Denied today. Paid without touching it.

Sirrus takes a denied claim from payer intake to recovered cash with no human intervention. It ingests the denial, selects the right motion, assembles the evidence bundle, executes the submission, runs follow-up over weeks, and closes only when payment posts on the remit.

On standardizable denials, it replaces the analyst and collector completely. Humans only enter when Sirrus flags a real exception — missing evidence, clinical conflict, or a contract dispute that requires legal review.

How it works

The autonomous loop: intake, execute, recover.

Sirrus owns the denial from payer signal to cash confirmation. No analyst queue, no manual packet-building, no status chasing. The platform handles the full operating motion and escalates only true exceptions.

01

Ingest and classify

Sirrus reads 835 remittance data, CARC / RARC codes, portal notices, and UM decisions — normalizes them into a structured case object, and selects the right operating motion without an analyst.

02

Assemble and execute

The platform pulls the exact evidence bundle, generates a payer-ready package, gates for completeness, and submits through the right channel with proof of submission retained.

03

Follow up and recover

Spaced status checks, call work, and supplemental releases run over the full review window. The case closes only when reprocess and payment are confirmed on the remittance.

Real payer intake

Sirrus ingests 835 remittance data with CARC / RARC codes, portal denial notices, UM determinations, and claim-status responses without waiting for an analyst to re-key the case.

Source-grounded fact assembly

Orders, clinical notes, auth traces, claim history, contract terms, and EOB copies are bundled into a single grounded case object — no manual packet-building.

Recovery confirmation

Sirrus closes the loop by detecting reprocessing on the remit, reconciling the recovery against the original balance at risk, and documenting the full audit trail.

Live demo case

Medical necessity denial worked autonomously from intake to recovered cash.

This case is built like a real provider-side denial motion. Sirrus does not just generate a letter — it constructs the full case, maps policy and contract logic, submits the motion, follows the payer through the review cycle, and closes only when payment lands.

Human only if flagged

  • Missing or conflicting authorization evidence across systems
  • Low-confidence clinical rationale after policy and plan comparison
  • Peer-to-peer request or atypical medical-director escalation
  • Contract language conflict that requires payer-specific legal review
  • Attachment completeness failure before release

What Sirrus found that helped overturn

  • The payer denial carried CARC 50, but the clinical record satisfied every element the payer policy lists as required for IMRT coverage of a head-and-neck indication — making the denial procedurally unsustainable.
  • The authorization trace covered the same episode and treatment dates, eliminating the risk that this was an authorization mismatch disguised as a clinical denial.
  • The inverse plan and DVH package documented organs-at-risk sparing that a conventional or 3D technique could not achieve at the prescribed dose and fractionation — directly addressing the standard IMRT medical necessity threshold.
  • Claim lines, units, CPT codes, and dates of service reconciled to the treatment course with no duplicate, bundling, or billing-variance issues identified before release.

Re: First-Level Reconsideration — Medical Necessity Denial, Intensity-Modulated Radiation Therapy (IMRT) — Claim #1842401907

This first-level reconsideration is submitted on behalf of Regional Medical Center by their revenue cycle team. We request immediate reversal of the medical necessity denial and full reprocessing of the above claim. This package includes the denial artifact, supporting clinical records, claim and authorization timeline, and the payer-specific routing documentation applicable to this reconsideration.

Request for full overturn

Regional Medical Center requests immediate reversal of the medical necessity denial and reprocessing of the above claim. This motion is grounded in the source clinical record, claim history, authorization trace, payer denial notice, and the applicable provider-appeal and IMRT policy framework mapped to this case. A written response is requested within the timeframe specified in the provider agreement and applicable state prompt-payment regulations.

Clinical and claim summary

The denied account reflects definitive radiation treatment for oropharyngeal squamous cell carcinoma (ICD-10 C10.9) with bilateral neck coverage. The record contains the radiation oncology consult, physician order, simulation note, inverse-planned IMRT treatment plan, dose-volume histogram set, and the signed course prescription showing total dose and dose per fraction across the treatment dates listed above. The claim history, billed units (CPT 77301; CPT 77385 × 33), and dates of service reconcile to the treatment course. No duplicate, bundling, or timing variance was identified in the pre-release claim audit.

Why the denial is incorrect

First, the payer IMRT coverage policy lists head and neck cancers — including oropharyngeal primaries — as covered indications for definitive IMRT when the clinical record supports medical necessity. Second, the attached documentation satisfies every element the policy requires: confirmed diagnosis, delineated target volumes, total dose, dose per fraction, inverse-planning method, and a narrative statement explaining why IMRT is required over conventional or 3D conformal radiation therapy. Third, the comparative planning evidence demonstrates that the organs-at-risk constraints for this case — parotid glands, spinal cord, and mandible — cannot be met at the prescribed dose with a non-IMRT technique. Fourth, the CARC 50 denial cannot be sustained on clinical or administrative grounds: authorization was in place, claim lines reconcile to the treatment course, and no coverage exclusion applies to this diagnosis or treatment setting.

Contract and process crosswalk

This reconsideration was submitted through the payer's first-level reconsideration channel in accordance with the provider agreement and applicable administrative guide. Claim identifiers, dates of service, billed amount, and reason for disagreement were populated per payer instructions. The denial notice, EOB copy, and supporting clinical and administrative records were attached prior to release. In production, Sirrus binds this section to the live provider agreement, state-specific dispute instructions, and plan-level administrative guide associated with the account.

Requested relief and next steps

Please overturn the denial in full, reprocess the claim consistent with the submitted records, and issue corrected payment for CPT 77301 and CPT 77385 × 33. If any additional clinical or administrative documentation is required, please identify it specifically in your written response. Any supplemental documentation request will be fulfilled promptly — the submitting platform retains all supporting records and can release a supplemental packet without delay. If this reconsideration is denied in whole or in part, please provide the specific clinical rationale and policy basis for each denied service so that a formal second-level appeal or external review request can be prepared.
