• UHC’s new GA modifier requirement: what you need to know

    Effective Feb. 1, UnitedHealthcare (UHC) will require physician practices to append the GA modifier to commercial plan claims for services they know or suspect are not covered. UHC says this change will enhance health care transparency by ensuring patients are informed of potential out-of-pocket costs in advance.

    Understanding the GA modifier requirement

    The GA modifier indicates that a practice has obtained a patient's written consent acknowledging their financial responsibility for a non-covered service. Failure to secure consent and indicate it using the modifier will prohibit practices from billing the patient for the service.

    Action steps

    To comply with this new requirement:

    1. Educate staff: Ensure clinical and administrative staff are aware of the requirement and implement a process to ensure compliance.

    2. Assess coverage: Determine if the service is covered under the member's benefits.

    3. Obtain consent: If the service is likely not covered, secure written consent from the patient. Generic, blanket, or blank consent forms are not allowed. The consent must include:

    • An estimate of the charges for that service,
    • A statement explaining the reasons you believe the service may not be covered,
    • If UHC has determined the planned services are not covered (i.e., a practice has submitted a prior authorization or benefits check and UHC responded by stating the services were not covered), a statement that the patient knows UHC has determined the services aren’t covered and the patient agrees to be responsible for the charges.

    4. Maintain records: Keep a copy of the consent in the patient medical record.

    5. Use the GA modifier: Include the GA modifier on the claim to indicate that you obtained proper consent.

    Additional Information

    More details are available in UHC's 2025 Administrative Guide for Commercial Plans. For further assistance, practices can access 24/7 support through the UHC’s Provider Portal.
