Hospital billing checklist: what to check and submit

A well-applied hospital billing checklist is one of the simplest and most underrated tools for reducing denials at the source. While much of billing teams’ effort goes into appealing what the payer has rejected, systematic review before submission acts exactly where the cost is lowest: before the error leaves the hospital.

In 2024, the initial denial rate of Brazilian private hospitals reached 15.89%, according to the Anahp Observatory 2025 (National Association of Private Hospitals). A significant share of that volume originates in operational failures that a structured pre-submission review can intercept: a code that does not match the procedure performed, an authorization that had expired on the date of care, a report left pending, an item billed twice. Caught before submission, they are fixed in minutes. Caught afterward, they become denials, appeals and rework.

This article presents the five blocks of the checklist, with the items to check in each one.

Why pre-submission review is the last line of defense

Once the claim leaves the hospital, control passes to the payer. The payer reviews it, denies whatever it considers incorrect and sends back a notification that the hospital has to process, appeal and follow up on. Each stage of this cycle has a cost: the team’s time, a longer time to payment and, in cases without reversal, a permanent loss of revenue.

Pre-submission review acts before that. The hospital identifies the error while it is still inside the internal process, corrects it and sends a claim that is ready to be paid. No denial, no appeal, no rework.

The average time to payment for hospitals that are members of Anahp was 68.56 days in 2024. A significant part of that time reflects claims held up by inconsistencies that preventive auditing would have intercepted.

Every claim submitted correctly is one day less in that time and one more amount available in cash. The cost of these errors goes beyond the amount denied: it includes rework, extended payment times and permanent losses in cases without reversal.

A checklist in verification blocks

The pre-submission checklist covers five verification blocks, each responsible for a specific type of error that leads to denials. Together, they are the last opportunity to make corrections before the cost of the error multiplies.

Block 1: registration data and eligibility

Registration errors are the most silent in billing: they go unnoticed at admission, run through the entire episode of care and only show up as a denial when the payer spots the inconsistency. A wrong digit in the member ID number or a name that differs from the payer’s records can be fixed in seconds at admission and becomes a complex problem weeks later.

Before submitting, check that:

• The patient’s name matches the ID document and the payer’s records.

• The member ID number is valid and active on the date of care.

• The plan covers the type of care provided: elective, urgent or inpatient.

• The plan member is the registered and identified primary holder or dependent.

Block 2: authorization and coverage

Missing prior authorization for elective procedures is one of the errors with the highest unit cost in hospital billing: it results in a full denial of the episode of care, with low reversibility. In urgent and emergency cases, ANS (Brazil’s National Supplementary Health Agency) regulations allow care to begin without prior authorization, but require regularization with the payer within 24 hours, according to contractual rules and industry regulations.

See the main reasons for health plan denials to understand how each type of authorization failure affects billing.

Before submitting, check that:

• The authorization number was obtained before the elective procedure.

• The authorization number is valid on the date the procedure is performed.

• Urgent and emergency care was regularized with the payer within the deadline.

• Complications during the hospital stay that require additional authorization are recorded and authorized.

Block 3: coding and items billed

Coding errors are the most frequent and, at the same time, the most avoidable. An incorrect TUSS code, a quantity billed above what was authorized, a duplicate item in the batch, an outdated price table for that payer: each leads to a denial for a specific reason, but they all have the same origin.

See the five most common errors in hospital billing to understand the patterns that repeat most often.

Before submitting, check that:

• The TUSS code matches the procedure actually performed.

• The quantities billed match what was authorized and what is recorded in the medical record.

• Materials and medications have the correct code and quantity.

• There are no duplicate items in the batch.

• The price table applied is the current one for that payer.

Block 4: clinical documentation

Clinical documentation is what supports the charge. When it is incomplete, the payer has no way to validate that the procedure was necessary, appropriate and actually performed. The result is a denial for a documentation failure, which is highly reversible but takes time and rework to resolve. Most documentation problems originate before billing, in the clinical record made during care.

Before submitting, check that:

• The medical report is present and signed when required by the procedure or by the payer.

• The medical record contains a complete record of care: progress notes, prescriptions and discharge.

• The recorded diagnosis is consistent with the procedures billed.

• The OPME (implants and special materials) report identifies the material, manufacturer, serial number and invoice, when applicable.

Block 5: contract compliance

Each payer has its own rules that override the TISS standard. Items covered in one contract may be out of scope in another. Fee tables have different versions for each health plan. Submission deadlines vary. When the billing team is not clear on the specific rules of each contract, compliance errors pile up silently. It is revenue that leaves without anyone noticing right away.

Before submitting, check that:

• The items billed are within the scope of the contract with that payer.

• The fee and materials table is up to date for that payer.

• The contractual deadline for submitting the batch is being met.

• The forms are filled in according to the current TISS standard.

A checklist only works if it becomes routine

A checklist applied once is a good intention. Applied before every submission, by any member of the team, regardless of the day’s volume, it is a process. That difference separates billing that progressively reduces denials from billing that lives with the same errors every month.

The practical challenge is that the volume of claims a hospital processes makes manual review unfeasible at scale. A small team under deadline pressure tends to prioritize submission speed over review quality. The errors that slip through are exactly the ones the checklist existed to catch.

Rivio automates this review. The platform audits 100% of claims before submission, cross-checking clinical and administrative data to identify inconsistencies in the five blocks the checklist covers: registration, authorization, coding, documentation and contract compliance. With a contractual commitment to full reimbursement for any denial that is not reversed, Rivio turns pre-submission review from a task that depends on discipline into a process guarantee.

Frequently asked questions about hospital billing checklists

What is a hospital billing checklist?

It is a structured verification list that the billing team applies before sending claims to payers. Organized into thematic blocks, it covers the main points of failure that lead to denials: registration data, authorization, coding, clinical documentation and contract compliance. Its goal is to identify and correct inconsistencies before the claim leaves the hospital.

What are the most common errors the checklist prevents?

The most frequent are: an expired or missing authorization number, an incorrect TUSS code for the procedure performed, an item billed twice, a missing or unsigned medical report and billing for an item outside the payer’s contractual scope. Each of these errors has a specific block in the checklist.

How often should the checklist be applied?

Before every batch submission to the payer. How often batches are sent varies by contract and by payer, but the review should always happen, regardless of volume. Applying the checklist only to large batches or when in doubt reduces its value: the costliest errors tend to be the ones that go unnoticed in the routine.

How can pre-submission claim review be automated?

Automating pre-submission review depends on a system that automatically cross-checks clinical and administrative data, flagging inconsistencies before the batch is closed. That requires integration between the electronic medical record, the billing system and the audit platform. With that integration, the auditable volume is determined by the institution’s flow of claims.
