Behavioral health integration: the business case

The business case for behavioral health integration (BHI) rests on a simple fact: Medicare pays primary care practices monthly for structured behavioral health care management, as long as the practice runs a defined model with the right team, documents consent, and meets time and content requirements. There are two ways to do it. General BHI (CPT 99484) needs at least 20 minutes of clinical staff time a month and can run without a psychiatric consultant. The Psychiatric Collaborative Care Model, or CoCM (CPT 99492, 99493, 99494, and HCPCS G2214), pays more per patient but requires a behavioral health care manager, a psychiatric consultant, a registry, and weekly caseload review. Both are described in the CMS Behavioral Health Integration Services booklet (MLN909432, January 2026).

Whether either model pays off for your practice depends on things only you can measure: how many patients screen positive, how many enroll and stay engaged, what your staff cost, and your local fee schedule. This article lays out the rules in force for calendar year 2026 and a way to build the financial model from your own data, without borrowed ROI claims.

Who qualifies and who can bill

According to the CMS booklet, a patient may be eligible for BHI services if they have an identified mental, behavioral, or psychiatric health condition, including substance use disorder, that requires behavioral health assessment, care planning, and interventions. The condition can be pre-existing or diagnosed and refined over time. Patients may also have medical conditions the practitioner manages, but those are not an eligibility requirement.

BHI is billed by physicians of any specialty and by non-physician practitioners whose scope includes evaluation and management services: nurse practitioners, physician assistants, clinical nurse specialists, and certified nurse midwives. Services the billing practitioner does not personally perform are assigned general supervision, so the practitioner does not have to be physically present while care team members work.

Before BHI starts, the billing practitioner holds an initiating visit. Qualifying visits are an annual wellness visit, an initial preventive physical exam, a comprehensive E/M visit, or a transitional care management visit. For HCPCS G0323, the general BHI code for clinical psychologists and clinical social workers, the psychiatric diagnostic evaluation (CPT 90791) serves as the initiating visit.

Consent and cost sharing

The booklet sets out the consent rules. Before services begin, the patient must give the billing practitioner permission to consult with relevant specialists, including a psychiatric consultant, and the practitioner must tell the patient that cost sharing applies to both face-to-face and non-face-to-face services. Consent can be verbal, but it must be documented in the medical record. A new consent is needed only if the patient changes billing practitioners.

Explain cost sharing in terms of what the patient gets each month: regular check-ins, a named care manager, and treatment changes without waiting for the next visit. Record who explained it, when, and what the patient decided.

General BHI versus the Collaborative Care Model

The two models differ mainly in team structure and measurement discipline. A side-by-side view for 2026:

• Required team. General BHI: the billing practitioner, alone or with clinical staff. CoCM: the treating practitioner, a behavioral health care manager, and a psychiatric consultant.
• Monthly time. General BHI (99484): at least 20 minutes of clinical staff time per calendar month. CoCM: 70 minutes of care manager time in the first month (99492), 60 minutes in later months (99493), each additional 30 minutes (99494), or G2214 for the first 30 minutes in a month.
• Measurement. General BHI: validated rating scales for initial assessment or follow-up monitoring. CoCM: validated rating scales plus a registry used to track every patient's follow-up and progress.
• Specialist input. General BHI: psychiatric consultation is optional. CoCM: weekly caseload consultation with the psychiatric consultant is a required element.
• Typical fit. General BHI: practices starting out, or treating milder conditions with existing staff. CoCM: practices ready to treat depression, anxiety, and similar conditions to target with a dedicated care manager.

The two cannot be billed for the same patient in the same month, but the booklet notes it may be appropriate to bill general BHI in some months and CoCM in others for the same patient. CPT time rules apply to both. G2214 exists for months when CoCM is delivered but the 99492 or 99493 time is not reached, for example when a patient is hospitalized or referred to specialty care partway through the month.

What each CoCM team member actually does

The CMS booklet defines each role:

• Behavioral health care manager: has formal education or specialized training in behavioral health, such as social work, nursing, or psychology. Administers rating scales, builds and revises the care plan, delivers brief interventions such as behavioral activation or motivational interviewing, maintains the registry, and consults with the psychiatric consultant. Administrative or clerical time does not count toward the threshold.
• Psychiatric consultant: a medical professional trained in psychiatry and qualified to prescribe the full range of medications. Reviews patients' clinical status, advises on diagnosis and treatment changes, and recommends referral for direct psychiatric care when indicated. Can be, and typically is, remote, and is not generally expected to see patients directly.
• Treating practitioner: directs the care manager, prescribes, treats medical conditions, makes referrals, and stays involved through ongoing oversight and reassessment.
• Patient: an active member of the team, not a passive recipient.

A CoCM episode ends when the patient meets treatment goals, fails to meet them and is referred for direct psychiatric care, or goes 6 consecutive months without CoCM services. The model behind these codes was developed at the University of Washington, and the AIMS Center reports that more than 90 randomized controlled trials and several meta-analyses have found it more effective than usual care for depression, anxiety, and other behavioral health conditions. Its core principles are a patient-centered team, population-based care through a registry, measurement-based treatment to target, evidence-based treatments, and accountability for outcomes.

What changed for 2026

The CY2026 Physician Fee Schedule final rule added three optional add-on codes for practices that also bill Advanced Primary Care Management (APCM): G0568 (based on 99492, initial month of CoCM), G0569 (based on 99493, subsequent months of CoCM), and G0570 (based on 99484, general BHI). They are billed only when the same practitioner reports an APCM base code (G0556, G0557, or G0558) in the same month, and they do not require counting minutes. CMS did not create an add-on for 99494, because the APCM codes do not count time.

Two cautions. First, CMS said in the rule that it still expects the care delivered to be documented in the medical record, so dropping the time requirement does not drop the documentation. Second, the time requirements for 99492, 99493, and 99484 remain in place whenever those codes are billed on their own, outside APCM. If you run APCM, our APCM program page explains how the monthly bundle works.

Looking ahead, the CY2027 proposed rule, published July 16, 2026, proposes higher work values for the CoCM codes, for example raising the work RVU for 99492 from 1.88 to 2.75 and for 99493 from 2.05 to 2.26, along with conforming changes to G2214, G0568, and G0569. These are proposals only and do not affect 2026 claims.

Building the financial model from your own data

A credible business case uses your panel and your costs. Work through these steps, and price every code with the CMS Physician Fee Schedule look-up tool for your locality rather than a national average from an article:

• Step 1, find the population. Count patients with a behavioral health diagnosis in your EHR and your current screening rate at routine visits. If screening is inconsistent, fix that first, because enrollment cannot exceed identification.
• Step 2, estimate enrollment and retention. Use a small pilot to measure how many eligible patients consent and how many are still engaged three months later. Do not assume a rate.
• Step 3, check capacity in minutes. CoCM needs at least 60 care manager minutes per patient in subsequent months. Divide the minutes a care manager can spend on patient work each month by that figure to get a realistic ceiling on monthly CoCM patients, before allowing for initial months at 70 minutes.
• Step 4, price the services. Multiply expected billable patient-months by locality rates for 99484, or for 99492, 99493, and 99494 as appropriate, and subtract an allowance for patients who decline cost sharing.
• Step 5, add the costs. Care manager salary and benefits, psychiatric consultant hours for weekly caseload review, registry or software costs, and the time billing staff spend on claims and denials.
• Step 6, decide on a model. If the CoCM minutes and consultant cost do not work at your volume, general BHI with existing clinical staff is a legitimate starting point.

If you hold value-based contracts that measure depression screening or follow-up, integrated care can support those measures, but only your contract terms say what that is worth.

An operational checklist before launch

• Validated rating scales chosen and built into the visit and follow-up workflow.
• Documented consent script covering specialist consultation and cost sharing.
• A named care manager for each patient, with a way for patients to reach them.
• A registry that shows each patient's last contact, latest scale score, and whether they are improving.
• A weekly caseload review on the calendar with the psychiatric consultant, with recommendations recorded.
• Time logs kept separate from chronic care management and remote monitoring logs, so no minute is counted twice.
• A referral pathway for patients who need direct psychiatric care.

Behavioral health also shapes chronic disease management, which is why many practices launch BHI alongside chronic care management. Hoss Care supports this work with follow-ups, documentation, and care team coordination in one place, and its behavioral health integration program and Collaborative Care service are built around the requirements above. Software can flag a missed follow-up or a worsening score, but the care manager, consultant, and treating practitioner make and sign every clinical decision.
