Medicare Annual Notice of Change: What the ANOC Means

An Annual Notice of Change, or ANOC, is the letter your Medicare Advantage or Part D plan sends every September explaining what will change on January 1. Reading it is the first step to knowing whether your plan still fits.

What Is a Medicare Annual Notice of Change (ANOC)?

An Annual Notice of Change is the document your Medicare Advantage or Medicare Part D plan sends each fall explaining what will change about your coverage on January 1 of the following year. Medicare says members should receive it in September.

It may show changes to:

  • Monthly premiums, deductibles, copays, and coinsurance
  • Prescription drug coverage, formularies, and pharmacy networks
  • Medical benefits and provider networks
  • Dental, vision, hearing, OTC, transportation, and other extra benefits
  • Prior-authorization or other plan rules
  • The plan's maximum out-of-pocket limit

Compare your ANOC with your current coverage to see whether the plan will still meet your medical, prescription, and financial needs. Changes can be made during the Medicare Annual Enrollment Period, October 15 through December 7, for coverage beginning January 1. CMS specifically encourages members to review both their ANOC and their Evidence of Coverage each year.

What Should You Do When You Get Your ANOC?

Read through it with your own situation in mind — not just the plan's summary. Here's what to look at first.

Financial Changes

Check whether your monthly premium is going up, whether deductibles or copays are increasing, and whether the plan's maximum out-of-pocket limit has changed.

Medical Networks

Confirm your primary doctors, specialists, and preferred hospitals are still in the plan's network, and that your pharmacy is still a preferred partner for the lowest drug prices.

Prescription Drug Coverage

Check whether your regular medications have moved to a higher-cost tier, and look closely for any drug being dropped from coverage entirely.

Extra Benefits

Look for reductions in dental, vision, or hearing allowances, and check whether OTC allowances are decreasing for the coming year.

Do Nothing

If the changes still work for your budget, doctors, and prescriptions, your plan will renew automatically for January 1. No action is required.

ANOC Questions

A Medicare Annual Notice of Change, or ANOC, is a letter your Medicare Advantage or Medicare Part D plan sends each fall explaining what will change about your coverage on January 1 of the following year, including costs, benefits, and network or formulary changes.
Medicare says plans should send the ANOC to members in September, ahead of the Annual Enrollment Period, which runs October 15 through December 7.
Not necessarily. If you review the changes and are comfortable with them, you generally do not need to do anything; your plan will renew automatically for January 1. If your costs are rising or your coverage is shrinking, you may want to compare other options before the Annual Enrollment Period ends.
The ANOC summarizes what is changing for the coming year. The Evidence of Coverage is the fuller plan document describing all of your current benefits and rules in detail. CMS encourages members to review both each year.
No. A Medicare Advantage plan review with Lehigh Partners Senior Benefits has no cost and no obligation to enroll.
