Mastering Telehealth Billing: POS and Modifier Checks for Behavioral-Health Claims

Telehealth has transformed how behavioral health services are delivered, offering accessibility and continuity of care for many New Mexicans. For providers and their billing teams, this shift requires a thorough understanding of specific billing requirements, particularly regarding Place of Service (POS) codes and appropriate modifiers. New Mexico Billing supports behavioral health providers in navigating these evolving guidelines to ensure claims are submitted accurately and efficiently.

The flexibility of telehealth services means that care can be provided from various locations, impacting the billing process. Payer policies dictate which POS codes and modifiers are valid under different circumstances. Staying current with these policies is key to avoiding claim rejections and ensuring smooth revenue cycle management for services like psychotherapy (e.g., 90832, 90834, 90837), crisis intervention (e.g., 90839, 90840), family therapy (e.g., 90846, 90847), and group psychotherapy (90853).

Place of Service (POS) codes indicate where a service was rendered. For telehealth, specific codes are designated to reflect that the service was provided remotely, differentiating it from in-person care. These codes are critical because they inform the payer about the nature of the service delivery and often influence reimbursement. Selecting the correct POS code is a fundamental step in compliant telehealth billing.

In New Mexico, for services supported by New Mexico Medicaid and various managed care organizations (MCOs), the most commonly used POS code for telehealth behavioral health services is POS 02. This code signifies that the service was provided via telehealth from a location other than the patient’s home. However, it is essential to verify the specific requirements of each payer, as some may have adopted or experimented with other codes, such as POS 10, which indicates a service provided via telehealth in the patient's home. Always check the applicable MCO provider manual or New Mexico Medicaid Behavioral Health Policy and Billing Manual for the most current and specific guidance.

Incorrect POS codes are a common reason for claim denials. Even if the service was appropriately delivered via telehealth, an error in the POS code can lead to delays in payment. New Mexico Billing assists providers in establishing workflows to verify the correct POS code for each service, date of service, and payer, reducing these common billing errors.

Modifiers provide additional information about a service without changing the meaning of the CPT or HCPCS code itself. For telehealth services, specific modifiers are often required to indicate that the service was delivered remotely, clarify the modality, or specify certain conditions under which the service was provided. These modifiers work in conjunction with the POS code to paint a complete picture for the payer.

The most widely recognized modifier for professional services furnished via telehealth is modifier 95. This modifier is appended to the CPT code (e.g., 90834-95) to indicate that the service was provided via real-time interactive audio and video telecommunications system. Many payers, including New Mexico Medicaid and various MCOs, expect to see modifier 95 when billing for telehealth services that meet their interactive audio-video criteria. Some payers may also accept or require a modifier GT, especially for older policies, though 95 has become more prevalent.

Another modifier, FQ, has been associated with services furnished via audio-only communications. While many policies initially focused on interactive audio-video, there has been increasing recognition of the need for audio-only services, particularly in certain circumstances or for specific populations. However, the acceptance and requirements for audio-only telehealth billing with modifiers like FQ can vary significantly by payer and may be subject to temporary waivers or specific policy updates. Providers should carefully consult payer-specific guidance to confirm the use of any audio-only telehealth modifiers.

New Mexico Billing understands the complexities of modifier application and supports providers in implementing accurate modifier workflows. This includes distinguishing between scenarios requiring audio-video modifiers, audio-only modifiers, or other modifiers that might apply concurrently, such as those indicating professional services or assistant surgeons, depending on the service and policy.

Submitting a claim with the correct POS code and modifier is only one part of compliant telehealth billing; robust documentation is equally critical. Payer policies often require detailed clinical documentation to support that the telehealth service met the criteria for remote delivery and was medically necessary, aligning with the client's diagnosis and treatment plan.

Documentation for telehealth services should clearly state that the service was rendered via telehealth, specify the modality (e.g., video conference, audio-only), and note the locations of both the client and the rendering provider. It should also describe any technology used and confirm the client's informed consent for telehealth services. The CPT code description, duration (e.g., for 90832, 90834, 90837), and content of the session must be reflected accurately in the notes, just as they would be for an in-person service.

Without proper documentation, even correctly coded claims can face denials during audits. New Mexico Billing helps behavioral health providers understand the documentation expectations for various services and payers, including for IOP services delivered via telehealth, ensuring that the clinical record supports the billing submitted. This holistic approach to claim preparation is vital for successful revenue cycle management.

New Mexico Medicaid (Turquoise Care) and its contracted Managed Care Organizations (MCOs) – Blue Cross and Blue Shield of New Mexico (BCBSNM), Molina Healthcare of New Mexico, Presbyterian Health Plan, and UnitedHealthcare Community Plan – each have their own provider manuals and billing guidelines, which can include specific nuances for telehealth. While there's often broad alignment, differences in accepted POS codes, required modifiers, and documentation standards can exist.

Providers should routinely check for updates from each payer. For example, some MCOs might have specific limitations on audio-only services or requirements for specific telehealth platforms. Enrollment and credentialing with each MCO, often supported by processes involving YES.NM for roster submissions, are foundational for billing any services, including telehealth. Additionally, services like IOP delivered via telehealth require adherence to specific program guidelines and often prior authorization, which must be secured before services are rendered.

New Mexico Billing specializes in supporting workflows involving these specific New Mexico payers. We are familiar with MCO credentialing processes, YES.NM enrollment workflows, and the common requirements for behavioral health services, including those delivered remotely. This expertise helps providers navigate the complex landscape of New Mexico behavioral health billing for telehealth.

Despite the clear benefits of telehealth, billing for these services can present several challenges. Common pitfalls include using incorrect POS codes, omitting required modifiers, failing to update policies as payer rules change, and insufficient documentation. These errors frequently lead to claim denials, necessitating time-consuming appeals and re-submissions.

To mitigate these issues, behavioral health providers should establish a robust internal review process for all telehealth claims. This process should include verifying the client's eligibility and benefits, securing any necessary prior authorizations, and confirming the correct CPT code, POS code, and modifiers for each service. Regular training for billing staff on payer-specific updates is also invaluable.
