For behavioral health practices, 99493 is important because it supports ongoing care after the initial CoCM month. It is not the “first step” in the model; it is the code that reflects continued follow-up, care coordination, monitoring, and treatment adjustments once the patient is already enrolled in collaborative care. That makes accurate time tracking and documentation essential for compliant billing.

What Is CPT Code 99493?

CPT code 99493 is the follow-up psychiatric collaborative care management code. In plain language, it is the billing code used when the care team continues CoCM services in a later month and the behavioral health care manager has provided at least 60 minutes of qualifying work during that calendar month. CMS places this code in the psychiatric CoCM family alongside 99492 for the initial month and 99494 for additional 30-minute increments. The keyword in 99493 is “subsequent.” That means the patient is no longer in the first month of CoCM. Instead, the care team is continuing treatment, monitoring progress, and making changes as needed. CMS’s guidance makes clear that 99493 is tied to subsequent calendar months, not the initial enrollment month.

99493 CPT Code Description

The official Medicare-facing description of 99493 is essentially: follow-up psychiatric collaborative care management, first 60 minutes in a subsequent month of behavioral health care manager activities, in consultation with a psychiatric consultant, and directed by the treating physician or other qualified health care professional. CMS’s 2026 behavioral health integration booklet spells this out directly and also identifies the month-based threshold. In practical billing terms, 99493 is meant to capture the work that happens after the initial CoCM month when the team is still actively managing the patient’s behavioral health needs. This usually includes tracking progress, coordinating care, reviewing treatment response, and planning next steps. The code is designed to reflect the structured, team-based nature of CoCM rather than a single face-to-face appointment.

How 99493 Fits Into Psychiatric Collaborative Care Management

Psychiatric CoCM is a team-based model. CMS describes the team as including three core roles: the treating (billing) practitioner, the behavioral health care manager, and the psychiatric consultant. The model enhances usual care with care management support and regular psychiatric consultation, especially for patients whose conditions are not improving as expected. The billing practitioner directs the care team, oversees treatment, and remains involved in ongoing management and reassessment. The behavioral health care manager performs the hands-on follow-up work such as registry tracking, monitoring, coordination, and brief interventions. The psychiatric consultant contributes specialty psychiatric expertise and treatment recommendations. In CoCM, 99493 is the code that captures the work done in that second, third, or later month of care.

99493 vs 99492 vs 99494

99493 vs 99492 vs 99494 These three codes are often confused, but CMS’s billing summary makes the difference clear:

• 99492 is the initial psychiatric CoCM code for the first 70 minutes in the initial calendar month.
• 99493 is the follow-up psychiatric CoCM code for the first 60 minutes in a subsequent calendar month.
• 99494 is the add-on code for each additional 30 minutes in the calendar month, used with both 99492 and 99493.

A simple way to remember it is this: 99492 = first month, 99493 = later months, and 99494 = extra time beyond the base threshold. CMS also notes that a separate HCPCS alternative, G2214, exists for initial or subsequent CoCM and covers the first 30 minutes per month, but the CPT sequence above is the standard CoCM billing structure many practices focus on.

Who Can Bill CPT Code 99493?

CMS states that physicians and non-physician practitioners (NPPs) whose scope of practice includes E/M services may bill BHI services, and the psychiatric CoCM model is billed by the treating practitioner who directs the team. CMS lists physicians of any specialty, physician assistants, nurse practitioners, clinical nurse specialists, and certified nurse midwives among the practitioners allowed to bill BHI services in the Medicare framework.

The important point is that 99493 is not billed just because a patient has behavioral health needs. The code depends on the structured CoCM arrangement, the right team roles, and the correct month-based time threshold. It also requires that the patient have given consent for BHI services, and CMS says that consent may be verbal as long as it is documented in the medical record.

Time Requirements for 99493

The time rule for 99493 is straightforward: the behavioral health care manager must complete at least 60 minutes of qualifying CoCM work in a subsequent calendar month. CMS’s coding summary lists the threshold directly and confirms that CPT time rules apply to CoCM services.

What counts toward that time? CMS includes work such as registry tracking, weekly caseload consultation, coordination with other treating providers, review of progress and medication recommendations, brief evidence-based interventions, validated rating scales, and relapse-prevention planning. The time is focused on the behavioral health care manager’s activities in consultation with the psychiatric consultant and under the direction of the billing practitioner.

Accurate documentation matters because CoCM is a monthly, time-based service. If the record does not clearly support the required time and service components, the claim can be vulnerable to denial, correction, or audit risk. Good time logs, team notes, and registry documentation make the billing trail much stronger.

Services Typically Included in 99493

CPT 99493 usually includes ongoing follow-up tasks that keep the collaborative care plan active. CMS describes core CoCM activities such as tracking patient follow-up and progress in a registry, coordinating care with the treating practitioner and other mental health providers, reviewing recommendations for changes in treatment, providing brief interventions, and monitoring outcomes with validated rating scales.

In everyday practice, that can mean checking symptom trends, discussing whether a medication change is needed, updating the care plan, speaking with the psychiatric consultant about next steps, and helping the patient stay engaged in treatment. The code is built for ongoing management, not just one isolated contact.

Documentation Requirements for 99493

Strong documentation for 99493 should show the subsequent month, the time spent, and the specific CoCM activities performed. CMS’s materials repeatedly emphasize proper documentation of registry tracking, consultation, coordination, outcome monitoring, and the overall team-based workflow.

At a minimum, the record should support the medical necessity of follow-up CoCM, show that the behavioral health care manager’s work reached the 60-minute threshold, and demonstrate that the psychiatric consultant and treating practitioner were involved in the model as required. If consent was obtained, it should also be documented in the chart.

Common Billing Mistakes to Avoid

One common mistake is billing 99493 too early, before the patient has reached the follow-up month or before the 60-minute threshold is met. Another is confusing 99493 with 99492, which is reserved for the first 70 minutes in the initial month. A third mistake is forgetting that 99494 is an add-on code and should not stand alone.

Practices also run into trouble when documentation is incomplete or when staff mix up the different BHI models. CMS states that psychiatric CoCM and general BHI are separate services, and in many cases you should not bill the general BHI code in the same month as psychiatric CoCM for the same patient. That makes coding workflow discipline especially important.

99493 Billing Tips for Behavioral Health Practices

A strong billing workflow starts with a monthly time tracker for behavioral health care manager activities. That helps the practice know when the 60-minute threshold has been reached and reduces the risk of undercoding or overcoding. CMS’s time-based structure makes this kind of tracking especially useful.

Templates also help. Use a standardized note that captures registry review, care coordination, consultant input, patient outreach, symptom monitoring, and treatment plan changes. Train front-office, clinical, and billing staff to recognize the difference between 99492, 99493, and 99494 so the claim matches the care actually delivered. Verifying payer-specific rules is also smart, because Medicare guidance is the baseline, but other payers may have their own policies.
