HCR/203: Medical Claims Processing and Compliance

Week 4 Assignment

[Instructor Name]

[Date]

The billing company, its clients and the claims are composites written for a model paper; appeal rules and thresholds come from the sources listed.

Every Monday, specialists at the billing company introduced earlier in the course review a denial report for its six physician practices and a critical access hospital, sorted by reason and dollar value. Last month, 6.1% of claims were denied on first submission and another 2.3% were rejected before processing. This paper follows three unpaid claims from one week's report to explain rejections, denials and appeals.

Rejections and Denials

A rejection happens before processing: the clearinghouse or payer's front-end edits find missing or invalid data and return the claim. It has not been adjudicated, so it can be corrected and resubmitted with no appeal. A denial happens after processing: the payer adjudicated the claim and refused to pay all or part of it. A denial is reported on the remittance advice with a group code and a claim adjustment reason code from the standard list (X12, n.d.).

Claim One: A Rejected Claim

An orthopedic practice's claim came back from the clearinghouse with an error indicating the subscriber could not be identified. The specialist compared the claim with the scanned insurance card and found two digits of the member number transposed at registration. She corrected the number and resubmitted the claim the same morning. It was paid 14 days later. Because it was a rejection, no timely filing clock was threatened, but a claim left in the rejection queue for weeks can miss a payer's filing deadline.

Claim Two: A Medicare Denial Fixable by Correction

A family practice billed an office visit and a knee joint injection for the same Medicare patient on the same day. The visit line came back denied with group code CO and a reason code for a service included in the payment for another service billed that day. The specialist read the note: the physician had injected the knee as planned and had also evaluated and changed treatment for the patient's worsening heart failure, a separate problem documented in its own assessment. The visit was separately payable, but the claim lacked modifier 25 to say so. The denial came from the claim, not from a payer mistake, so the right response was a corrected claim adding the modifier, which the contractor paid, rather than an appeal. Appealing a denial you caused wastes weeks; correcting it wastes minutes.

Claim Three: A Commercial Denial Worth Appealing

A hospital outpatient MRI was denied for lack of prior authorization. The hospital's scheduling notes showed that the ordering practice had obtained approval by phone, with an authorization number, date and call reference. The payer's system had not linked the authorization to the claim. Because the payer's decision was wrong, the specialist filed a written appeal within the plan's 180-day limit.

The Appeal Letter

The letter identifies the patient, member number, claim number, date of service, service and denial reason code. It states the disagreement in one sentence: authorization was obtained before the service. It attaches the authorization number, the call reference and a copy of the order and results. It asks for reprocessing and payment and names a contact. The plan overturned the denial in 23 days.

Medicare's Five Levels of Appeal

Medicare fee-for-service appeals follow five levels (Centers for Medicare & Medicaid Services, n.d.). First, redetermination by the Medicare administrative contractor, requested within 120 days of the initial determination. Second, reconsideration by a qualified independent contractor, requested within 180 days of the redetermination decision. Third, a hearing before an administrative law judge in the Office of Medicare Hearings and Appeals, requested within 60 days. Fourth, review by the Medicare Appeals Council, requested within 60 days. Fifth, judicial review in federal district court, filed within 60 days.

Amounts in Controversy for 2026

Some levels require a minimum amount still in dispute, adjusted each year. For requests filed in calendar year 2026, the amount in controversy is $200 for an administrative law judge hearing and $1,960 for federal district court review (Centers for Medicare & Medicaid Services, 2025).

Commercial and Medicare Advantage Appeals

Commercial plans set their own internal appeal levels and deadlines, with external review available under state or federal rules for certain denials. Medicare Advantage plans handle first-level appeals themselves, with independent review afterward. The company's payer grid lists each plan's appeal limits.

Analyzing Denials to Prevent Them

The company tracks denials by reason, payer, client and stage of the cycle. Last quarter, 31% of denials traced to registration and eligibility, 24% to authorization, 22% to coding and pointers, 14% to payer errors and 9% to other causes. Each category gets an owner and a fix: registration training for client front desks, an authorization checklist for imaging and a scrubber rule stopping claims whose service lines point only to external cause or unrelated diagnoses.

A Denial Worklist in Practice

Working denials efficiently depends on order. The company sorts its worklist by the payer's remaining time limit first, then by dollar value, so no appeal is lost to a deadline while specialists chase small balances. Each account note records the reason code, the action taken and the date to check again. Denials from the same cause are worked together: when one commercial plan denied 40 claims in a week for a missing referring provider number after a system change, a single call and a batch correction resolved them all. Specialists also flag denials that look like payer errors to the account manager, who raises patterns with the payer's provider representative.

Measuring Success

The company's targets are a first-pass denial rate under 5%, rejections corrected within one business day and at least 60% of appealed denials overturned. The overturn rate matters: a low rate suggests the team is appealing denials it should correct instead.

Conclusion

Three unpaid claims showed three responses. The rejection needed a same-day correction, the Medicare denial caused by a pointer error needed a corrected claim and the wrong authorization denial needed a documented appeal. Knowing the difference, reading reason codes, following Medicare's five levels and current thresholds and tracking causes to prevent repeats are the core of denial management.
