99484: billing BHI without a psychiatric consultant

Summary

99484 pays for general behavioral health integration — a monthly service built around a systematic assessment and monitoring process using a validated rating tool, plus a care plan, delivered by or under the billing practitioner's clinical staff. Unlike the collaborative care codes, it does not require a psychiatric consultant relationship, which is what makes it realistic for a solo primary care or behavioral health practice without a formal psychiatry contract already in place.

How do I bill general behavioral health integration, 99484?

99484 pays for a calendar-month of general behavioral health integration: ongoing assessment and monitoring of a patient's behavioral health condition using a validated rating tool, a behavioral health care plan, and care coordination, delivered by the billing practitioner or clinical staff acting under them. Medicare's BHI billing guide describes the required care-team elements and the validated-rating-scale expectation shared across the BHI and collaborative care code family 1Ref 1Centers for Medicare & Medicaid Services (2024).Behavioral Health Integration Services.That Medicare pays for general behavioral health integration and collaborative care management (99484, 99492-99494, G2214) and describes the required care-team elements and validated-rating-scale use, used here to explain 99484's monthly assessment, care-plan, and documentation requirements and how the care team is structured under the billing practitioner..

What makes 99484 different from the collaborative care codes it sits next to is that it does not require a psychiatric consultant relationship — no formal arrangement with a psychiatrist reviewing a registry of cases. That single difference is why 99484 is the more realistic entry point for a solo practice that wants to bill for integrated behavioral health work without first building a collaborative-care structure.

Who does the work, and who bills it

99484 is billed by the treating practitioner — a physician or other qualified health professional managing the patient's care — and the monthly monitoring and coordination work is typically carried out by clinical staff acting under that practitioner's direction, the same incident-to in behavioral health arrangement that governs other staff-delivered behavioral health services. The care-team structure and what has to be documented to support it are laid out in Medicare's BHI guidance 1Ref 1Centers for Medicare & Medicaid Services (2024).Behavioral Health Integration Services.That Medicare pays for general behavioral health integration and collaborative care management (99484, 99492-99494, G2214) and describes the required care-team elements and validated-rating-scale use, used here to explain 99484's monthly assessment, care-plan, and documentation requirements and how the care team is structured under the billing practitioner..

For a solo practice, this usually means a nurse, medical assistant, or behavioral health-trained staff member does the recurring monitoring calls and check-ins, while the billing practitioner remains the one accountable for the plan of care and available for the oversight the arrangement requires.

What has to happen — and be documented — each month

To bill a full month of 99484, the record needs to show ongoing assessment and monitoring using a validated behavioral health rating tool, a behavioral health care plan that gets revised as the patient's status changes, and continuity — the same care team following the same patient month over month rather than a series of disconnected contacts 1Ref 1Centers for Medicare & Medicaid Services (2024).Behavioral Health Integration Services.That Medicare pays for general behavioral health integration and collaborative care management (99484, 99492-99494, G2214) and describes the required care-team elements and validated-rating-scale use, used here to explain 99484's monthly assessment, care-plan, and documentation requirements and how the care team is structured under the billing practitioner.. Systematic monitoring means a repeatable process, not a single conversation logged once and left unchanged for months.

The note that ties a given month's contacts back to the care plan and the validated tool's score is what a reviewer looks for — the golden thread connecting the assessment, the plan, and the billed time is what turns a set of check-in calls into a service Medicare recognizes as BHI rather than informal follow-up.

Where it's delivered: office, telehealth, or by phone

BHI's monthly contacts commonly happen by phone or secure video rather than in the office, and the place-of-service code on the claim has to reflect where the service happened — office (11), the patient's home (10), or a telehealth setting (02) are each defined in CMS's POS code set, and each can affect facility-versus-non-facility payment 2Ref 2Centers for Medicare & Medicaid Services (2026).Place of Service Code Set.That the POS code set — office 11, home 10, telehealth 02, among others — is defined by CMS and determines facility-versus-non-facility payment, used here to explain choosing the correct POS code for a BHI contact delivered by phone, video, or in office.. Getting the POS code wrong is a quieter error than an outright coding mistake, but it still misstates where and how the service was delivered.

Because BHI is built around recurring, often non-face-to-face contact, a solo practice's workflow benefits from deciding upfront which staff member owns the monthly calendar of contacts and which POS code applies to each contact type, rather than reconstructing that after the fact when the claim is being prepared.

Coordinating with a patient's other behavioral health care

A patient receiving BHI from their practice may also be in concurrent bh care with a separate therapist, and the two clinicians are typically coordinating different pieces of the same treatment rather than duplicating each other's work. Keeping that coordination visible in the record — who is doing what, and that the BHI plan reflects the other treatment — protects against a reviewer reading two claims as overlapping.

How the visit's diagnosis coding, including the z-codes that document the psychosocial and situational context behind a behavioral health condition, supports the medical necessity picture is its own topic worth reading before billing at volume, since a diagnosis list that only names the clinical condition and skips the context around it tells a thinner story than the note actually contains.

Who is eligible to bill 99484

The BHI codes sit within Medicare's broader mental health coverage, which — since medicare's 2024 opening of Part B billing to marriage and family therapists and mental health counselors — now recognizes more provider types for behavioral health services than it once did 3Ref 3Centers for Medicare & Medicaid Services (2025).Medicare and Mental Health Coverage.That Medicare's mental health coverage booklet lists eligible provider types for behavioral health billing, including marriage and family therapists and mental health counselors since 2024, used here to explain who is eligible to bill 99484. As of July 2026.. Whether a specific solo practice's billing practitioner qualifies to bill 99484 depends on that provider-type eligibility, not on specialty alone, so confirming eligibility against the current guidance beats assuming it from a prior year's rules.

This is also why the mix of psychotherapy, general BHI, and collaborative care codes available to a given solo practice looks different depending on whether the billing practitioner is a physician, an NP or PA, or one of the newly eligible behavioral health specialties — the eligible code list is not identical across all of them.

Checking coverage and what 99484 pays

Whether a jurisdiction has published any coverage article specific to behavioral health integration is worth checking in the Medicare Coverage Database before building a monthly workflow around assumptions carried over from a different state or a different MAC 4Ref 4Centers for Medicare & Medicaid Services (2026).Medicare Coverage Database (MCD) Search.That national coverage decisions and MAC-specific coverage articles are searchable in the public Medicare Coverage Database, used here as the lookup method for any jurisdiction-specific BHI coverage guidance.. Coverage details that vary regionally are exactly the kind of thing worth confirming once, in writing, rather than discovering through a batch of denials.

What 99484 actually pays — like any code — is not a number worth memorizing, since CMS's Physician Fee Schedule Search tool shows the current national and locality-adjusted amount and updates with each year's rulemaking 5Ref 5Centers for Medicare & Medicaid Services (2026).Physician Fee Schedule Search.That CMS publishes a public Physician Fee Schedule look-up tool showing the current, annually updated national and locality payment amount and RVUs for any code, used here as the method for checking what 99484 currently pays in the reader's locality.. For a service built around recurring monthly staff time, knowing the real payment rate for your locality is what determines whether the workflow is worth the staff hours it requires.

Common questions

No. That's the key difference between 99484 and the collaborative care management codes, 99492-99494, which require a formal psychiatric consultant relationship. 99484 needs a validated rating tool, a behavioral health care plan, and ongoing monitoring by the billing practitioner's care team, but not a psychiatrist reviewing a case registry.

The treating practitioner managing the patient's care — a physician or other qualified health professional whose provider type is eligible under Medicare's current behavioral health coverage rules, which since 2024 include marriage and family therapists and mental health counselors alongside the provider types that could already bill it.

A validated behavioral health rating tool used on a repeatable basis, a behavioral health care plan that gets updated as the patient's status changes, and continuity — the same care team following the same patient month over month. The documentation needs to visibly connect the monthly contact, the plan, and the rating tool's result.

It depends on how and where the contact happened — office, the patient's home, or another telehealth setting each have their own defined POS code, and each can affect facility-versus-non-facility payment. Deciding in advance which POS code applies to each contact type keeps the claim accurate without reconstructing it after the fact.

Yes — many patients receive BHI from their primary or behavioral health practice while also seeing a separate therapist for ongoing psychotherapy. Keeping that concurrent care visible in the BHI record, rather than documenting the two as if they were unaware of each other, is what keeps a reviewer from reading the two claims as duplicated work.
