Documentation & coding
From op note to clean claim, the same day
The claim is decided in the OR — what was documented, what was used, what the codes can support. Perivanta checks all of it while the case is hours old, so problems get fixed in minutes instead of surfacing as denials weeks later.
Perivanta is in development with founding design partners — this page describes the capability we’re building together.

The claim is decided in the OR, not the billing office
Most ASCs still run documentation and billing as a relay race: the case happens, the chart gets finished later, charges get entered after that, and a biller submits the claim days downstream. Every handoff is a place where documentation gaps, coding mismatches, and unbilled implants slip through — and the context needed to fix them fades with each day.
By the time a denial or an audit finds the problem, the case is weeks old. For a high-volume center the accumulated leakage — incomplete op notes, missed charges, codes the documentation can't support — quietly compounds into real money and rework.
What Perivanta does between case and claim
Perivanta carries the full case record — what was scheduled, authorized, performed, and used — into the post-case check, so nothing has to be reconstructed from memory.
Documentation completeness checks
Compares the op note against the performed procedure — laterality, implants, approach — and flags what's missing while the surgeon still remembers the case.
Coding validation
Checks that the codes are supported by what was actually documented, against payer-specific rules — before submission, not in an appeal.
Charge reconstruction
Cross-references implants and supplies used in the case against the claim, and adds what was used but never charged.
Scheduled-vs-performed reconciliation
Catches the case where what was authorized, performed, documented, and coded don't agree — the mismatch behind a large share of preventable denials.
Same-day claim readiness
Tracks each case from completion to clean claim and does the chasing in between, so days-to-bill is an outcome, not an aspiration.
Coder exception workspace
Coders see the cases that need judgment, with the evidence assembled — the note, the auth, the charges — instead of digging through charts to find the question.
Built to make your billing team faster, not replace it
Coding authority stays with your coders and your compliance policies; clinical documentation stays in your EHR or ASC management system as the legal record of care. Perivanta checks, reconstructs, and prepares — your team decides.
Whether you bill in-house or through an RCM partner, whoever submits your claims starts from complete documentation and complete charges, with every fix traceable to its evidence.
Common questions
- Does this replace our biller or RCM company?
- No. Perivanta works upstream of submission — completeness, coding support, and charges — and hands whoever bills for you cleaner input. Fewer denials and faster payment follow regardless of who submits.
- Where does the documentation live?
- In your existing EHR or ASC management system. Perivanta reads and analyzes the record and writes its findings back through auditable workflows; your system of record remains the legal record of care.
- Does Perivanta submit claims itself?
- Under your policy, it can — automation expands in stages, from preparing claims for review to submitting routine ones automatically and escalating exceptions. You decide which actions run on approval and which run on autopilot.
- What causes most ASC claim denials?
- The recurring culprits are incomplete operative documentation, codes that don't match what was documented, authorization mismatches, and payer-specific submission rules. All are cheapest to fix on the day of the case — which is exactly when Perivanta checks for them.
