CMS-1696 Appointment of Representative Form: What Caregivers Need to Know

You hold your parent's durable power of attorney, you've managed their finances for two years, and you call their Part D plan to dispute a pharmacy denial. The representative tells you they can't discuss the account with you. Your POA doesn't matter.

This happens constantly, and it's not a mistake. Federal agencies operate under their own statutory frameworks. Medicare, Social Security, and private Part D plan sponsors each require separate authorization forms — and a state-issued power of attorney doesn't satisfy any of them.

Why a Power of Attorney Isn't Enough

A durable power of attorney is a state-level legal document that grants authority under state law. It's essential for banking, real estate, and many healthcare decisions. But Medicare is a federal program administered by CMS, and CMS has its own rules about who can act on a beneficiary's behalf.

The disconnect catches caregivers at the worst possible moment: at the pharmacy counter when a drug is denied, during a coverage appeal with a 65-day filing deadline, or when trying to compare plans on Medicare.gov during open enrollment.

What Form CMS-1696 Does

Form CMS-1696 — the Appointment of Representative — is the official federal form that authorizes a caregiver to act on a parent's behalf in Medicare matters. Once filed, it lets you:

• Request coverage determinations and formulary exceptions from the Part D plan
• File appeals at all five levels of the Medicare appeals process
• Access your parent's coverage information and claims history
• Choose, change, or disenroll from Part D plans
• Communicate with the plan sponsor about pharmacy disputes

Both the beneficiary (your parent) and the appointed representative (you) must sign the form. If your parent is cognitively impaired and unable to sign, you'll need a court-appointed guardian or a healthcare proxy recognized under your state's laws — the POA alone won't work for CMS-1696 either in that situation.

How to File

1. Download Form CMS-1696 from the CMS forms page (search "CMS-1696" at cms.gov/forms).
2. Fill in Section 1 with your parent's Medicare information and Section 2 with your information as the representative.
3. Both parties sign and date the form.
4. Submit a copy to each entity where you need authorization: the Part D plan sponsor, any Medicare Administrative Contractor (MAC) involved in a claim, and CMS directly if you're filing a Level 3+ appeal.

There is no single central filing — each plan sponsor and Medicare contractor requires their own copy. Keep multiple signed originals.

The Full Authorization Stack

CMS-1696 covers Medicare. But if your parent also receives Social Security benefits or you need to manage their Extra Help application, you'll need additional forms:

Form SSA-1696 (Social Security): Authorizes you to act on your parent's behalf with the Social Security Administration — for retirement benefits, survivor benefits, or appealing an Extra Help denial. SSA does not recognize state POA documents.

Plan-Specific Disclosure Forms: Many Part D plan sponsors require their own HIPAA-compliant authorization form in addition to CMS-1696 before they'll discuss prescription details or claims.

Representative Payee Application: If your parent can no longer manage their Social Security payments due to cognitive decline, you must apply separately to become their Representative Payee through SSA. This requires annual accounting of how benefits were spent.

The Timing Problem

Most caregivers don't discover these requirements until they're in a crisis — a drug denial, a hospital discharge, or an enrollment deadline. Filing CMS-1696 takes time: you need your parent's signature, the plan sponsor needs to process it, and if you're mid-appeal, any delay burns into your filing window.

File proactively. If you're helping manage a parent's Medicare coverage, submit CMS-1696 to their Part D plan now — before you need it. Keep a stack of signed originals in your files so you can submit one immediately to any new entity.
