Denials: classification, appeal rights and deadlines

3 min read

The first decision after a denial is not whether to appeal. It is what kind of denial this is, because several categories look identical in a letter and have completely different remedies. Appealing an administrative denial is slow, expensive and unnecessary.

#Classify first

Category	What happened	Remedy
Administrative	A field was wrong or missing: member id, provider identifier, an invalid code.	Correct and resubmit. This is not an appeal and treating it as one wastes weeks.
Eligibility	Coverage was not active, or not active on the service date.	Verify coverage. Often the real answer is a different payer, or a coordination of benefits order nobody checked.
Benefit exclusion	The plan does not cover this service at all.	An appeal on medical necessity cannot win. The argument, if there is one, is about the exclusion or about the patient's financial responsibility.
Not medically necessary	The clinical case did not meet criteria.	Peer-to-peer if still available, then formal appeal. This is the category appeals exist for.
Documentation	Records were requested and not received, or were insufficient.	Send what was asked for. Frequently a fax that never arrived rather than a clinical disagreement.
Wrong reviewer	The service is delegated and went to the plan instead.	Resubmit to the delegated reviewer. See Delegated utilization management.

The specific reason matters and is now required

Under CMS-0057-F, impacted payers must include a specific reason when denying a prior authorization request, explicitly so that resubmission or appeal is possible rather than guesswork. Where you get a vague reason from a payer within scope, asking for the specific one is reasonable and is what the rule contemplates.

#Appeal levels

Reconsideration or first-level internal appeal
The plan reviews again, generally with a different reviewer. This is where new clinical information belongs. An appeal that resubmits the same packet usually gets the same answer.
Second-level internal appeal
Where the plan offers one. Availability varies by plan type and by state.
External review
An independent organisation not employed by the plan. Available for most plans, with the route depending on whether the plan is state-regulated or governed by ERISA. This is a genuine check and plans lose a meaningful share of them.

Expedited appeals exist and are underused

Where delay would seriously jeopardise the patient, an expedited appeal compresses the timeline substantially. It requires a clinical assertion that the standard timeline is harmful, which should be made when it is true and not routinely.

#Deadlines are strict

Appeal windows are measured from the date of the determination notice and they are enforced. A strong clinical case filed late is a lost case. The date on the letter is the date that matters, not the date somebody noticed it, which is an argument for the denial reaching the person who acts on it the day it arrives.

#Track the pattern, not just the case

Individual appeals are a cost of doing business. A pattern is information. If one payer denies the same procedure repeatedly for the same reason, the answer is not a better appeal template, it is reading that payer's policy for that procedure and changing what the practice documents.
