Chronic Care Management Billing in 2026: CPT Codes, Medicare Requirements, and How to Bill 99490 and 99491 Correctly

Chronic Care Management billing lets your practice collect a Medicare payment every single month for patients you are already managing. Most practices are not billing it. The ones that are typically earn an extra $66 to $89 per qualifying patient per month, without adding a single visit to the schedule.

This guide covers the 2026 CPT codes, the Medicare eligibility requirements, the documentation your billing team needs, and the most common reasons claims get denied. If you have patients with two or more chronic conditions on Medicare Part B, you almost certainly qualify.

What Is Chronic Care Management Billing?

Chronic Care Management (CCM) is a Medicare program that pays physicians and qualified clinicians for the non-face-to-face care coordination they provide to beneficiaries with multiple chronic conditions. CMS introduced CCM billing in 2015 because managing patients with diabetes, hypertension, COPD, heart failure, and similar conditions requires significant time outside of office visits. The program creates a billing mechanism for that work.

To qualify, a patient must have two or more chronic conditions that are expected to last at least 12 months and that place the patient at significant risk of functional decline or death. Medicare Part B covers the service, and your practice bills using the CPT codes below.

2026 CCM CPT Codes and Reimbursement Rates

CMS updates the Medicare Physician Fee Schedule each January. The 2026 national average rates for CCM CPT codes are as follows.

Rates are based on the 2026 Medicare Physician Fee Schedule national averages. Your actual reimbursement depends on your geographic location and whether you participate in a value-based care program.

A practice with 150 qualifying patients billing 99490 every month is collecting roughly $9,900 per month, or $118,800 per year, from work the clinical staff is largely already doing.

Medicare Eligibility Requirements for CCM

Your practice must meet five requirements to bill CCM to Medicare.

1. Two or more chronic conditions. The patient must have at least two chronic conditions expected to last 12 months or until death that place them at significant risk of acute exacerbation, functional decline, or death. Examples include diabetes, hypertension, chronic kidney disease, COPD, congestive heart failure, depression, and arthritis.
2. Written patient consent. You must obtain written or verbal consent from the patient before the first billing period. The consent must explain the nature of CCM services, that only one provider can bill CCM per month, and the patient’s right to stop the service at any time.
3. A comprehensive care plan. You must create, review, and revise an individualized care plan for the patient. The plan must be accessible to the care team 24 hours a day.
4. 24/7 access and care continuity. Your practice must provide patients with a way to reach a clinical staff member around the clock, not just during office hours.
5. Documented monthly time. You must document the specific date, start and end time, and nature of each CCM activity for the month. CPT 99490 requires at least 20 minutes of clinical staff time. That time does not include face-to-face visit time.

Only one provider can bill CCM for a given patient in a given calendar month. If the patient sees a specialist who also attempts to bill CCM, one claim will be denied. This makes it important to confirm your practice is the designated CCM provider for each qualifying patient.

How to Bill CCM Correctly: Step by Step

The billing process for CCM has several moving parts. Missing any one of them is the most common reason claims fail.

1. Identify qualifying patients. Run a report in your EHR for Medicare Part B patients with two or more chronic condition diagnoses. These are your CCM candidates.
2. Obtain consent. Document written or verbal consent in the patient’s chart. Note the date, who obtained it, and that the patient understands the terms.
3. Create the care plan. Build the comprehensive care plan. It must include the patient’s problem list, expected outcome, measurable goals, and the community services the patient needs.
4. Track time each month. Assign a care coordinator to log all CCM activities: phone calls, care coordination, medication management outreach, referral follow-up. Log the date, duration, and a brief note for each activity.
5. Verify the 20-minute minimum is met. Before the end of the billing period, confirm the total time for that patient crosses the 20-minute threshold (or 30 minutes if billing 99491).
6. Submit the claim. Bill CPT 99490 (or the appropriate code) once per calendar month. Include the ICD-10 diagnosis codes for the patient’s chronic conditions. Use place of service code 11 (office) or the appropriate telehealth modifier if applicable.
7. Store documentation for audits. Medicare audits CCM claims. Keep time logs, the signed consent, and the care plan accessible in the patient record.

Top Reasons CCM Claims Are Denied

CCM denials follow predictable patterns. Most practices encounter the same four or five issues when they start billing.

• No documented consent. Medicare requires documented patient consent before the first billing month. Claims submitted without proof of consent are denied on audit.
• Time not tracked by individual patient. Logging time as a general CCM block rather than by specific patient fails the documentation requirement. Every minute of time must be tied to an individual patient in the record.
• Billing the same month as an Annual Wellness Visit. You cannot bill 99490 in the same month you bill G0438 or G0439 (Annual Wellness Visit). Plan your billing calendar accordingly.
• Duplicate billing conflict. Another provider billed CCM for the same patient in the same month. The second claim is automatically denied. Confirm with patients whether another practice is already managing their CCM.
• Insufficient diagnosis codes. The claim must reflect the two chronic conditions that qualify the patient. Submitting vague or incomplete ICD-10 codes raises audit flags.
• Missing care plan in the record. Medicare auditors will request the care plan. If it does not exist or has not been updated within the required timeframe, the claim can be recouped.

In-House vs Outsourced CCM Billing: The Real Staffing Cost

The biggest barrier practices face with CCM is staffing the care coordination function. The monthly time tracking, patient outreach, and documentation requirements take a dedicated person. For many practices, especially those with fewer than 200 eligible patients, building that infrastructure in-house costs more than the revenue it generates.

Consider a practice with 120 qualifying CCM patients. At 99490 rates, that is roughly $7,920 per month in potential revenue. Managing that population requires approximately 40 hours of care coordinator time per month at minimum. At $22 per hour, that is $880 in direct labor alone, before EHR licenses, management time, and training. The math works, but only if billing and documentation are done correctly the first time. Missed months, denied claims, or recoupments after an audit can erase that margin quickly.

Outsourcing CCM billing to a specialized RCM team shifts that operational burden. The billing company manages time tracking, claim submission, denial follow-up, and audit documentation. The practice keeps the revenue and the patient relationship without building a new internal department.

How Much Revenue Are You Leaving Uncaptured?

According to CMS data, the average primary care practice has between 40% and 60% of its Medicare population qualifying for CCM based on chronic condition burden. Most practices bill for fewer than 10% of their eligible patients.

A practice with 300 Medicare patients likely has 120 to 180 qualifying patients. At $66 per patient per month, that is $95,040 to $142,560 per year in Medicare payments available through CCM alone. The work is largely happening already. The time tracking and billing infrastructure is the gap.

That gap is exactly what a specialized medical billing company helps close.

Frequently Asked Questions

Can a nurse practitioner bill CCM under Medicare?

Yes. Nurse practitioners, physician assistants, clinical nurse specialists, and certified nurse midwives can all bill CCM services under Medicare Part B. The services must be provided within their scope of practice and applicable state law.

What is the difference between CPT 99490 and 99491?

CPT 99490 covers at least 20 minutes of clinical staff time (such as a nurse or medical assistant) performing CCM services under physician supervision. CPT 99491 covers at least 30 minutes of the physician’s or qualified clinician’s own time personally performing CCM services. The reimbursement rate for 99491 is higher because it requires direct clinician involvement rather than delegated staff time.

Can CCM be billed in the same month as a regular office visit?

Yes. CCM can be billed in the same month as an E/M office visit, as long as the CCM time logged does not include time from the face-to-face visit itself. The activities must be distinct. This is a common point of confusion, but it is not a problem as long as your documentation separates the two.

Does Medicare require a specific software platform for CCM?

No. Medicare does not require any particular CCM software. The requirements are documentation-based: consent, care plan, monthly time log, and 24/7 patient access. Whether you track that in your EHR, a dedicated CCM platform, or a structured spreadsheet is up to your practice. What matters is that the documentation exists and is retrievable during an audit.

What happens if we miss a month of billing for a CCM patient?

You simply cannot bill for that month. CCM is billed per calendar month, and you can only bill for months where the documented time requirement was met. There is no retroactive billing. Missing a month means that revenue is gone for that billing period. This is why consistent monthly workflows, ideally managed by a dedicated team, matter so much for CCM revenue capture.

How do we handle CCM for patients who see multiple specialists?

Only one provider can bill CCM for a given patient in a given calendar month. Your practice should confirm with patients at consent that you are taking on the CCM billing role. If a specialist is already billing CCM for that patient, your claim will deny. It is worth checking Medicare remittance data when you first start a patient on CCM to confirm no conflict exists.
