Pillpack by Amazon not coordinating with Medicare Part D

PillPack Medicare Part D problems usually come down to one thing: the pharmacy can’t bill your plan correctly, so your order gets held up. If your pack isn’t shipping, don’t guess—follow these steps in order to find the exact snag.

Start here: confirm the plan and network

Before making changes in PillPack, call your Medicare drug plan (the number on your Part D card) and ask:

• “Is PillPack in-network for my plan right now?” (Pharmacy networks can change.)
• “Do you require a preferred mail-order pharmacy?” If yes and PillPack isn’t the preferred option, billing may fail.

If the plan says PillPack is out-of-network, this isn’t a settings issue. You’ll need to pay more, switch pharmacies, or ask which mail-order option is covered.

Fix the most common mismatch: identity details

This is the #1 real-world blocker. Even a small difference like “Street” vs “St.” can cause a refill hold.

Ask PillPack to read back what they have on file for:

• Full name (including middle initial if used by your plan)
• Date of birth
• Address (exact formatting)
• Phone number (sometimes used for verification)

Compare this to your Medicare prescription plan enrollment details. Correct any differences in PillPack first, then re-run eligibility.

What to do when claims reject

PillPack Medicare Part D billing issues

If PillPack says “insurance won’t go through,” ask for the reject reason in plain language. Common fixes include:

• Prior authorization needed: Call your doctor to submit the authorization to your plan.
• Refill too soon: Ask PillPack for the next fill date or inquire about a vacation override if you need it early.
• Drug not covered / needs alternative: Ask your plan for covered options and have your doctor update the prescription.
• Quantity limit: PillPack can sometimes rebill for the allowed quantity, or your doctor can request an exception.

Don’t stop at “pending”—get the reason and match it to a fix.

If shipping is stalled even though insurance looks fine

Amazon PillPack Medicare prescription delays

Once eligibility is verified, delays are often operational: missing details, prescriber sent the prescription to the wrong profile, or pharmacist review is pending.

Ask PillPack:

• “Is the prescription marked as received and valid (strength, directions, refills)?”
• “Is anything waiting on prescriber clarification?”
• “What is the estimated ship date, and what task must happen before it ships?”

When PillPack says they can’t take your plan

PillPack not accepting Medicare Part D plan

This is usually network or plan entry related. If your plan confirmed PillPack is in-network, ask them to double-check they didn’t load the wrong insurer.

Also confirm you’re giving the correct card. Many people have separate medical and Part D pharmacy cards. PillPack needs the pharmacy benefit info for Part D coverage.

Clean reset: re-add insurance and transfer correctly

How to transfer Medicare Part D to PillPack

If you recently switched plans (especially around Jan 1), follow a clean reset:

1. Ask PillPack to remove the old insurance entry.
2. Add the new plan with the exact member ID, RxBIN, RxPCN (and group if listed).
3. Ask them to run a test claim while you are on the phone.

If you’re at risk of running out, ask your plan which local pharmacies are in-network for a short fill while PillPack Part D is sorted.
