PDRL vs TDRL: Permanent vs Temporary Disability Retired List Explained

When the Physical Evaluation Board finds a service member unfit for duty with a disability rating of 30% or higher (or 20 years of service), the member is retired, not separated. That retirement falls into one of two categories: the Permanent Disability Retired List (PDRL) or the Temporary Disability Retired List (TDRL).

Understanding the difference matters because TDRL is temporary by definition, and what happens at re-evaluation determines your long-term financial outcome.

The Permanent Disability Retired List (PDRL)

PDRL is exactly what it sounds like: a permanent disability retirement. To be placed on the PDRL, the PEB must determine that:

1. Your condition makes you unfit for duty
2. Your rating is 30% or higher (or you have 20+ years of service)
3. Your condition is stable, meaning it is unlikely to significantly improve or worsen

PDRL placement means your disability retirement pay is fixed and ongoing. You receive:

• Monthly disability retirement pay based on the higher of: (a) your disability percentage × your base pay, or (b) 2.5% × years of service × base pay (for members with 20+ years)
• Access to TRICARE and retiree benefits
• If rated 50% or higher, concurrent receipt of full VA disability compensation (CRDP rules apply) — you can combine your VA ratings to see whether you clear the 50% line

You will not be re-evaluated on PDRL. Your status is permanent.

The Temporary Disability Retired List (TDRL)

TDRL applies when the PEB finds you unfit and ratable at 30%+ but believes your condition may change, specifically, that it might improve. TDRL is appropriate for conditions that are acute, recently treated, or expected to stabilize over time.

On TDRL, you receive disability retirement pay calculated at the higher of: (a) your disability percentage × base pay (minimum 50% during TDRL per statute), or (b) 2.5% × years of service × base pay.

The minimum 50% rule is significant: even if your actual disability rating is 30%, you receive TDRL pay calculated at 50% of your base pay while on TDRL.

TDRL Re-Evaluations

While on TDRL, you are re-examined by a military physician (at a MTF or through contract) at least every 18 months, for up to 3 years (for placements on or after 1 January 2017; a 5-year cap applied to placements before that date). The purpose: has your condition improved, worsened, or stabilized?

At each re-evaluation, the reviewing PEB can:

Find the condition has stabilized → move you to PDRL at the current rating.

Find the condition has improved → reduce the rating. If the rating drops below 30% and you don't have 20 years, you may be separated with disability severance pay rather than retired. This is the scenario TDRL members fear.

Find the condition has worsened → increase the rating. If your condition has deteriorated, your rating may increase on PDRL.

Extend TDRL for another period up to the maximum (3 years for placements on or after 1 January 2017; 5 years before that date).

At the end of the TDRL period (3 years for placements on or after 1 January 2017; 5 years before that date), the service must make a final determination, either permanent retirement (PDRL) or separation.

How to Protect Your Outcome During TDRL

Get continuing medical care. Stay engaged with VA care and/or civilian providers. Your condition should be documented consistently, not just at re-evaluation time.

Attend all re-evaluations. Missing a TDRL re-evaluation can result in removal from TDRL without proper disposition.

Submit comprehensive evidence at re-evaluation. Your ongoing medical records, statements from treating providers, and your own statement about your functional limitations all contribute to the rating decision.

Work with a VSO or attorney. The stakes at TDRL re-evaluation are high, moving from TDRL to separation can mean losing monthly retirement pay. Free representation from organizations like the DAV or with a private attorney experienced in military disability law is worth pursuing.
