Medicare reimburses the Collaborative Care Model (CoCM) through a small set of monthly, time-based CPT codes billed by the primary care practice — 99492 for a patient's first month, 99493 for each subsequent month, 99494 as a 30-minute add-on, and G2214 for shorter increments. Payment is tied to how many minutes the care team spends per calendar month, not to face-to-face visits.

CoCM is one of the few behavioral health services Medicare pays for as a defined, recurring benefit. Understanding the codes — and the monthly time thresholds behind them — is the difference between a program that covers its own cost and one that leaks revenue.

What are the CoCM billing codes under Medicare?

Medicare pays for collaborative care through four main codes, all billed by the treating practitioner (usually the primary care physician) once per calendar month:

• 99492 — the *initial* month of CoCM for a patient. Covers the first 70 minutes of care-team time in the first calendar month.
• 99493 — a *subsequent* month. Covers the first 60 minutes of care-team time in any later month.
• 99494 — an *add-on* code for each additional 30 minutes in a given month, billed alongside 99492 or 99493.
• G2214 — a shorter increment covering the first 30 minutes of initial or subsequent care in a month, used when the team hasn't reached the higher thresholds.

The minutes counted are the combined time of the behavioral health care manager and the consulting psychiatrist, plus any qualifying time from the billing practitioner. The care itself does not have to be face-to-face — phone check-ins and the psychiatric consultant's caseload review both count.

How does Medicare set the payment rate?

CoCM codes are paid under the Medicare Physician Fee Schedule (MPFS). Each code is assigned a relative value, which CMS multiplies by an annual conversion factor to produce a national average payment amount. That national figure is then geographically adjusted — the Geographic Practice Cost Index (GPCI) raises or lowers the rate depending on where the practice is located, so the same code pays somewhat more in a high-cost metro than in a rural area.

Two consequences follow. First, there is no single "CoCM rate" — the number depends on the year and the locality. Second, the amounts move every year when CMS updates the fee schedule and the conversion factor. Any dollar figure you see quoted for 99492 or 99493 is a snapshot. Rates change annually; always confirm current CMS values for your locality before modeling revenue.

How much does CoCM pay per patient per month?

As a rough, order-of-magnitude picture — not a quote — the initial-month code (99492) tends to reimburse more than the subsequent-month code (99493), because it covers more minutes, and the add-on (99494) stacks smaller increments on top. In broad terms, a fully managed patient generates a modest monthly amount in the tens of dollars, and the revenue is *recurring* for as long as the patient stays enrolled and the team documents enough time.

The economics work on volume and continuity, not on any single rich claim. One patient-month is small; a panel of actively managed patients billed reliably every month is what makes the model sustainable. Because the exact amounts shift with the annual fee schedule and local adjustment, treat any specific figure as provisional and confirm the current CMS value rather than relying on a number from a prior year.

Why do the monthly time thresholds matter?

CoCM billing is threshold-based, and that design drives the entire economic model. A patient only becomes billable in a given month once the care team logs enough cumulative minutes to reach a code's threshold — for example, the minutes required before 99493 can be billed for a subsequent month.

If the team spends real time but stops just short of a threshold, that effort may not be reimbursable that month. The practical implication for any CoCM program:

• Track minutes per patient, per calendar month. Time doesn't roll over between months.
• Watch patients sitting just below a threshold near month-end, where a short additional contact can move a patient-month from unbillable to billable.
• Document the care-team time carefully, since the claim rests on cumulative minutes, not on a visit.

This is why enrollment volume alone doesn't guarantee revenue. A large panel that regularly falls short of thresholds can bill far less than a smaller, tightly managed one.

How is CoCM reimbursement different from fee-for-service visits?

A standard office visit is billed per encounter. CoCM is billed per *month of management*, based on time spent by a team — much of it outside a face-to-face visit. That difference reshapes how a practice runs the service:

• Revenue depends on consistent monthly engagement, not on getting the patient back into the office.
• The care manager's time is a billable input, so the model funds a role that fee-for-service normally doesn't reimburse.
• Because it's recurring, the value accrues to practices that keep patients enrolled and actively managed month after month, using measurement-based tools (like the PHQ-9 and GAD-7) to justify continued treatment.

Medicare beneficiaries may owe standard cost-sharing (deductible and coinsurance) on CoCM claims, as with other Part B services — another reason to confirm current rules rather than assume.

Frequently asked questions

Which CPT codes are used to bill CoCM to Medicare?

The core codes are 99492 (initial month, first 70 minutes), 99493 (subsequent month, first 60 minutes), 99494 (each additional 30 minutes, add-on), and G2214 (first 30 minutes of initial or subsequent care). They are billed monthly by the treating practitioner based on care-team time.

How much does Medicare pay for 99492?

The amount is set under the Medicare Physician Fee Schedule as a national average, then adjusted for the practice's geographic locality, and it changes every year. Because of that, there is no fixed figure — confirm the current CMS value for your locality before relying on any number.

Who bills the CoCM codes — the psychiatrist or the primary care practice?

The billing practitioner is typically the primary care physician (or another treating practitioner) at the practice, not the consulting psychiatrist. The psychiatric consultant's and care manager's minutes count toward the monthly time, but the claim is submitted under the treating practitioner.

Does the patient have to be seen in person to bill CoCM?

No. CoCM is based on cumulative care-team time in a calendar month, including phone check-ins and the psychiatric consultant's caseload review. It is not tied to a face-to-face visit, though standard Medicare cost-sharing may still apply.

Why doesn't a large enrolled panel automatically mean high reimbursement?

Because billing is threshold-based. A patient-month is only reimbursable once the team logs enough documented minutes to reach a code. Panels that regularly fall just short of the monthly thresholds bill less than smaller, tightly managed ones.
