Modifier 57

Modifier 57 is a crucial billing modifier used to indicate the decision for surgery made on the day of or the day before a major procedure. This modifier ensures proper reimbursement for an evaluation and management (E/M) service that directly leads to a surgical procedure.

What is Modifier 57?

Modifier 57 is applied when a provider determines that a major surgical procedure (one with a 90-day global period) is necessary based on an E/M visit. It helps distinguish the decision-making service from the procedure itself, ensuring separate reimbursement.

Uses of Modifier 57

• Applied when an E/M service leads to the decision for major surgery (90-day global period).
• Used to differentiate the E/M visit from the surgical procedure to ensure proper payment.
• Prevents bundling of the E/M service into the surgical global package.

Scenario: Applying Modifier 57

Scenario: A patient visits the emergency department with severe abdominal pain. After evaluation, the physician diagnoses acute appendicitis and decides to perform an emergency appendectomy that same day.

• The correct coding format: 99283-57 (E/M visit leading to surgery) + 44950 (Appendectomy).
• Modifier 57 ensures that the E/M service is separately reimbursed, as it was necessary for determining the need for surgery.
• Without Modifier 57, the payer may bundle the E/M visit into the procedure, resulting in non-payment for the evaluation.

Common Solutions for Correct Billing

1. Ensure the E/M visit is truly for surgical decision-making: Do not use Modifier 57 for routine pre-operative visits.
2. Check the global period: Only apply Modifier 57 if the procedure has a 90-day global period.
3. Provide clear documentation: Medical records should support that the decision for surgery was made during the E/M visit.

Note:

• Modifier 57 is only used for major surgeries (90-day global period), not minor procedures.
• Do not use Modifier 57 on surgical procedure codes—only on the E/M code.
• Incorrect use may lead to claim denials or bundling of E/M services into the procedure payment.
