Payer document requests

How do we answer a payer's request for more records by matching it to the case, pulling and checking the documents, and sending the response on the payer's clock?

Treat each payer request as a case with a deadline and a specific list. When a payer asks for additional documentation (on a pended claim, a pre-payment review, a post-payment audit, an authorization), Callvu reads the request and matches it to the patient, the encounter, the claim and the authorization, classifies the request type and the payer's deadline, lists the specific records asked for, pulls them from the EHR and the billing system (or chases a department for what is not filed), checks each against the request (the dates of service, the record type, the completeness, the signatures), masks what the minimum necessary standard excludes, routes an ambiguous request or a record that cannot be found to the revenue integrity or the health information team in the Decision Desk, and sends the response through the payer's channel with what was sent logged against the claim.

The problem today

The payer's request was answered on day thirty-one with the wrong encounter's notes, and the claim denied for untimely documentation.

Today, without Callvu

Payers ask for records constantly: a pended claim wants the operative note, a pre-payment review wants the whole chart, an audit wants a sample of encounters, an authorization wants the clinical criteria evidence. The letters arrive in the mailroom, the fax queue or a portal; someone matches them to a claim by eye; the records are pulled by a department that has forty other requests; the response goes out late or incomplete, and the claim denies or the audit extrapolates.

Each request has a type, a deadline the payer or the regulation sets, a specific list of records, and a channel for the response. The records are in the EHR and the billing system; the minimum necessary standard limits what is sent; the response must be logged because the appeal will depend on proving what was sent and when. The matching and the pulling are rules; the deadline is a clock.

A payer request answered on time with exactly what was asked is a claim that pays.

How it runs

From the requestto the system of record.

A payer's request for records arrives by letter, fax, portal or electronic attachment request. Callvu reads it and opens the case.

Payer: Sends the request and receives the response through its channel.
Health information management and clinical departments: Supply records not filed in the EHR through their links.
Revenue integrity or health information team: Decides ambiguous requests and unfound records in the Decision Desk.
Callvu: Reads, matches, classifies, lists, pulls, chases, checks, masks, routes, sends and logs.

Classify and match
The request is read (the payer, the patient identifiers, the dates of service, the claim or authorization reference, the records requested, the deadline, the response channel) and matched to the patient, the encounter, the claim and any authorization; the request type (pended claim, pre-payment review, post-payment audit, authorization support, coordination of benefits) sets the deadline and the rules.
Chase and verify the records
The specific records are listed and pulled from the EHR and the billing system (the notes, the operative report, the orders, the medication administration record, the itemized bill, the authorization); a record not filed is chased from the department through its link with the specifics; each is checked against the request: the right patient and dates of service, the record type asked for, the completeness, the signatures and the authentication; the minimum necessary standard is applied and the content outside the request is masked.
Decide
A complete, matched set proceeds by rule; an ambiguous request (dates that match two encounters, a record type the hospital does not keep), a record that cannot be found, a request that exceeds the minimum necessary for its purpose, or an audit sample above the policy's threshold goes to the revenue integrity or health information team in the Decision Desk with the case and only the allowed outcomes (send as assembled, send with an explanation, request clarification from the payer, or escalate to compliance).
Send and write back
The response is sent through the payer's channel (the electronic attachment transaction, the portal upload, or mail) before the deadline, the exact set sent is logged against the claim with the date, the method and the confirmation, and the claim's status is updated in the billing system so the follow-up and the appeal processes have the record.

Where it ends: Every payer request was matched to its case, answered with the specific records checked and masked, sent on the payer's clock, and logged against the claim with what went and when. The Decision Trace shows the match, the record checks and any decision; the Audit Trace shows the request, the chases and the response with time.

Runtime enforcement

What is enforcedwhile the work runs.

The regulations preloaded in Callvu Studio and the bank's own policies, applied as steps that run, not lines in a binder. A step that breaks a rule does not run, so a completed run was compliant.

Regulations

US requirements shown. Ministry of Health runs this process under national rules outside the US; Callvu loads each market's rules as policies the same way.

HIPAA Privacy Rule (45 CFR 164.506 and 164.502(b)): Disclosures to a payer for payment are permitted without authorization, limited to the minimum necessary for the purpose; the hospital must have policies for routine disclosures and review non-routine requests, and the disclosure is tracked where the accounting rules require; the electronic attachment standards govern the transaction where adopted.
Payer documentation and audit rules (the Medicare additional documentation request rules with the 45-day response period, the Medicaid and commercial payer contract terms, the Recovery Audit Contractor rules): Each payer sets the response period for an additional documentation request (45 days for Medicare review contractors, with denial for non-response), the records required by claim type, the audit sampling and extrapolation rules, and the appeal rights that depend on the documentation record; the deadline classification applies the payer's rule.
Medical record authentication and retention (42 CFR 482.24, state record laws): Records sent must be authenticated (signed and dated by the author) and complete; the hospital retains the record and the disclosure log for the state's period, which the appeal and the audit rely on.

Company policies

Every request is matched to the case and classified with its deadline on arrival; nothing sits in a fax queue.
Only the records asked for are sent, checked against the request and limited to the minimum necessary.
Ambiguous requests and unfound records are decided by a person inside the deadline.
The billing system holds the claim's status, and the log of what was sent is the appeal's evidence; the EHR is the record's source.

Controls

Request reading and matching.
Type and deadline classification.
Record pulls from the EHR with department chases.
Checks against the request and minimum necessary masking.
Decision Desk for ambiguity and exceptions.
Channel send before the deadline with logging and claim status update.

Clocks and deadlines

Payer deadline: The payer's response period from the request date (45 days for Medicare review contractors), on the case with escalation before it.
Department chase: Reminders on the schedule inside the deadline.
Claim follow-up: The response date starts the payer's decision period, tracked in the billing system.

The handoff

Between the front doorand the back office.

The front door

The payer's letter, fax, portal or electronic request, read on arrival; departments through their links.

The back office

The revenue integrity and health information teams decide only exceptions; the response and the log run from the case.

The Decision Desk

An ambiguous request, an unfound record, a request beyond the minimum necessary or an audit sample above the threshold goes to the revenue integrity or health information team in the Decision Desk with the case and only send, send with explanation, request clarification, or escalate to compliance.

Questions

What buyers ask next,answered plainly.

How is the request matched?

By reading the payer, the patient identifiers, the dates of service and the claim or authorization reference and matching them to the patient, the encounter and the claim; an ambiguous match goes to a person.

What is sent?

Only the records asked for, pulled from the EHR and the billing system, checked against the request and limited to the minimum necessary, through the payer's channel before the deadline.

Why log what was sent?

Because the appeal and the audit depend on proving exactly what went to the payer and when; the log is on the claim with the method and the confirmation.
