The impact of denials on the hospital revenue cycle

Denials are one of the biggest pressures on the operating margin of hospitals, clinics and diagnostic centers. However, the impact of a procedure denied by a payer goes beyond the immediate loss of revenue: it sets off a domino effect that undermines the revenue cycle as a whole.

With rising care costs and increasingly squeezed margins, the denial is no longer an acceptable cost; it has become a strategic survival challenge. Understanding its causes and effects is essential to ensure predictable cash flow and administrative efficiency.

What are denials and why do they destabilize the revenue cycle?

A denial is the cancellation or refusal of payment of healthcare service bills by payers. Denials occur when there is a discrepancy between the care provided, the documentary record and the contractual or regulatory rules (such as the TISS standard).

Denials hurt three vital pillars:

1. Financial liquidity: they reduce net revenue and cause critical delays in cash inflows.

2. Operational efficiency: they require a high volume of rework (denial appeals), burdening audit and billing teams.

3. Opportunity cost: capital tied up in denials is not reinvested in technology and care improvements.

Critical stages: at what point is revenue harmed?

Denials do not arise in billing; they are the result of failures accumulated along the patient journey:

• Registration and eligibility: errors in checking waiting periods or missing prior authorizations account for about 30% to 40% of administrative denials.

• Recording and care: this is where the “technical denial” occurs. Incomplete medical records, missing nursing check-offs or the absence of clinical justifications prevent the payer from validating payment.

• Coding and audit: coding failures (TUSS/CBHPM) and the lack of robust prospective audit allow basic errors to reach the payer, lengthening the payment cycle.

Financial impact in numbers and indicators

The losses caused by denials are directly reflected in the institution’s planning:

• Higher DSO (Days Sales Outstanding): the average time to payment soars, hurting working capital.

• Revenue erosion: the administrative cost of recovering a denial can often exceed the value of the claim itself, reducing real profit.

• Low recovery rate: historically, technical denials are harder to reverse, resulting in permanent losses (bad debt).

The Brazilian healthcare sector faces constant updates to guidelines from the National Supplementary Health Agency (ANS) and changes to the list of covered procedures. In addition, payers apply increasingly strict compliance rules. Without technological standardization, therefore, human error becomes almost inevitable.

Why doesn’t the reactive model work anymore?

Many institutions focus their efforts on the denial appeal. Although necessary, it is a remedy for the symptom, not a cure for the disease. Acting only on appeals means accepting the cost of rework and the risk of a final denial.

The turning point lies in preventive management: identifying the error before the claim leaves the hospital. Some of the most important prevention strategies are:

1. Concurrent audit: monitoring the claim while the patient is still admitted, correcting recording failures in real time.

2. Data integration: unifying the clinical and administrative views to ensure that what was prescribed was actually charged.

3. Root cause analysis: using data intelligence to identify which payers or procedures generate the most denials and why.

4. Team training: reinforcing with the medical staff the importance of proper recording for the institution’s sustainability.

The Rivio view

At Rivio, we turn the fight against claim denials into a competitive advantage. Using advanced algorithms, our solutions analyze historical denial patterns and identify denial risks predictively.

Rivio’s AI platform handles the entire hospital revenue cycle, increasing revenue and operational efficiency. From audit to payment, our technology analyzes clinical records, cross-checks the information against hospital claims, identifies and corrects denials, submits the XML and manages appeals, all automatically.
