What Are the BHI Billing Requirements?
Quick Answer
Behavioral Health Integration (BHI) billing under CPT 99484 requires four elements: (1) a patient with a diagnosed behavioral health condition (depression, anxiety, PTSD, substance use disorder, etc.) being managed by the billing provider, (2) at least 20 minutes of clinical staff time per month on behavioral health care management activities, (3) documented patient consent, and (4) a behavioral health care plan using validated assessment tools like the PHQ-9 or GAD-7. The 2026 reimbursement for 99484 is approximately $49 per patient per month. Unlike CCM, BHI does not require two chronic conditions — a single behavioral health diagnosis qualifies. NPIxray analysis shows only 4.2% of primary care providers bill any BHI code, despite 20-30% of Medicare patients screening positive for depression or anxiety. This represents one of the most under-billed Medicare services available. Source: NPIxray analysis of 1.175M Medicare providers and 8.15M billing records.
Patient Eligibility Criteria
BHI eligibility requires a diagnosed behavioral health condition that is being actively treated or managed by the billing provider. Qualifying conditions include major depressive disorder, generalized anxiety disorder, PTSD, bipolar disorder, substance use disorders, ADHD, eating disorders, adjustment disorders, and other DSM-5 diagnoses.
Unlike CCM (which requires 2+ chronic conditions), BHI requires only a single behavioral health diagnosis. The patient does not need other comorbid chronic conditions. However, patients who have both behavioral health conditions AND chronic medical conditions can be enrolled in BOTH BHI and CCM simultaneously — just track time separately for each program.
Time and Activity Requirements
To bill 99484, clinical staff must spend at least 20 minutes per calendar month on behavioral health care management activities for the patient. Qualifying activities include: systematic assessment using validated tools (PHQ-9 for depression, GAD-7 for anxiety, AUDIT-C for alcohol use), behavioral health care plan development and revision, patient outreach and engagement about mental health concerns, medication monitoring and side effect assessment, coordination with therapists and psychiatrists, crisis intervention planning, safety risk assessments, and referrals to community behavioral health resources.
Activities that do NOT count: scheduling appointments, administrative tasks, time spent on separately billed services, and general medical care management (which counts toward CCM instead). Time must be tracked with cumulative logs or start/stop documentation, similar to CCM requirements.
Consent and Documentation
Patient consent must be obtained and documented before billing. The consent should explain what BHI services include, that only one provider can bill BHI per month, applicable cost-sharing (approximately $10 coinsurance per month), and the patient's right to withdraw consent at any time. Verbal consent is acceptable but must be documented with the date, who obtained it, and what was discussed.
Documentation requirements for each billing period include: the validated screening tool results (PHQ-9 score, GAD-7 score, etc.), the behavioral health care plan with current status and goals, time logs showing 20+ minutes of qualifying activities, and a summary of care management activities performed. Most EHR systems support BHI-specific templates that streamline this documentation.
Screening as the Gateway to BHI Revenue
Universal behavioral health screening is the most effective way to identify BHI-eligible patients at scale. Implementing the PHQ-2 (two-question depression screener) at every Medicare visit takes 30 seconds and identifies patients who need the full PHQ-9. Research shows 20-30% of primary care Medicare patients screen positive for depression or anxiety.
For a practice with 400 Medicare patients, that is 80-120 patients potentially eligible for BHI. At $49 per patient per month, enrolling even half of those patients generates $23,520-$35,280 in annual revenue. The screening workflow should be embedded into your standard intake process — MA administers the PHQ-2, positive screens trigger the full PHQ-9, and positive PHQ-9 results initiate a BHI enrollment conversation.
BHI vs. Collaborative Care Model (CoCM)
99484 (General BHI) and the Collaborative Care Model codes (99492/99493/99494) are two different billing pathways for behavioral health services. General BHI (99484) requires no consulting psychiatrist, pays $49/month, needs only 20 minutes of care management time, and can be performed by a wide range of clinical staff under general supervision.
The CoCM codes pay significantly more (99492 = $164 initial month, 99493 = $130 subsequent months) but require a three-person care team: the billing provider, a behavioral health care manager (LCSW, RN, or psychologist), and a consulting psychiatrist who reviews cases weekly. Most practices start with 99484 and graduate to CoCM once they have the infrastructure and patient volume to justify the psychiatric consultant relationship.
Frequently Asked Questions
Can you bill BHI and CCM for the same patient?
Yes. BHI and CCM can be billed for the same patient in the same month, provided the time is tracked separately. A patient with diabetes, hypertension (CCM-qualifying) and depression (BHI-qualifying) could generate $115+ per month from combined CCM and BHI billing. The key is that BHI activities must be specific to the behavioral health condition.
Who can perform BHI activities?
For 99484, clinical staff including RNs, LPNs, LCSWs, psychologists, and trained MAs can perform BHI activities under general supervision of the billing provider. The physician does not need to personally deliver the 20 minutes of care management. For CoCM codes (99492-99494), a designated behavioral health care manager is required.
Does BHI require a psychiatrist?
No, not for 99484 (General BHI). A consulting psychiatrist is only required for the Collaborative Care Model codes (99492-99494). This makes 99484 the easiest behavioral health billing code to implement in primary care settings without specialized behavioral health staffing.
