There is no single CPT code for case management behavioral health. The right code depends on your service model, payer, and care team structure.
General Behavioral Health Integration uses CPT 99484. The Psychiatric Collaborative Care Model bills through CPT 99492, 99493, 99494, and HCPCS G2214. Medicaid programs often rely on HCPCS codes like T1016 instead.

TLDR: CPT code for case management behavioral health
The primary case management CPT codes for behavioral health are 99484 (General BHI), 99492 (initial CoCM month), 99493 (subsequent CoCM months), and 99494 (CoCM add-on time).
HCPCS G2214 covers CoCM when time falls below the CPT thresholds.
For Medicaid, T1016 and other HCPCS Level II codes apply depending on the state. BHI and CoCM cannot be billed for the same patient in the same month.
The table below shows every primary behavioral health case management billing code at a glance.
| Code | Service | Minimum time | Provider | Payer |
| CPT 99484 | General BHI care management | 20 min/month | Clinical staff under general supervision | Medicare |
| CPT 99492 | Initial CoCM month | 70 min/month | BH care manager + psychiatric consultant | Medicare |
| CPT 99493 | Subsequent CoCM month | 60 min/month | BH care manager + psychiatric consultant | Medicare |
| CPT 99494 | CoCM add-on | Each additional 30 min | BH care manager + psychiatric consultant | Medicare |
| HCPCS G2214 | CoCM base (lower threshold) | 30 min/month | BH care manager + psychiatric consultant | Medicare |
| HCPCS G0323 | BHI for eligible MH professionals | 20 min/month | Clinical psychologists, social workers, MHCs, MFTs | Medicare |
| HCPCS T1016 | Case management services | Varies by state | Varies | Medicaid |
How does general BHI billing work?
General Behavioral Health Integration is the simpler of the two Medicare-recognized models for integrating behavioral health into primary care.
If your practice manages patients with behavioral health conditions but does not operate a formal collaborative care team (with a psychiatric consultant and patient registry), BHI through CPT 99484 is the appropriate billing pathway.
Time threshold
CPT 99484 requires at least 20 minutes of clinical staff time per calendar month.
Qualifying activities include initial assessment or follow-up monitoring (often using validated scales like the PHQ-9 or GAD-7), care plan development and revision, treatment coordination with other providers, and patient outreach.
The 20-minute floor is cumulative — staff can log time across multiple activities within the same month.
Supervision rules
Clinical staff performing BHI services work under general supervision, which means the billing practitioner does not need to be on-site during each activity.
The billing practitioner directs the care plan and bills under their own NPI, but the day-to-day coordination happens at the staff level.
For most primary care practices, the lower supervision requirement makes BHI much easier to implement than CoCM (where psychiatric oversight adds operational complexity that smaller clinics often cannot absorb).
Billing restrictions
BHI (99484) and CoCM codes cannot be billed for the same patient in the same calendar month. A practice can use both models across different patients, but must pick one per patient per month.
An initiating visit — such as an E/M visit, Annual Wellness Visit, or Transitional Care Management visit — is typically required before billing 99484 for the first time.
BHI can be billed alongside Chronic Care Management (CCM, 99490) for the same patient in the same month, provided both sets of requirements are independently met and the time counted toward each code does not overlap.
What does the collaborative care model require?
CoCM is a structured, team-based model designed for patients whose behavioral health needs exceed what general BHI can address.
It requires three participants working together — a treating physician or qualified health care professional, a behavioral health care manager, and a psychiatric consultant — along with a patient registry and regular caseload review.
The higher operational bar produces higher reimbursement, but also means more documentation, more coordination, and more compliance risk if any required element is missing.
Practices that launch CoCM without fully building out the team structure and registry workflow tend to accumulate denials quickly (and reversing those patterns after the fact is far harder than setting up correctly from the start).
The infographic below shows how information flows between the three required CoCM team members and the patient.
CoCM Team Workflow
How the collaborative care team works together
Treating physician
Directs the care plan, orders services, bills under their NPI
BH care manager
Coordinates daily care, tracks registry, engages patients, logs time
Psychiatric consultant
Reviews caseload weekly, recommends treatment changes — does not see patients directly
Patient
Receives coordinated behavioral health care through the team
All three team members + patient registry + weekly caseload review are required for CoCM billing
CPT 99492
CPT code 99492 is the initial-month CoCM code. It covers the first 70 minutes of behavioral health care manager activities, including patient outreach, initial assessment with validated rating scales, treatment plan development, care coordination, and psychiatric consultant review. Practices bill 99492 only during the first calendar month of CoCM services for a given patient.
CPT 99493
After the initial month, CPT 99493 covers the first 60 minutes of care manager activity in each subsequent month. The scope is similar — ongoing monitoring, care plan adjustment, continued coordination, and psychiatric review — but the lower time threshold reflects that initial intake work is already complete.
CPT 99494
When care manager time exceeds the base threshold in either the initial or subsequent month, CPT 99494 captures each additional 30-minute increment.
A first month with 90 minutes would be billed as 99492 + 99494. A subsequent month with 90 minutes would be 99493 + 99494. Practices with high-acuity behavioral health panels regularly bill 99494 alongside the base code.
HCPCS G2214
Not every CoCM patient reaches the 70- or 60-minute threshold every month. HCPCS G2214 covers the first 30 minutes of CoCM activities when time falls short of the CPT requirements.
CMS created G2214 to give practices a billing option for months where meaningful CoCM work happens but does not hit the higher time floors. All other CoCM requirements (team structure, registry, caseload review) still apply when billing G2214.
How do BHI and CoCM compare?
Choosing between BHI and CoCM affects staffing, documentation, reimbursement, and overhead. The comparison below highlights the practical differences that shape that decision.
| Feature | General BHI (99484) | CoCM (99492–99494, G2214) |
| Psychiatric consultant | Not required | Required |
| Patient registry | Not required | Required |
| Weekly caseload review | Not required | Required |
| Clinical staff supervision | General | Direct/general (varies by activity) |
| Minimum monthly time | 20 minutes | 70 min (initial), 60 min (subsequent), 30 min (G2214) |
| Team structure | Billing practitioner + clinical staff | Physician + care manager + psychiatric consultant |
| Best suited for | Lower-complexity behavioral health needs | Complex or treatment-resistant cases |
Many primary care clinics start with BHI because the operational setup is lighter.
Practices that already employ a behavioral health care manager and have access to psychiatric consultation are better positioned to launch CoCM and capture higher reimbursement.
The decision often comes down to whether the practice can sustain the registry tracking and weekly caseload review that CoCM demands (and whether the patient panel justifies that investment).
Which HCPCS codes cover Medicaid case management?
Medicare is not the only payer for behavioral health case management. Medicaid programs across states use their own HCPCS Level II codes, and the rules vary significantly by state and managed-care organization.
The most commonly referenced Medicaid behavioral health case management codes include the following.
- H0031 for mental health assessment
- H2015 for community support services
- H0032 for mental health treatment planning
- T1016 for case management services (used by many state Medicaid programs for behavioral health coordination)
T1016 is frequently misidentified as a CPT code — it is not. T1016 is a HCPCS Level II code, governed by state Medicaid fee schedules rather than the AMA’s CPT system. Billing T1016 under the wrong code set can result in automatic denials.
HCPCS G0323 is a separate Medicare code that allows clinical psychologists, licensed clinical social workers, mental health counselors, and marriage and family therapists to bill BHI services under their own credentials. Eligibility depends on provider type, enrollment status, and current CMS rules — not every behavioral health professional automatically qualifies.
State fee schedules should always be verified before billing Medicaid behavioral health codes. What works in one state may not be recognized in another (and managed-care carve-outs add another layer of complexity).
What documentation supports compliant billing?
Documentation is where behavioral health case management claims either survive or fail on audit. Missing records are the fastest route to post-payment recoupment.
Compliant billing for both BHI and CoCM requires evidence of the following.
- An initiating visit before the first billing month
- Assessment results using validated rating scales
- Treatment coordination notes with other providers
- Care plan revisions when patient outcomes change
- Patient consent for behavioral health integration services
- Cumulative time logs showing staff activities and minutes
- A current behavioral health care plan with measurable goals
CoCM adds three additional documentation requirements.
- A patient registry entry with tracking data
- Documented psychiatric consultant recommendations
- Evidence of regular (typically weekly) caseload review
For most practices, the weak link is time tracking. Staff often perform qualifying activities but fail to log minutes accurately, which means the practice cannot defend the claim if audited.
Building time-tracking into daily workflow — rather than reconstructing logs at month-end — is the difference between sustainable billing and write-offs.
What billing mistakes trigger audits?
Behavioral health case management billing attracts scrutiny because the codes are time-based, team-dependent, and relatively new to many practices. The most common mistakes fall into predictable patterns.
- Submitting T1016 as a CPT code on Medicare claims
- Missing the initiating visit before the first BHI or CoCM claim
- Billing G2214 without meeting all CoCM team and registry requirements
- Logging insufficient time (below the minimum threshold for the code billed)
- Using CPT 99492 beyond the first calendar month instead of switching to 99493
- Submitting CoCM codes without a psychiatric consultant on the care team
- Billing BHI and CoCM for the same patient in the same month
- Failing to maintain a patient registry for CoCM services
The financial risk extends beyond individual claim denials.
Patterns of incorrect billing can trigger Recovery Audit Contractor (RAC) reviews, which look at larger claim sets and can result in significant recoupment.
Practices billing behavioral health codes should run a quarterly internal audit — checking a sample of claims against documentation before an external auditor does. Catching errors in-house is far cheaper than responding to a RAC demand letter.
How do you pick the right behavioral health code?
The right case management CPT code for behavioral health depends on three variables — the care model, the time documented, and the payer. The decision framework below maps each scenario to the correct code.
Code Selection Framework
Which behavioral health code should you bill?
Step 1 — Identify your payer
Medicare — Formal CoCM team in place?
YES — CoCM
First month, 70+ min → 99492
Later months, 60+ min → 99493
Each extra 30 min → 99494
Under threshold, 30+ min → G2214
NO — General BHI
20+ min clinical staff time → 99484
Eligible MH professional billing independently → G0323
Medicaid — Check state HCPCS codes
Case management → T1016
Treatment planning → H0032
Community support → H2015
Verify state fee schedule before billing
Always confirm team structure, documented time, and payer acceptance before submitting any behavioral health claim
Before submitting any behavioral health case management claim, confirm three things.
- The care team structure matches the code’s requirements
- The documented time meets the minimum threshold
- The payer accepts the code you plan to bill
Stop losing revenue on behavioral health billing
Many practices leave money on the table because they either skip behavioral health billing entirely or submit claims with documentation gaps that produce denials.
Whether you’re launching BHI, scaling CoCM, or cleaning up existing behavioral health workflows, accurate coding and solid documentation are what protect your revenue.
- Time tracking systems that hold up under audit
- Documentation that satisfies every CMS requirement
- Denial management for rejected behavioral health claims
- Correct code selection based on your care model and payer

Frequently asked questions
These FAQs address remaining questions not fully covered in the sections above.
CPT 99484 is the primary billing code for General Behavioral Health Integration care management. It covers at least 20 minutes of clinical staff time per calendar month for activities like patient assessment, care coordination, treatment plan management, and follow-up monitoring using validated rating scales. The billing practitioner directs services and bills under their NPI. Unlike CoCM codes, 99484 does not require a psychiatric consultant or patient registry, which makes it the more accessible option for smaller primary care practices.
CPT 99484 covers General BHI — 20 minutes of clinical staff time, no psychiatric consultant required. CPT 99492 covers the initial month of Collaborative Care Management — 70 minutes of behavioral health care manager time, plus a psychiatric consultant, patient registry, and weekly caseload review. CoCM (99492) reimburses at a higher rate but demands a more structured care team and heavier documentation. Practices without psychiatric consultation access typically bill under 99484.
No. T1016 is a HCPCS Level II code, not a CPT code. Many Medicaid programs use T1016 for case management services in behavioral health, but the code is governed by state Medicaid fee schedules rather than the AMA’s CPT code set. Submitting T1016 as a CPT code on Medicare claims will result in a denial. Always verify your payer’s accepted code set before billing, and check state-specific rules for T1016 coverage and rates.
Yes. General BHI (99484) and Chronic Care Management (CCM, 99490) can be billed for the same patient in the same month, provided both sets of requirements are independently met and the time counted toward each code does not overlap. However, BHI and CoCM codes (99492–99494) cannot be billed together for the same patient in the same month — that is the billing exclusivity rule most practices need to track carefully.
CPT 99368 falls within the 99366–99368 range, which covers interdisciplinary team conference codes — not behavioral health case management. The 99366–99368 codes report medical team conferences involving specific provider types. Behavioral health case management should be reported using 99484 (BHI), 99492–99494 (CoCM), G2214, or applicable HCPCS codes depending on the payer. Confusing conference codes with case management codes is a common billing error worth flagging in staff training.
Start by identifying the correct service model (BHI or CoCM) and confirming the payer’s accepted codes. For Medicare, bill 99484 for BHI or 99492/99493/99494 for CoCM based on the month and time documented. Accumulate qualifying staff time throughout the calendar month, document all activities against the care plan, and submit the claim with the billing practitioner’s NPI. For Medicaid, verify state-specific HCPCS codes like T1016 or H0032 before submitting. Every claim should be backed by time logs, care plan notes, and consent documentation.
