CBCS Denial Management and Appeals 2 — Questions and Answers
Question 1: What is the first step a medical biller should take upon receiving a claim denial?
- Immediately write off the denied amount
- Identify the denial reason code and determine whether the denial is correctable, appealable, or valid (Correct answer)
- Resubmit the claim without changes
- Contact the patient to collect the balance
Correct answer: Identify the denial reason code and determine whether the denial is correctable, appealable, or valid
Upon receiving a denial, the first step is to review the reason/remark codes on the remittance advice to understand why the claim was denied and determine the appropriate course of action.
Denial management workflow: (1) Identify denial reason using CARC (Claim Adjustment Reason Code) and RARC (Remittance Advice Remark Code) from the ERA/RA, (2) Determine if denial is clinical (medical necessity, authorization), administrative (timely filing, eligibility), or technical (wrong code, missing information), (3) Assess if correctable (resubmit) or must be appealed, (4) Take appropriate action within the appeal deadline. Tracking denial trends by code helps identify systemic issues to correct at the front end.
Question 2: What is the difference between a claim denial and a claim rejection in terms of next steps?
- Denials require a new claim number; rejections use the original claim number
- Denied claims require a formal appeal through the payer's process; rejected claims are corrected and resubmitted as a new claim (Correct answer)
- Denials can only be handled by the provider; rejections can be handled by billing staff
- There is no practical difference in next steps
Correct answer: Denied claims require a formal appeal through the payer's process; rejected claims are corrected and resubmitted as a new claim
A rejected claim was never processed — correct the errors and resubmit as a new claim. A denied claim was processed and requires a formal appeal through the payer's established appeals process.
For rejections: identify the error (from 277 transaction or clearinghouse report), correct the data in the practice management system, and resubmit. Timely filing deadlines continue running during the correction period. For denials: review the payer's appeals process (level 1 appeal to payer, then external review if applicable), gather supporting documentation, write a formal appeal letter with clinical justification, and submit within the appeal deadline (typically 60–180 days from denial date, payer-specific). Track appeal outcomes to measure denial resolution rates.
Question 3: What is a peer-to-peer review in the context of insurance denials?
- A review of a coder's work by a fellow credentialed coder
- A physician-to-physician discussion between the treating provider and the payer's medical reviewer to discuss a denied or potentially denied service (Correct answer)
- A review process where two insurance companies assess the same claim
- An audit where multiple billers review each other's work for quality
Correct answer: A physician-to-physician discussion between the treating provider and the payer's medical reviewer to discuss a denied or potentially denied service
A peer-to-peer review involves direct physician communication between the treating provider and the insurance company's medical director to discuss medical necessity for a denied or precertification decision.
Peer-to-peer reviews are typically requested within a short timeframe after a medical necessity denial (usually 5–14 days). The treating physician (or their PA/NP in some cases) speaks directly with the payer's medical reviewer to present clinical rationale. This can result in the denial being overturned before going through the formal written appeals process. Peer-to-peer reviews are particularly useful for prior authorization denials, urgently needed services, and complex clinical situations. Billing staff facilitate these calls by obtaining the denial details and scheduling the review.
Question 4: What information should be included in a formal appeal letter for a denied claim?
- Only the claim number and date of service
- Patient information, claim details, denial reason, clinical documentation supporting medical necessity, applicable policies/guidelines, and a specific request for reconsideration (Correct answer)
- Only the physician's letter explaining why the service was necessary
- The patient's complaint about the denial
Correct answer: Patient information, claim details, denial reason, clinical documentation supporting medical necessity, applicable policies/guidelines, and a specific request for reconsideration
A complete appeal letter includes patient and claim identification, the specific denial reason being appealed, supporting clinical documentation, references to clinical guidelines, and a clear request for the specific action sought.
Effective appeal components: (1) Cover letter with patient name, DOB, member ID, date of service, claim number, denial date, and denial reason code, (2) Statement of the issue and requested outcome, (3) Clinical documentation (progress notes, operative reports, lab results), (4) Letter of medical necessity from the treating provider, (5) References to evidence-based guidelines (CMS coverage determinations, clinical society guidelines), (6) Applicable policy language, (7) Deadline awareness. Organize documentation clearly; payers review hundreds of appeals — clarity matters.
Question 5: What is a corrected claim and when is it used?
- A new claim submitted after a denial, used instead of an appeal
- A resubmission of a previously processed claim with corrections to errors, submitted with frequency code 7 (replacement) or 8 (void) (Correct answer)
- A claim submitted on paper to replace an electronic claim
- A claim submitted by the patient after the provider declines to refile
Correct answer: A resubmission of a previously processed claim with corrections to errors, submitted with frequency code 7 (replacement) or 8 (void)
A corrected claim replaces a previously processed (paid, denied, or partially paid) claim to fix billing errors. It is identified with bill type frequency code 7 (replacement) or 8 (void/cancel) on institutional claims, or with condition code on professional claims.
Corrected claims are used when: coding errors were made, the wrong patient information was submitted, the wrong service dates or procedure codes were entered. For CMS-1500/professional claims: resubmit with the original claim number in Box 22 (Resubmission Code 7=replacement, 8=void). For UB-04/institutional claims: use Type of Bill frequency digit (7=replacement, 8=void). Corrected claims must be submitted within the payer's timely filing limit. Do not submit corrected claims for denials — use appeals. Do not submit a new claim when correcting an error — use the correct resubmission code.
Question 6: What is the Medicare redetermination process?
- A Medicare audit process for identifying fraud
- The first level of Medicare's five-level administrative appeals process, where the Medicare Administrative Contractor reviews the claim denial (Correct answer)
- A process for reviewing Medicare premium calculations
- A secondary billing process for Medicare crossover claims
Correct answer: The first level of Medicare's five-level administrative appeals process, where the Medicare Administrative Contractor reviews the claim denial
Medicare redetermination is the first level of appeal, filed with the Medicare Administrative Contractor (MAC) within 120 days of the initial determination. The MAC reviews the claim and makes a new determination.
Medicare's five-level appeals process: Level 1 = Redetermination (MAC, 120-day deadline, decision within 60 days), Level 2 = Reconsideration (Qualified Independent Contractor/QIC, 180-day deadline from Level 1 decision), Level 3 = Administrative Law Judge (ALJ) hearing (at HHS OMHA, 60-day deadline from Level 2), Level 4 = Medicare Appeals Council (DAB, 60-day deadline from Level 3), Level 5 = Federal District Court (for claims meeting amount-in-controversy threshold). Most denials are resolved at Level 1 or 2. Understanding this process is critical for effective denial management.
