Family Therapy Billing Workflow: Navigating CPT Codes 90846 and 90847 in New Mexico

In the landscape of behavioral health services, family therapy plays a vital role in addressing relational dynamics and supporting overall well-being. For billing purposes, two primary Current Procedural Terminology (CPT) codes are used to describe these services: 90846 and 90847. These codes distinguish between sessions conducted with or without the patient present, which is a critical detail for accurate claim submission and compliant documentation.

CPT code 90846 is typically used for family psychotherapy sessions where the identified patient is *not* present. This code acknowledges that therapeutic work with family members can be beneficial even when the primary patient is not directly participating in the session. It focuses on the family's dynamics and how they impact the patient's treatment and recovery. Conversely, CPT code 90847 describes family psychotherapy sessions where the identified patient *is* present, indicating direct engagement with the patient and their family unit in the therapeutic process.

Understanding this distinction is paramount for New Mexico behavioral health providers. Each code carries specific documentation requirements and may have unique payer policies regarding coverage, duration, and frequency. Providers should always confirm the exact descriptors and time requirements for these codes in the current AMA CPT codebook and consult applicable payer-specific policies, such as those issued by New Mexico Medicaid or various Managed Care Organizations (MCOs).

Thorough and accurate documentation is the bedrock of successful behavioral health billing, and family therapy is no exception. For both 90846 and 90847, the clinical record must clearly justify the medical necessity of the service and differentiate it from individual or group therapy. This includes detailing the therapeutic intent, the specific family members present (including their relationship to the identified patient), and the focus of the session.

Documentation for family therapy should clearly link the intervention to the patient's treatment plan goals. It's essential to describe how addressing family dynamics contributes to the patient's progress and recovery. For CPT 90846, where the patient is absent, the note should explain why the session was conducted without the patient and how the family members' participation directly impacts the patient's care. For 90847, with the patient present, the documentation should reflect the interaction and engagement of all participants.

Beyond the basic elements, the documentation should also include the date of service, start and end times to establish duration, the type of service (family psychotherapy), the CPT code billed, and the rendering provider's signature and credentials. Payers may also look for evidence of specific interventions used, progress towards goals, and the plan for future sessions. Maintaining detailed, contemporaneous notes is crucial for supporting claims and navigating potential audits or reviews.

Before providing family therapy services, New Mexico behavioral health providers must proactively verify patient eligibility and secure any necessary authorizations, especially for Medicaid and MCO plans. While New Mexico Medicaid and its MCOs (such as Blue Cross Blue Shield of New Mexico, Molina Healthcare of New Mexico, Presbyterian Health Plan, and UnitedHealthcare Community Plan) generally support family therapy, specific requirements for authorization can vary significantly between plans and even based on the patient's specific benefit package.

Providers should never assume that an authorization for individual therapy automatically extends to family therapy. Some MCOs may require a separate authorization for CPT codes 90846 and 90847, particularly if it's the first time these services are being rendered or if certain frequency thresholds are met. It's critical to review the applicable MCO provider manual or contact the payer directly to understand their specific authorization guidelines, including the criteria for medical necessity and the required documentation for approval.

Eligibility checks should be performed at each visit to confirm active coverage and benefits. This helps prevent claims denials due to lapses in coverage or changes in the patient's plan. Understanding payer-specific rules for authorization and eligibility is a cornerstone of effective revenue cycle management and ensures that providers are appropriately reimbursed for the valuable family therapy services they provide to New Mexico communities.

Billing for family therapy, like other psychotherapy services, involves careful consideration of units and the appropriate Place of Service (POS) code. Both CPT 90846 and 90847 are typically billed as one unit per session, regardless of the number of family members present. The duration of the session, as documented, should align with the typical timeframes associated with these codes, which providers should confirm against the current AMA CPT codebook and payer-specific policies.

The Place of Service (POS) code is a two-digit code that indicates where the service was rendered. For in-person family therapy conducted in an office setting, POS code '11' is commonly used. However, with the expanded use of telehealth, providers may also render family therapy via synchronous audio and video technology. When providing telehealth services, the appropriate telehealth POS code should be used, often '02' for synchronous telecommunication services provided other than in a patient's home, or '10' for synchronous telecommunication services provided in the patient's home. It is crucial to verify the current POS codes and modifier requirements for telehealth services with each specific MCO and New Mexico Medicaid, as these can be updated.

Accurately selecting the POS code is vital for proper claim processing. An incorrect POS code can lead to denials, necessitating time-consuming corrections and resubmissions. Providers must stay informed about current guidelines for both in-person and telehealth services to ensure compliance and maximize reimbursement accuracy.

The diagnosis codes submitted with family therapy claims must accurately reflect the patient's condition and demonstrate medical necessity for the family intervention. For CPT codes 90846 and 90847, the primary diagnosis code billed should typically be for the identified patient, even if the therapy focuses on family dynamics. The selected diagnosis should align directly with the issues being addressed in therapy and be supported by the clinical documentation.

The treatment plan is a critical component that links the patient's diagnosis to the family therapy interventions. It should clearly articulate how working with the family unit (with or without the patient present) contributes to achieving the patient's overall treatment goals. This plan should be reviewed and updated regularly to reflect changes in the patient's condition and the family's progress. Payers look for a clear connection between the diagnosis, the treatment plan's objectives, and the services rendered.

In cases where family therapy addresses relational issues that may not directly map to the identified patient's primary mental health diagnosis (e.g., V-codes or Z-codes for relational problems), providers should verify with the specific MCO whether these diagnosis codes are considered reimbursable for family therapy. Some payers may require a mental health diagnosis for the identified patient as the primary code, with relational issues as secondary diagnoses. Careful coding and detailed documentation are essential to justify the service.

Even with careful attention to detail, claims for family therapy services may sometimes be denied or partially paid. Understanding how to interpret Electronic Remittance Advice (ERA) and effectively manage denials is a critical skill for New Mexico behavioral health practices. Common reasons for denials related to CPT 90846 and 90847 can include lack of authorization, incorrect POS code, insufficient documentation of medical necessity, or issues with patient eligibility.

When an ERA arrives indicating a denial, the first step is to carefully review the denial code and explanation provided. This code will usually offer a clue as to why the claim was rejected. Providers should then cross-reference this information with their clinical documentation, the patient's eligibility records, and the authorization status. If the denial is due to a correctable error, such as a missing modifier or incorrect POS code, the claim can often be corrected and resubmitted promptly.

For more complex denials, such as those related to medical necessity or authorization issues, an appeal may be necessary. This typically involves submitting a written appeal with additional supporting documentation, such as detailed progress notes, the treatment plan, and any authorization numbers. Effective denial management is an ongoing process that requires diligent tracking, understanding payer-specific appeal processes, and continuous improvement of internal billing workflows to minimize future denials.

The use of telehealth has become an integral part of behavioral health service delivery, extending to family therapy sessions (90846 and 90847). New Mexico Medicaid and its MCOs have generally adopted policies to support telehealth for these services, but specific requirements can vary. Providers must ensure they are using appropriate technology that meets HIPAA compliance standards for secure audio-video communication.

When billing for telehealth family therapy, it's essential to use the correct Place of Service (POS) code, such as '02' (Telehealth Provided Other Than in Patient’s Home) or '10' (Telehealth Provided in Patient’s Home), depending on where the patient is located. Additionally, some payers may require specific modifiers, such as '95' (Synchronous Telemedicine Service Rendered Via a Real-Time Interactive Audio and Video Telecommunications System) or 'GT' (Via interactive audio and video telecommunication systems) to indicate that the service was provided via telehealth. It is imperative to consult the most current guidelines from New Mexico Medicaid and each MCO, as telehealth policies can be dynamic and subject to change.

Documentation for telehealth family therapy sessions should mirror in-person sessions, with additional notes specifying that the service was rendered via telehealth, identifying the platform used, and confirming the presence of all participants via the virtual connection. Verifying the patient's location at the time of service is also often required. Staying updated on payer-specific telehealth policies is crucial for accurate billing and avoiding denials.

Navigating the intricacies of family therapy billing for CPT codes 90846 and 90847 in New Mexico requires ongoing diligence and a commitment to accurate processes. For New Mexico behavioral health providers, robust revenue cycle support can be invaluable. This includes establishing clear internal workflows for eligibility and authorization checks, ensuring meticulous documentation practices, and staying updated on payer-specific policies.

Regularly training your team on billing updates, especially for New Mexico Medicaid and MCOs like Blue Cross Blue Shield of New Mexico, Molina, Presbyterian, and UnitedHealthcare, can significantly reduce denials. Consider conducting periodic internal audits of your claims and documentation for family therapy to identify areas for improvement before they impact your revenue cycle. Proactive engagement with these billing complexities allows you to focus more on delivering essential family therapy services to those who need them.

By focusing on these practical steps and leveraging comprehensive billing support, your practice can achieve greater efficiency and accuracy in billing for family therapy, supporting the overall financial health of your organization and ensuring continued access to care for New Mexico families.
