Modifier 25 – Acute Care Services with Preventive Visits

Jun 8, 2026 | Provider News, Provider Resource

Purpose

This billing guide outlines the appropriate use of Modifier 25 when reporting evaluation and management (E/M) services performed on the same date as a preventive medical checkup.

Policy Overview

Providers may be reimbursed for both a preventive checkup and an acute care E/M visit performed on the same date of service when criteria are met, including same provider/group billing, no similar services in prior three years for new patients, and that the acute service is significant and medically necessary.

Modifier 25 Requirements

Modifier 25 must be appended to the E/M procedure code to indicate a distinct, separately identifiable acute care service in addition to the checkup. The service must be supported by a different diagnosis and appropriate level of care.

Documentation Requirements

Medical records must support medical necessity, include a distinct diagnosis beyond preventive codes (Z00.00, Z00.01, Z00.110, Z00.111, Z00.121, Z00.129), reflect the level of E/M service, and include treatment details. Documentation must be retained and available upon request.

Documentation Requirements

Report preventive services with appropriate preventive codes and acute care services with an E/M code appended with Modifier 25. Diagnoses must distinguish services clearly.

Non-Reimbursable Scenarios

Minor or trivial conditions that do not require additional evaluation beyond the preventive visit are not eligible for separate reimbursement and may be subject to recoupment.

Non-Reimbursable Scenarios

If a condition requires further evaluation beyond the preventive visit, a separate E/M service may be billed or the patient may be referred for further care.

Key Takeaway

Modifier 25 should only be used when a significant, medically necessary, and separately identifiable E/M service is performed and properly documented.
