INSIDE THE PHARMACY GAP: WHEN VA AND TRICARE RULES COLLIDE FOR VETERAN FAMILIES
COMMENT
SHARE
Mixed VA/TRICARE households are discovering that pharmacy formularies (lists of covered drugs), refill windows, and mail-order rules don’t align, leading to confusion, coverage delays, and medication gaps.
This mistaken assumption sets the stage for real-world problems. While Veterans expect a single, comprehensive benefit, the friction arises because two separate programs operate under different sets of rules, a gap families rarely recognize until they experience it firsthand.
How One Household Revealed the Gap
Micah Campbell, an Army Veteran, is receiving VA care, while his spouse and children rely on TRICARE. Micah gets medications via VA mail-order. His wife uses TRICARE Home Delivery and the MTF pharmacy. Their teenager has a civilian prescription for ADHD medication. It may sound like there is a lot going on here - and there is, but this is far more common than people realize.
From the family’s perspective, it’s all one ecosystem. From the system’s perspective, it’s four separate pharmacy benefit designs that don’t talk to each other.

Mixed Coverage Is Normal, Not a Rare Scenario
Many Veterans enrolled in VA health care also maintain other coverage, including TRICARE, Medicare, Medicaid, or employer insurance. TRICARE covers spouses and children; VA does not. CHAMPVA covers certain spouses and children when TRICARE does not. Medicaid and employer plans often cover children with special health needs.
This mixed-coverage pattern is structural, but not unusual, and it’s why pharmacy friction shows up at the household level rather than inside a single benefit.
VA Pharmacy vs. TRICARE Pharmacy: Separate Systems With Separate Rules
The VA pharmacy is part of VA medical care. The VA Pharmacy Benefits Management (PBM) office maintains a single national formulary and primarily dispenses medications for enrolled Veterans based on VA medical treatment. Copays and exemptions depend on priority group, service connection, and medication tier.
TRICARE pharmacy is an insurance pharmacy benefit administered under the Defense Health Agency (DHA) through Express Scripts. According to the Defense Health Agency, TRICARE’s Uniform Formulary governs coverage tiers, and prescriptions may be filled at MTF pharmacies, TRICARE Home Delivery, retail network pharmacies, or non-network pharmacies, each with different quantity limits and copays.
Both are federally funded, but were never unified as a family pharmacy benefit. That’s the gap.
Where the Rules Collide for Veteran Families
Four fault lines consistently appear in mixed VA/TRICARE households:
Formulary Misalignment
A medication that is routine on the VA side may be non-formulary (not covered by the approved list) or require step therapy (a process where patients must try certain medications before others) under TRICARE, and vice versa.
This matters during transitions from active duty to VA mental health care, chronic pain management, or post-deployment treatment when medication stability is crucial.
Prescriber vs. Dispenser Rules
This is where families encounter the most confusion:
Under the Veteran’s VA pharmacy benefit, a VA pharmacy dispenses medications for VA patients under VA medical care. It generally cannot fill prescriptions written for TRICARE-covered dependents under the Veteran’s VA benefit.
A VA facility (not the Veteran’s VA benefit) can sometimes operate as a TRICARE-participating provider and bill TRICARE, not VA, but that is a distinct pathway under TRICARE rules, not a way for dependents to access the Veteran’s benefit.
According to VA Pharmacy Benefits Management, VA pharmacies dispense medications in accordance with VA care and eligibility criteria.
Refill Timing and “Refill Too Soon” Logic
VA encourages Veterans to request refills roughly 10–15 days before they will run out, given standard mail delivery timelines. TRICARE Home Delivery, a service provided by Express Scripts that delivers medications directly to beneficiaries, typically authorizes a refill when about 25% of a 90-day supply remains. This means beneficiaries are encouraged to place orders when about two weeks of medication remain.
Families trying to synchronize refills before a PCS, school medication check, or travel period often discover that the two systems cannot be aligned.
Why the Pharmacy Gap Matters Clinically
The pharmacy gap affects:
- Mental health medication stability
- ADHD school accommodations
- Diabetes and insulin control
- Seizure and migraine management
- Post-service continuity of therapy
- Medication reconciliation across prescribers
VA and DoD improved electronic health records, but pharmacy integration remains fragmented. Home delivery, VA, MTF, civilian prescribers, and Medicaid all operate separately.
What Families Can Do Within the Current System
Veterans and spouses report better prescription stability when they:
- Keep a written list of all medications, prescribers, dispensing locations, and payers
- Request continuity-of-therapy considerations during transitions
- Expect staggered refills rather than synchronized refills
- Verify cold-chain handling before moving or traveling
- Clarify primary vs. secondary insurance rules before retail fills
Why the Gap Exists and Why It Hasn’t Been Resolved
VA PBM and TRICARE pharmacies operate under separate statutory authorities, governance structures, and PBM contracts. VA PBM reports through VA’s health system. TRICARE pharmacy operations report through DHA and a civilian PBM contract. CHAMPVA uses mail-order for eligible beneficiaries without other prescription coverage. Medicaid pharmacy benefits operate at the state level.
No federal program currently integrates these benefits into a unified household pharmacy framework because they weren’t designed to converge at the family level.
Until that changes, mixed VA/TRICARE families will continue reconciling these systems manually, even though both programs are funded by the taxpayers they serve.
