How to recover a Sequestration Over-Applied underpayment

Sequestration is a 2% reduction that applies to Medicare and Medicare Advantage payments. It becomes an underpayment when a commercial payer takes the 2% with no basis, or when it's double-applied.

How it shows up: CARC 253 — roughly a 2% reduction

Why it happens

  • A commercial payer applied sequestration with no contractual basis
  • The 2% was double-taken
  • It was applied to a non-Medicare line
  • The reduction percentage was wrong

What recovers it

  • Confirm sequestration applies only to Medicare and Medicare Advantage, not commercial plans
  • Show the commercial payer has no contractual basis for the reduction
  • Request the 2% back on the commercial lines
  • Verify it wasn't taken twice on the same payment

Worth recovering? Two percent sounds small, but across high claim volume it compounds, and a commercial payer applying sequestration at all is frequently a clean, plainly recoverable error.

Common questions

How do I recover a Sequestration Over-Applied underpayment?

Sequestration is a 2% reduction that applies to Medicare and Medicare Advantage payments. It becomes an underpayment when a commercial payer takes the 2% with no basis, or when it's double-applied. To recover it: confirm sequestration applies only to Medicare and Medicare Advantage, not commercial plans; show the commercial payer has no contractual basis for the reduction; request the 2% back on the commercial lines; verify it wasn't taken twice on the same payment. Because the claim already paid, the hard part is catching it, reconciling the allowed amount against what you were actually owed.

Is a Sequestration Over-Applied underpayment worth recovering?

Two percent sounds small, but across high claim volume it compounds, and a commercial payer applying sequestration at all is frequently a clean, plainly recoverable error.
