1. The determination being appealed
Quote the payer’s own codes back to them: group code, reason code and its published description, remark code and its published description, and the policy the remittance named.
2. What we are asking for
One sentence, before the argument. Reprocess and pay at the contracted rate. Reverse the edit on line three. Honour the authorization.
3. Why the determination should be reversed
Documentary where the denial is administrative. Against the payer’s quoted criteria where it is a coverage decision.
4. Clinical statement
Completed and signed by the treating clinician
The payer’s criteria for this service are listed here, quoted from the policy. The argument that this patient met them is not drafted for the clinician, and the appeal is not sendable while this block is empty.

Clinician name, credentials, NPI
5. Enclosures
Numbered to match the references in the body.
A denied claim arrives as a code, not as a sentence. Somewhere on the remittance is a two letter group code, a numeric reason code, and usually a remark code, and those three fields decide whether you are looking at a resubmission, a real appeal, or a write off. Most appeal templates skip past all of that and hand you one letter with a blank where the denial reason goes. This pack starts where the payer actually spoke.
So the register is built by service line rather than by claim, because one claim can carry two reason codes with two different answers. The reason code says what the objection was. The remark code usually says whether it is fixable, which is why a claim adjustment reason code 16 arriving with no remark code is a question for the payer instead of a guess, since the code list itself requires one. And the tracker dates every deadline from the clock that payer actually runs on, because Medicare and an ERISA plan are not close.
Take a reason code 197 denial, precertification absent, on a claim where the authorization did exist. Before anything gets written, the register asks whether it was issued against the NPI, the site and the date range that were actually billed. When it was not, this is a documentary appeal with one exhibit rather than a clinical argument. Open the pack in River and the agent decodes your remittance and fills the register. Or download the blank Word and CSV files and work it wherever you already do.
What's in the pack
Denial Register
One row per denied service line, decoded by group, reason and remark code, with the appeal or resubmit call recorded. A PR group line is not an appeal at all, it is a patient balance, and it leaves here for the patient billing pack.
Appeal Letter
The full letter structure, with the clinical statement left as a signed block the treating clinician fills in.
Payer Appeal Profile
Where this payer wants appeals sent, on what clock, with which form, sourced field by field.
Reason Code Playbook
What actually worked against each code pair at your practice, written from closed appeals rather than a generic list.
Appeal Tracker
Every appeal in flight with its deadline, the clock it runs on, and what the filing is waiting on.
Supporting Documentation Checklist
What goes in the envelope, by denial type, so the packet is built from the code rather than the chart.
Escalation Path
The five level Medicare ladder and the ERISA 180 day floor written out, so an upheld appeal has a dated next level.
Outcome by Reason Code
Counts by payer and code pair, so next quarter you know which appeals are worth filing at all. That per-payer recovery rate is also the input the revenue cycle metrics pack needs to turn a denial rate into a cash figure.
How to use it
- 1
Open in River, or download it
Open the pack in River and let the agent work your queue, or download the blank Word and CSV files instantly.
- 2
Send a remittance
In River, the AI decodes every denied line from an 835, an ERA export, a paper remittance or a photographed denial letter. Working from the download, fill the register by hand.
- 3
Learn your payers once
Run the payer playbook with a denial letter in hand and the profile fills with their deadline, their clock, their form, and their appeal address.
- 4
Draft, file, and close the loop
Write the appeal against the code the payer sent, hand the clinical block to the clinician, then record what came back so the next one is faster.
Frequently asked questions
Is this template free?
Yes. Download the whole pack as Word documents and CSV sheets with no signup and no credit card. "Edit with AI" is a separate, optional path for practices that want the agent to decode a remittance and draft from it. Other packs are in the template library.
What format are the downloaded files?
Word documents (.docx) for the letter, checklist, payer profile, playbook and escalation path, and CSV (.csv) for the three tracking sheets, zipped into one file. They open natively in Word, Pages, Google Docs, Excel, Numbers and Sheets, with nothing to convert.
Does it write the medical necessity argument?
It does the part that takes the time. It pulls the payer's criteria out of the policy the remittance named and lays them out as a checklist, so the clinician writes to that payer's standard in minutes instead of freehand. The signature and the clinical judgement stay theirs. When the packet needs the underlying note, that is the clinical documentation workspace.
How does it know my payer's appeal deadline?
It does not, until you tell it or it reads a denial letter from them. The payer profile is built from that letter's appeal rights paragraph and the payer's published policy, with the source recorded against each field. Anything it cannot source stays blank rather than guessed.
Will it tell me which denials to appeal and which to resubmit?
Yes, and that call comes from the remark code rather than the reason code. A submission defect with a remark code naming the field is a corrected claim, which is faster and does not consume an appeal level. Filing the wrong one costs a cycle. To make that call across a whole remittance, triage the remittance file and work the queue it ranks.
What does 'Edit with AI' actually do?
It creates a free River account, installs this exact pack as a private workspace, and opens it ready to read whatever you send: an 835, an ERA export, a scanned remittance, a denial letter. Nothing is written until you send it something.
Who is this pack for?
Billers, practice managers and small revenue cycle teams who work their own denial queue. It assumes you receive remittances and can reach your payers' portals. A two-provider practice gets the same value as a forty-provider one, since the payer profile and reason code playbook fill from whatever volume you have. Remittance and denial triage works the wider queue, not just the appeals in it.
