, back, sleep apnea, anxiety, and the other knee.

How to maximize VA outcomes in IDES

List every claimable condition on your IDES VA claim, not just the unfit-for-duty ones. The MEB only cares about fitness; the VA cares about everything.
Use the Symptom Wizard before you complete the VA portion of IDES — surface everything.
Get presumption-eligible conditions claimed even if asymptomatic. PACT Act-eligible? File for any qualifying condition even mild ones.
Mental health on IDES is a sensitive call. Mental health conditions can be unfit-for-duty triggers. If filing mental health is going to accelerate your separation, that’s something to consider. Talk to a Vet Center counselor off-the-record before you initiate.

Severance pay vs. medical retirement

<30% combined DoD rating = separation with severance pay (lump sum, taxable).
>=30% combined DoD rating, less than 20 years service = medical retirement (monthly retirement pay).
20+ years service = retirement either way; medical retirement may improve certain calculations.

The VA waiver / offset issue

Military retirement pay is offset by VA disability compensation by default. See CRDP and CRSC.

CRDP restores the offset for 20-year retirees rated 50%+.
CRSC can apply to combat-related disabilities regardless of service length, including Chapter 61 medical retirees.

Severance pay recoupment

If you receive severance pay AND later get VA disability for the same condition, VA recoups the severance pay from your VA disability over time. This isn’t a reason to refuse severance — VA is just ensuring you’re not double-compensated for the same condition.

VA appeals from IDES rating

If the IDES VA rating is wrong, you have the same AMA appeal rights as any veteran. The IDES VA rating becomes your initial VA decision; the 1-year appeal clock starts from that decision.

Practical timeline

MEB initiation → MEB decision: 30–90 days
PEB review → PEB decision: 60–120 days
IDES VA rating issued in parallel
Separation: typically 4–8 months from MEB initiation, sometimes longer
