Surgical center management: how to avoid losses and denials

The surgical center concentrates a hospital’s most complex and highest-value operations. It is also where small management failures have disproportionate consequences: a room idle for half an hour, a last-minute cancellation, a poorly documented procedure. Each of these events directly affects billing and opens the door to denials.

What surgical center management is

Surgical center management covers the planning and control of all the resources involved in surgical procedures: teams, rooms, materials, schedule and clinical records. The goal is to ensure that each surgery happens at the right time, with the right resources and with complete documentation for billing.

In practice, this requires coordinating surgeons, anesthesiologists, scrub technicians and support staff, controlling the inventory of surgical materials, managing the cleaning and sterilization interval between procedures and ensuring that every item used is correctly recorded on the patient’s claim.

When any of these steps fails, the impact goes beyond the clinical operation: it reaches the hospital revenue cycle.

How the surgical center affects hospital billing

Surgical procedures have a high average cost and involve multiple billing items: physician fees, anesthesia, consumables, room fees, OPME (orthoses, prostheses and special materials) and inpatient daily rates. Each of these items must be correctly described, coded and documented for the health plan to accept the charge.

When this process fails, the hospital faces two types of financial consequences. The first is technical denials, caused by a TUSS or CBHPM code that does not match the procedure performed. The second is underbilling: items used in surgery and not recorded in the medical record simply never reach the claim. In complex procedures, this can amount to hundreds or thousands of reais per case.

Beyond direct losses, cancellations and rescheduling reduce the department’s productivity and generate fixed costs with no corresponding revenue: scheduled teams, sterilized materials and prepared rooms are an expense even when no surgery takes place.

The main causes of denials and revenue loss in the surgical center

Losses in the surgical center come from three main sources:

• Clinical documentation failures:materials used, procedures performed or complications not recorded in the medical record never reach the claim. The billing specialist charges only for what is documented.

• Incorrect coding: using a TUSS or CBHPM code that does not match the procedure performed leads to a technical denial in the payer’s audit. Surgeries with multiple procedures and OPME use are especially vulnerable to this type of error.

• Cancellations and rescheduling:besides reducing the department’s productivity, cancellations pile up fixed costs with no corresponding revenue and undermine the hospital’s financial predictability.

Indicators to monitor surgical center efficiency

Efficient management starts with measurement. The main indicators to track are:

• Operating room occupancy rate:the percentage of time the rooms are in actual use. Rates below 75% indicate significant idleness and signal an opportunity to gain revenue.

• Surgical cancellation rate:the proportion of surgeries canceled relative to those scheduled. Rates above 5% signal problems with scheduling, preparation or materials availability.

• Average cleaning and preparation time between surgeries (turnover):the longer this interval, the fewer procedures performed in the day.

• Denial rate by type of surgical procedure:makes it possible to identify which surgeries concentrate the most denials and to direct auditing and coding efforts.

• Underbilling rate: the difference between the potential billable amount and the amount actually billed. It requires cross-checking the medical record against the claim.

The role of artificial intelligence in surgical center management

Artificial intelligence works on two critical fronts for the surgical center: operational efficiency and billing integrity.

On the operational side, AI platforms help with intelligent scheduling of rooms and teams, forecasting demand for materials and identifying cancellation patterns before they turn into losses.

On the billing side, AI agents read the clinical records in the medical record, identify the procedures and materials used in surgery and check whether each item was correctly coded and included in the claim. Discrepancies are flagged before submission to the payer, reducing denials and recovering revenue that would go unnoticed in a manual review.

This kind of automated auditing is particularly useful in surgeries with multiple procedures or heavy OPME use, where the volume of billable items is high and the risk of loss from underbilling is proportionally greater.

Surgical center management defines the hospital’s financial health

A well-managed surgical center generates predictable revenue, reduces denials and sustains the hospital’s financial margin. The difference between this scenario and its opposite lies in the quality of the information available and the ability to act on it in real time.

Technology, well-defined processes and integration between clinical operations and billing are the pillars of this transformation. Many hospitals already use artificial intelligence platforms to automate the revenue cycle, reduce denials and ensure that every surgical procedure is correctly billed.

Rivio uses AI to manage this entire cycle, from audit to payment, allowing hospital teams to focus on patient care while technology takes care of the financial integrity of the operation.
