Medicare Sequestration: 2% Payment Reduction

Written by Barley Billing Team, Medicare Billing Experts | Last reviewed March 26, 2026

Does your notice say something like this?

"Sequestration - reduction in federal payment"

"Payment reduced per sequestration guidelines"

If so, you're in the right place. Here's what it means and what to do.

What This Means

You may have noticed a line on your Medicare Summary Notice (MSN) or your provider’s bill showing a small reduction labeled “sequestration.” This is a 2% cut to what Medicare pays your provider or supplier. It is not a denial of your claim. Your service was still covered.

This reduction affects the provider’s payment, not your share of the costs. Your deductible, coinsurance, and copayment amounts stay the same.

Why This Happens

Should You Appeal?

Appeal outlook: Not applicable
Sequestration is not a denial. It is a mandatory federal budget reduction that applies automatically to all Medicare fee-for-service payments. There is nothing to appeal because your claim was processed and paid — just at a 2% lower rate to the provider.

What To Do Next

  1. Check that you are not being billed for the 2%. If your provider accepts Medicare assignment (and most do), they cannot pass the sequestration reduction on to you. Your cost-sharing amounts (deductible, coinsurance, copayments) should not change because of sequestration.
  2. If a provider bills you for the sequestration amount, contact their billing office and explain that the sequestration reduction is the provider’s contractual adjustment, not a patient responsibility. Providers who accept assignment agree to accept Medicare’s payment (after sequestration) as payment in full.
  3. Look at your MSN or Explanation of Benefits. The sequestration reduction typically appears as adjustment code CO-253 with the description “Sequestration — reduction in federal payment.” The “CO” prefix means “Contractual Obligation,” which means the provider must absorb this amount.
  4. If you believe you’re being incorrectly billed, contact 1-800-MEDICARE (1-800-633-4227) to report the issue, or contact your State Health Insurance Assistance Program (SHIP) for free help.

Frequently Asked Questions

What is sequestration?
Sequestration is an automatic 2% cut to Medicare payments required by the Budget Control Act of 2011. It reduces the amount Medicare pays to providers and suppliers, not the amount you owe. It has been in effect since April 2013.
Can my doctor bill me for the 2% reduction?
No. If your provider accepts Medicare assignment, they cannot bill you for the sequestration reduction. This is a cut to what Medicare pays the provider — it does not change your deductible, coinsurance, or copayment amounts. If a provider tries to bill you for this amount, that is incorrect.
Can I appeal the sequestration reduction?
No. Sequestration is a mandatory federal budget reduction that applies to all Medicare fee-for-service claims. It is not a coverage denial and cannot be appealed. It is simply a 2% reduction in what Medicare pays the provider.
Will sequestration end?
Sequestration has been extended multiple times since 2013. Congress can change or end it through legislation, but as of early 2026, the 2% reduction remains in effect. Future budget actions could potentially increase or decrease this amount.
