Real payer intake
Sirrus ingests remits, ERA / 835 signals, portal denial notices, UM determinations, claim-status responses, and correspondence without waiting for an analyst to re-key the case.
Autonomous denial overturn platform
Sirrus runs the denial from payer intake to recovered cash.
Most appeal teams lose time in two places: finding the right facts across fragmented systems, and turning those facts into a consistent, defensible letter that can move a payer to reprocess the claim. Sirrus RCM AI is built to solve both — and then automate the rest.
The platform ingests payer denials, picks the right operating motion, assembles the exact evidence bundle, generates the motion package, submits it through the right payer channel, performs the portal and phone follow-up over the life of the claim, and confirms recovery on the remittance. On standardizable denials, it replaces the analyst and collection motion completely. Humans only enter when Sirrus flags an exception.

Why this lands with health systems
This is not “AI for appeal letters.” It is denial operations automation.
The letter is just one illustration of the product. The value is that Sirrus owns the denial through intake, strategy, evidence assembly, release, follow-up, overturn, and payment confirmation with no human intervention except flagged cases.
What Sirrus automates
The denial work that usually burns analyst hours disappears into software.
Built for revenue cycle leaders who care about the whole operating motion: intake, correct routing, evidence assembly, payer execution, persistence over long review windows, and actual cash recovery.
Correct motion selection
The system selects the right operating motion for the denial: corrected claim, reconsideration, formal appeal, re-open, prior-auth resubmission, peer-to-peer escalation, or contract variance dispute.
Source-grounded fact assembly
Orders, clinical notes, treatment plans, auth traces, claim history, contract terms, fee schedules, EOB / PRA copies, and submission proofs are bundled into a single grounded case object.
Payer-ready release
Sirrus generates the full motion package, compiles the attachment set, gates for completeness, and releases through the right payer channel without manual queue work.
Long-cycle follow-up
The software runs portal checks, call work, resubmissions, medical review follow-up, and timing-based nudges over weeks — not just a one-time letter drop.
Recovery confirmation
Sirrus closes the loop by detecting reprocessing, reconciling the recovery against the original balance at risk, and documenting the full audit trail.
How it works
A complete denial-to-overturn workflow, not a drafting tool.
Every step below is designed to present Sirrus as the autonomous operating layer: it ingests, proves, executes, follows up, and closes the denial rather than stopping after a document is generated.
01
Ingest denial signals
Normalize 835 codes, remits, portal notices, UM decisions, and claim history into one case object tied to the actual account.
02
Score recoverability
Rank the denial by expected recoverability, balance at risk, filing clock, and payer behavior so the right accounts move first.
03
Select the operating motion
Choose reconsideration, appeal, corrected claim, reopen, auth resubmission, peer-to-peer, or contract dispute based on the denial class.
04
Assemble the facts
Collect the exact evidence bundle: claim lines, dates of service, authorization proof, clinical documentation, contract language, and payer instructions.
05
Execute the appeal
Generate the payer-ready package, attach the support set, release it through portal / fax / mail workflows, and retain proof of submission.
06
Run the case through overturn
Perform spaced status checks, call work, supplemental releases, and payment confirmation until the denial is reversed or escalated as flagged.

Grounded case facts
Sirrus turns the rad onc denial into a structured case with the exact records needed to support overturn.
- Medical necessity denial parsed from the payer response and tied to the correct IMRT claim, account, and episode of care.
- Oropharynx and bilateral neck target volumes mapped to the treatment plan, with total dose and dose per fraction aligned to the course summary.
- Inverse-planned IMRT, dose-volume histogram evidence, and narrative need for IMRT versus conventional technique collected into the appeal bundle.
- Authorization history, claim timeline, and submission history aligned to the same dates of service before the motion was released.
- Completeness gate prevented release until the denial notice, EOB copy, comparative planning artifacts, and payer instructions were all present.
Policy / contract match
Clinical policy matchHead and neck cancer / oropharynx fits payer IMRT coverage language for definitive treatment.
Documentation matchDiagnosis, target volume, total dose, dose per fraction, inverse planning method, and narrative rationale attached.
Contract / process matchReconsideration path triggered with claim identifiers, DOS, billed amount, denial copy, and supporting documents.
Release gateNo motion is released unless the attachment set is complete and the filing clock is still open.

What a revenue cycle leader notices
The details that separate a flashy AI demo from a system you would actually deploy.
This build intentionally leans into the operational details revenue cycle teams care about: the right motion type, filing clocks, payer artifact integrity, release completeness, long-cycle follow-up, and confirmation that the recovery actually landed.
Denial intake is artifact-first
The software starts with real denial artifacts — ERA / 835, portal notices, UM decisions, EOB / PRA language, and claim history — instead of a manual work-queue abstraction.
It selects the right motion, not just a letter template
Strong denial automation knows when the answer is a corrected claim, reconsideration, formal appeal, reopen, or auth fix. A generic “write a letter” tool is not enough.
Clinical denials need record logic
For radiation oncology, the system has to understand diagnosis, target volume, treatment plan type, dose / fractionation, auth history, and the payer policy language that governs the review.
Completeness control matters
A missing EOB copy, missing plan comparison, or wrong denial attachment can cost weeks. Sirrus gates release so incomplete packets do not go out.
Follow-up is a calendar problem
Claims often take weeks and multiple inquiries to move. The call log here is intentionally spaced because that is what real denial management looks like.
Recovery is not real until cash lands
Portal “approved” is not the same as reprocessed cash. Sirrus keeps the case alive until the recovery posts and reconciles to the original balance at risk.
