Collaborative Care Model (CoCM) Billing

What the Collaborative Care Model pays for

The Collaborative Care Model (CoCM) brings behavioral health treatment into a primary care or other medical practice. A treating practitioner leads the care, a behavioral health care manager works with the patient between visits, and a psychiatric consultant reviews the caseload and advises on treatment. Collaborative care billing pays the treating practitioner for that team's monthly work.

Unlike a psychotherapy visit, CoCM is billed per calendar month based on care manager time. The claim goes out under the treating practitioner, even though most of the minutes are spent by the care manager and the psychiatric consultant.

Medicare has paid for CoCM since 2017, and many commercial and Medicaid plans now cover the same codes. Coverage and cost-sharing outside Medicare vary, so check each plan before enrolling patients.

CoCM billing codes 99492, 99493, 99494 and G2214

Code	Period	Care manager time described
99492	First calendar month of behavioral health care manager activities	First 70 minutes of initial psychiatric collaborative care management
99493	Each subsequent month	First 60 minutes of subsequent psychiatric collaborative care management
99494	Initial or subsequent month (add-on)	Each additional 30 minutes, reported with 99492 or 99493
G2214	Initial or subsequent month	First 30 minutes of psychiatric collaborative care management (Medicare HCPCS code)

CMS created G2214 for months when the care manager spends less time than 99492 or 99493 requires, which often happens when a patient is starting out or stepping down. Many commercial payers do not recognize G2214, so check before using it outside Medicare.

Time counts only for care manager activities: outreach and engagement, the initial assessment, entering the patient in a registry and tracking follow-up, participation in the weekly caseload review with the psychiatric consultant, and brief interventions such as behavioral activation or motivational interviewing. CMS's behavioral health integration FAQs explain how much time beyond each code's threshold must be reached before the next code or add-on unit can be reported.

Behavioral health integration billing with 99484

Some practices provide integrated behavioral health care without a full CoCM team. CPT 99484 covers general behavioral health integration (BHI): at least 20 minutes per calendar month of clinical staff time, directed by a physician or other qualified health care professional, for a patient with a behavioral health condition.

Required elements of behavioral health integration billing under 99484 include an initial assessment or follow-up monitoring using validated rating scales, behavioral health care planning with revision for patients who are not improving, facilitation and coordination of treatment such as psychotherapy or psychiatric consultation, and continuity of care with a designated member of the care team.

Medicare also recognizes G0323 for general BHI performed by a clinical psychologist or clinical social worker, for at least 20 minutes per calendar month. Confirm which practitioner types each payer allows for 99484 and G0323.

Choosing between CoCM and general BHI

Feature	CoCM (99492-99494, G2214)	General BHI (99484)
Team	Treating practitioner, behavioral health care manager, psychiatric consultant	Treating practitioner and clinical staff
Registry	Required for tracking patient follow-up and progress	Not required
Psychiatric consultant	Required, with regular caseload review	Not required
Time unit	70 or 60 minutes plus 30-minute add-ons, or 30 minutes with G2214	At least 20 minutes per month
Typical use	Structured program with measurement-based care	Lighter integration or practices building toward CoCM

CMS guidance does not allow CoCM and general BHI to be billed for the same patient in the same month. Practices can bill chronic care management for the same patient in the same month as long as the time and activities counted are not double-counted.

Initiating visit, consent and cost-sharing

For Medicare, an initiating visit is required for new patients and for patients not seen by the billing practitioner within the past year. Qualifying visits include a comprehensive E/M visit, an annual wellness visit, the initial preventive physical exam or a transitional care management visit. The initiating visit is billed separately and is not part of the CoCM or BHI time.

Before services start, the practice must get the patient's consent, which may be verbal, and document it in the record. The consent discussion should explain that the patient may owe cost-sharing for each month billed, that the patient can stop at any time, and that the care team, including the psychiatric consultant who may never meet the patient, will share information.

Patients who are surprised by a monthly charge are a common source of complaints. A short written explanation at enrollment helps; our patient billing and collections page describes how statements and payment questions are handled.

Time tracking and documentation

• Log every care manager contact with date, duration, activity and who performed it.
• Record the psychiatric consultant's caseload review and resulting recommendations.
• Keep rating scale scores, such as PHQ-9 or GAD-7, in the registry and the chart.
• Total time at month end, then select the code and add-on units from that total.
• Keep time for separately billed services, such as psychotherapy or an E/M visit, out of the CoCM total.
• Bill once per month, after the month closes, using a date of service the payer accepts.

Monthly billing means a missed month cannot be fixed by adding minutes to the next one. A month-end reconciliation of the registry against claims prevents lost months.

Watch the transition from the first month to later months. The first month of care manager activity in an episode of care is reported with 99492, and every later month in that episode with 99493. Under CMS guidance, an episode ends when the patient meets the treatment goals, is referred for direct psychiatric care, or has no CoCM services for 6 consecutive months; a new episode after that starts again with 99492. Commercial payers may set their own rules, so check their guidance.

Common collaborative care billing denials

Denial	Cause	Prevention
Missing initiating visit	No qualifying visit within the past year	Schedule the initiating visit before enrollment
Add-on without primary code	99494 billed without 99492 or 99493	Report 99494 only with its primary code on the same claim
Code not recognized	G2214 billed to a payer that does not accept it	Check payer code lists before billing
Same-month conflict	CoCM and 99484 billed for the same patient in one month	Assign each patient to one model per month
Insufficient time	Minutes below the code threshold	Reconcile time logs before code selection
