How Much Revenue Can a Physician Group Earn from CCM? A Worked Example

A physician group with 25 providers, each with 100 enrolled Medicare patients, can bill about $1.86 million a year from the basic Chronic Care Management (CCM) code alone, and about $2.46 million if 40% of those patients also reach one extra 20-minute block. These figures use 2026 national Medicare rates, before locality adjustments and patient cost-sharing.

The math, step by step

CCM is billed per patient, per month. The basic code, CPT 99490, covers the first 20 minutes of clinical staff time in a calendar month. CPT 99439 adds payment for each additional 20 minutes.

To stay conservative, we use $62 for 99490 and $50 for 99439. Published 2026 national figures run slightly higher (for example, $66.13 and $50.44 in one summary of the final fee schedule), and your locality will differ.

Annual revenue = providers × enrolled patients per provider × $62 × 12

The example assumes 100 enrolled patients per provider. That number is illustrative, so replace it with your own panel data.

The add-on column adds enrolled patients × 40% × $50 × 12. For 25 providers, that is 2,500 × 0.40 × $50 × 12 = $600,000 on top of $1,860,000.

What has to be true before you can bill

The math only holds for patients who qualify and whose care is documented. Under CMS guidance:

• The patient has two or more chronic conditions expected to last at least 12 months, with significant risk of decline or death.
• You have the patient’s consent, documented, including that only one practitioner can bill CCM per month and that they can stop at any time.
• New patients, or those not seen in the past year, need an initiating visit first.
• Clinical staff time is tracked and documented every calendar month, under the billing practitioner’s general supervision.

The codes behind the numbers

CCM is a family of codes. Which ones you can bill depends on who does the work and how much time it takes.

Groups build their models on 99490 and 99439 because clinical staff, not physicians, do the work. Codes 99491 and 99437 count only the billing practitioner’s own time, so they rarely scale across a group.

What the work looks like in hours

At group scale, the question is capacity. Each enrolled patient needs at least 20 documented minutes a month.

A 10-provider group needs roughly two full-time people’s worth of pure care time, before outreach and documentation. At $62 per 20 minutes, billable time works out to about $186 per hour before overhead.

That ratio is why CCM is attractive, and why it fails when minutes go unrecorded. A patient with 19 documented minutes in a month generates nothing for that month.

Why scaling CCM across a group is harder than it looks

The formula assumes every eligible patient is found, enrolled and documented every month, at every site and for every provider. In a group, revenue is lost in five places:

1. Finding eligible patients. Chart review does not scale across thousands of patients and multiple EHR instances.
2. Uneven enrollment. One provider enrolls 150 patients while another enrolls 20, because each runs their own process.
3. Time tracking. Minutes spent on care go unrecorded, so patients fall short of the 20-minute threshold.
4. Documentation. Care plans and consent are captured differently by site, which creates audit risk.
5. Billing attribution. Only one practitioner can bill CCM per patient per month, so the group needs a clear rule for who bills.

Each gap shrinks the number of patients you can actually bill, which is the biggest number in the formula.

A second example: how enrollment rate changes the answer

Most groups start from a different number: how many patients are eligible, and what share actually enroll. Suppose a 25-provider group has 5,000 eligible patients and bills 99490 only at $62 per month.

Every 10 points of enrollment adds about $372,000 a year in this example. These shares are illustrative, not benchmarks. Enrollment is usually the number a group can move the most.

How revenue grows from here

• Add-on time. Each extra 20 minutes (99439) adds about $50 per patient per month.
• Complex CCM. CPT 99487 covers the first 60 minutes of complex care at roughly $144 per month, with 99489 for each additional 30 minutes (about $78).
• Other programs. Groups often pair CCM with related programs such as Principal Care Management or remote monitoring. Eligibility and billing rules differ for each, so check them before you plan around them.

Where Clinii fits

For a physician group, the hard part of CCM is not the arithmetic. It is running the same process every month across every provider. Clinii gives groups one care management workflow across every provider: it finds eligible patients, automates enrollment, builds care plans, captures compliant care activity and produces billing-ready output, and it works with 25+ EHRs. Across the platform, Clinii has enabled $1.5B in reimbursement for 1M+ patients.
