When to bill the surgical technologist fee?

The surgical technologist fee is an item that raises questions when billing surgical claims: when can it be billed, how is the amount calculated and in which situations does the payer have grounds to deny it? Understanding the CBHPM rules for this professional is the starting point for billing correctly and avoiding losses in the revenue cycle.

What the surgical technologist does

The surgical technologist is a specialized healthcare professional who works directly in the surgical field, assisting the surgeon and the medical team during procedures. Their work covers preparing the operating room, organizing and sterilizing the instruments, providing technical support during surgery, counting materials and sponges and assisting with closing the procedure.

In more complex surgeries, the surgical technologist plays a critical role in the safety and efficiency of the procedure: they anticipate the surgeon’s needs, keep the field sterile and make sure no material is left inside the patient. It is precisely this technical relevance that justifies the possibility of billing separately in certain situations.

When the surgical technologist fee can be billed

The general CBHPM rule is that the surgical technologist’s work is included in the procedure’s operating room fee, that is, it should already be part of the global surgery package. Separate billing depends on what the contract with each payer provides for.

In practice, separate billing tends to be recognized in two main scenarios:

Higher-complexity procedures

In high-tier surgeries (longer, riskier and more technically demanding), the CBHPM allows the surgical technologist fee to be recognized as a separate item. In these cases, the amount is calculated as a percentage of the surgical tier of the main procedure, as detailed in the calculation section below.

Explicit contractual provision

Some payers explicitly provide in their contracts for separate payment of the surgical technologist, even in lower-tier procedures. In these cases, billing follows the criteria defined in the contract itself, which may set value ranges or different percentages. Always check the contract with each payer before adding the item to the claim.

How to calculate the surgical technologist fee

When separate billing applies, the CBHPM establishes that the surgical technologist fee corresponds to 10% of the value of the surgical tier of the main procedure. Since the value of the tier varies according to the procedure’s classification (1A, 5C, 10B and so on), the final surgical technologist amount follows that variation.

The formula is straightforward:

Surgical technologist fee = value of the main procedure’s tier × 10%

The table below shows how the amount varies according to the surgical tier, using as a reference the values of the current CBHPM (October 2025 to September 2026). Tier values in reais should be checked in the current AMB (Brazilian Medical Association) Official Notice:

In small-tier procedures, the 10% result can be a very low amount. In these cases, the contract with the payer commonly sets a negotiated minimum amount. Check whether there is such a provision before billing.

Watch out when billing via the TISS standard

When billing under the TISS standard, the surgical technologist’s fee code must be linked to the main procedure on the form. When this link is not made correctly, the payer’s system cannot calculate the proportionality and denies the item for “incorrect proportionality.”

This error is especially frequent in surgeries with multiple procedures: when there is more than one procedure on the same form, the system applies percentage reductions to the surgical tier of each one. If the surgical technologist’s fee is not associated with the correct procedure, the calculated amount may not reflect the real tier of the main surgery, and the payer has grounds to dispute it.

The most efficient way to prevent this type of denial is to audit the claim before submission, checking that each item is correctly linked and that the percentages applied are consistent with the tier of the main procedure. To understand how to structure this process, see the article on hospital billing management.

Common errors that lead to denials of the surgical technologist fee

Three situations repeat frequently in surgical claims and result in the item being denied:

Billing without a contractual provision

If the payer does not provide for separate payment of the surgical technologist (or if the procedure does not meet the criteria for independent billing), the fee will be denied in full. Always check the contract before adding the item.

Applying the wrong percentage

Billing a fixed amount without applying 10% to the tier of the main procedure is a frequent error, especially when the billing team is not familiar with the rule. The surgical technologist amount must be proportional to the tier, not an arbitrary value.

Not linking the code to the main procedure in TISS

As detailed in the previous section, failing to link correctly under the TISS standard is a common cause of denials for incorrect proportionality. In surgeries with multiple procedures, this error has a larger impact.

Frequently asked questions about the surgical technologist fee

Can the surgical technologist fee always be billed?

No. The general CBHPM rule is that the surgical technologist’s work is included in the operating room fee. Separate billing depends on a contractual provision with the payer or on the procedure falling into the higher-complexity category where the CBHPM allows separate recognition.

How do you calculate the surgical technologist fee under the CBHPM?

The amount corresponds to 10% of the value of the surgical tier of the main procedure. Since the tier varies according to the procedure’s classification in the CBHPM, the surgical technologist amount follows that variation. In small-tier procedures, check whether the contract provides for a minimum amount.

What is a denial for incorrect proportionality?

It is the denial issued when the amount billed for the surgical technologist does not correctly reflect the percentage of the main procedure’s tier. It happens frequently when the surgical technologist’s code is not linked to the correct procedure on the TISS form, especially in surgeries with multiple procedures.

How do you avoid denials when billing for the surgical technologist?

By checking the contract with the payer before adding the item, calculating the amount as 10% of the main procedure’s tier and making sure the code is correctly linked to the procedure on the TISS form. Auditing the claim before submission is the most efficient way to identify inconsistencies.

In surgeries with multiple procedures, how do you bill for the surgical technologist?

The surgical technologist’s fee must be linked to the main procedure of the surgery, which is the one with the highest tier. In surgeries with multiple procedures, the system applies percentage reductions to the tiers of the secondary procedures, and the surgical technologist amount must reflect the tier after these reductions.
