Hospital claim denials: how to measure, prevent and recover
A denial is revenue the hospital produced and did not receive. Measuring it well is the first step to recovering what is undue and stopping it from recurring.
Hospital claim denials ("glosas" in Brazil) are full or partial refusals by a health plan or SUS to pay items on the patient account. Each denial is revenue the hospital already produced, with cost already incurred, that may not be collected. That is why denial management has three fronts: measure, prevent and recover.
Types of denial
| Type | What it is | Examples |
|---|---|---|
| Administrative | Process or documentation failure | Missing authorization, incomplete claim form, registration error, late submission, incompatible code |
| Technical | Clinical questioning of what was done | Procedure without justification in the medical record, supplies above expected quantity, questioned daily rate |
| Linear | Cut applied without item-by-item analysis | A percentage deducted from every account in a batch |
It is also important to separate the initial denial, reported by the payer and open to appeal, from the final denial, after appeals are exhausted.
How to measure
The basic indicator is the denial rate: denied amount ÷ billed amount. But the hospital-wide number says little. Break it down by:
- Payer: a few concentrate most of the value.
- Reason: administrative and technical denials have different solutions.
- Department and item type: daily rates, supplies, drugs, implants, physician fees.
- Stage: initial denial, amount appealed, amount recovered, final denial.
With this breakdown, the Pareto rule usually appears: a few payers and reasons explain most of the value. That is where action starts.
How to prevent
The best denial is the one that never happens. The most effective practices act before submission:
- Authorization secured before the procedure, with the correct form.
- Pre-billing: checking the account before submission (documentation, coding, quantities, compatibility).
- Up-to-date tables: each payer's prices and rules registered correctly in the system.
- Complete medical records: justifications recorded for what was done, especially supplies and daily rates.
- Deadlines: submission within each payer's contractual deadline.
- Feedback to the source: each recurring denial reason becomes training for the department that caused it.
How to recover
Not every denial is due. Appeals require organization:
- Group denials by payer and reason and prioritize by value.
- Respect each contract's appeal deadlines.
- Attach the documentation proving what was done.
- Track the outcome: how much was appealed, how much was recovered and how long it took.
The TISS standard, set by ANS (Brazil's health plan regulator), defines the electronic exchange of information between providers and health plans, including denial returns, which makes tracking easier when the hospital uses the fields correctly.
Denials in the result and in cash
Denials reduce revenue and therefore each payer's contribution margin. They also delay cash: until the appeal is decided, the amount stays pending. That is why denials should be read together with the average collection period and unbilled accounts. For hospitals running Tasy, see billing and denials.
Related questions
What denial rate is acceptable?
It varies widely by hospital profile, payer and type of care. Rather than looking for a market benchmark, track the hospital's own trend and the rate by payer and reason.
Are denials and defaults the same thing?
No. A denial is a refusal to pay an item; a default is a delay or non-payment of an accepted amount.
Who should be responsible for denials?
Billing coordinates, but prevention depends on the departments that build the account: admissions, authorization, nursing, pharmacy and the medical staff.
