Lesson 4 of 5

Corrected Claims, Appeals and Timely Filing

The right response to a denial depends on the reason. A corrected claim fixes supported claim data; an appeal challenges an adjudication decision using the payer's required process and evidence.

Beginner20-24 minFree lesson

Corrected claim

A corrected claim is generally appropriate when information on the original claim was wrong or incomplete and the payer instructs the provider to submit a corrected or replacement claim. The correction should reflect verified source information and the payer's submission rules.

Appeal

An appeal asks the payer to reconsider an adjudication decision. Appeals commonly require a written or electronic explanation plus supporting documentation, and they must follow the payer's designated level, format and deadline.

Correct

Use when supported claim information needs to be fixed and the payer accepts a corrected-claim workflow.

Appeal

Use when the provider disputes the payer's adjudication and can support the request with relevant facts or documentation.

Other process

Some payers use reconsideration, reopening, dispute or resubmission workflows. Follow payer instructions.

Deadlines matter

Timely-filing and appeal limits vary by payer, contract, product and situation. Record the applicable deadline when the denial is identified. Keep proof of original submission and payer acceptance when filing history could matter.

Medicare example

For Original Medicare fee-for-service, CMS states that a first-level redetermination is generally requested within 120 days of receipt of the initial determination. Medicare claim timely filing is generally 12 months from the date of service, subject to specific rules and exceptions. Other payers may use different limits.

Build the submission package

  • Correct patient, claim and payer identifiers.
  • The exact denial or adjustment being addressed.
  • A concise explanation of the requested action.
  • Relevant medical record, authorization, eligibility, claim history or other supporting evidence.
  • Proof of timely submission when relevant.
  • Correct payer form, portal workflow or address.
Do not assume one deadline fits every payer. Always verify the payer-specific filing or appeal requirement for the claim involved.
