How CCM Billing Works | Zenith Care Solutions

Chronic Care Management adds a monthly recurring revenue stream to any practice managing Medicare patients with two or more chronic conditions. The billing mechanics are straightforward once the workflow is set up, but the sequence matters: missing a step early leads to denials later.

This guide walks through the five billing steps in order and flags the most common mistakes practices make in each one.

What is CCM billing?

CCM billing refers to the process of claiming reimbursement from Medicare for non-face-to-face care coordination services delivered to eligible patients each calendar month. The work (phone calls, care-plan updates, medication reconciliation, referral coordination, patient education) is performed by clinical staff between office visits. The physician does not need to be present for most of it.

The base code, CPT 99490, covers the first 20 minutes of qualifying clinical staff time in a month. Add-on code CPT 99439 covers each additional 20-minute increment, up to twice per month. Complex CCM codes (99487 and 99489) apply when the patient's conditions require substantial revision of the care plan and a physician or other qualified provider spends the time.

For a breakdown of the individual CPT codes and 2026 reimbursement rates, see the CPT 99490 billing guide.

Step 1: How do you confirm patient eligibility?

A patient is eligible for CCM when all of the following are true:

Medicare Part B enrollment: the patient is covered by Medicare Part B, not only Part A.
Two or more chronic conditions: the conditions are expected to last at least 12 months or until the patient's death, and they place the patient at significant risk of death, acute exacerbation, or functional decline.
Prior face-to-face visit: the patient has been seen in person by the billing provider (or the provider's group) within the past 12 months. A new patient or a patient seen by a different group requires a transitional or annual wellness visit before CCM enrollment.
No concurrent billing conflict: the patient is not already enrolled in a Comprehensive Primary Care Plus (CPC+) or similar program that would prohibit CCM billing by the same practice.

The practical step: pull your Medicare Part B panel and filter by documented chronic diagnoses (ICD-10 codes) in the EHR. Patients with two or more chronic condition codes active on the problem list are your candidate list.

Step 2: How do you obtain and document patient consent?

CMS requires informed verbal or written consent before the first billable month. The consent conversation must cover:

What CCM is and what the practice will do each month
That only one provider may bill CCM for the patient in a given month
The patient's Medicare cost-sharing obligation (20 percent coinsurance applies to CCM, unless the patient has supplemental coverage)
The patient's right to revoke consent at any time without affecting other care

The consent must be documented in the patient's medical record. A note in the EHR with the date, who obtained consent, and the topics covered is sufficient for verbal consent. A signed form is stronger and easier to produce during an audit.

Critical rule: Do not bill any CCM codes until consent is documented. Claims submitted without consent documentation are recoverable by Medicare on audit.

Step 3: How do you deliver and log the required time?

The minimum for CPT 99490 is 20 minutes of qualifying clinical staff time within a single calendar month. The clock resets on the first day of each month.

What qualifies:

Telephone calls with the patient or their caregiver about care coordination
Medication management and reconciliation
Care plan review and updates
Coordination with other providers (referrals, specialist communication, lab follow-up)
Patient education related to chronic condition management
Communication between care team members on the patient's behalf

What does not qualify:

Face-to-face office visit time (that is billed separately under E/M codes)
Time spent on administrative tasks not directly related to care coordination
Time logged by non-clinical staff (scheduling, billing)

The time must be logged in the EHR with the date, activity performed, and duration. A generic note ("called patient, 5 minutes") is risky. A specific note ("patient called to report blood pressure readings above 150/90 three days in a row; reviewed current medication regimen, advised to monitor and return if readings remain elevated, updated care plan note") is defensible.

Step 4: How do you submit the claim?

CCM claims are submitted on a CMS-1500 claim form or its electronic equivalent through your clearinghouse. Key fields:

CPT code: 99490 for the base 20-minute increment. Add 99439 for each additional 20 minutes, up to twice.
Date of service: the last date of clinical staff activity in the month, or the last day of the month. Many practices use the last day of the month as the date of service for consistency.
Place of service: 11 (Office), even if the staff member performed the work remotely. CCM is billed under the office where the care relationship exists.
Provider NPI: the billing provider NPI. The supervising physician's NPI, not the clinical staff member's NPI, unless the staff member is a qualified non-physician practitioner billing independently.
Diagnosis codes: the primary chronic condition ICD-10 codes that qualify the patient. List them in the order of clinical significance.

One claim per patient per calendar month. Do not submit the claim before the month ends unless all time has been documented and no further CCM work will be performed in that month.

Step 5: How do you track reimbursement and reconcile payments?

Medicare processes CCM claims under the Medicare Physician Fee Schedule. The national average for CPT 99490 in 2026 is approximately $66 per enrolled patient per month, but the actual payment varies by Medicare locality (geographic adjustment factor) and the provider's Medicare participation status.

Reconciliation steps each month:

Run an aging report on CCM claims submitted, tracking which have been paid, denied, or are still pending.
Review denial codes. Common denial reasons: missing consent documentation, patient already enrolled by another provider, insufficient time documented, or the patient's Medicare coverage lapsed.
Refile or appeal denials within 120 days of the original remittance advice date. Documentation denials can often be corrected by attaching the supporting EHR note.
Reconcile against expected revenue. For a 100-patient CCM panel at the 99490 rate, the expected monthly revenue is roughly $6,600 (national average). Significant shortfalls usually signal under-documentation rather than coverage issues.

Use your practice management system or a dedicated CCM tracking spreadsheet to monitor enrollment status, monthly activity logs, claims submitted, and payments received.

What billing mistakes cause the most CCM denials?

In order of frequency:

| Mistake | What happens | How to prevent it | |---|---|---| | No documented consent | Claim is recoverable on audit | Obtain consent before billing; document date and topics in EHR | | Fewer than 20 minutes documented | Code 99490 denied; 99439 add-ons have no base to attach to | Log time on every CCM activity; do not bill short months | | Duplicate billing by another provider | Claim denied; only one provider can bill CCM per patient per month | Check enrollment status before adding a new patient | | Wrong place of service code | Claim rejected or paid at wrong rate | Use POS 11 consistently for outpatient CCM | | Non-qualifying activities logged | Documented time does not meet the threshold on audit | Train staff on what qualifies; review documentation monthly | | Date of service in next calendar month | Claim assigned to wrong billing period | Submit in the same calendar month the service was delivered |

Who in the practice can perform CCM work?

CCM is a "principal care" or "incident to" service. Clinical staff who can perform and document CCM time include:

Registered Nurses (RNs)
Licensed Practical Nurses (LPNs)
Medical Assistants (MAs), in many states
Care coordinators with clinical training

The work must be performed under the general supervision of the billing physician or qualified non-physician practitioner, meaning the physician is available by phone but does not need to be on-site during every activity. Check your state's scope-of-practice rules and your MAC's guidance for any additional requirements in your region.

Physicians and nurse practitioners can also perform CCM themselves, but the efficiency gain comes from delegating to clinical staff and freeing physician time for higher-complexity billable work.

Can you outsource CCM billing and coordination?

Yes. Many practices contract with a CCM vendor to handle patient enrollment, monthly care coordination calls, care plan maintenance, time logging, and claim submission. The physician retains oversight and the patient relationship; the vendor's clinical staff performs the day-to-day coordination work under a business associate agreement.

The key compliance requirement: the vendor must maintain documentation standards that match your MAC's requirements. If the vendor's time logs would not survive an audit, the practice bears the recoupment risk, not the vendor.

Zenith handles all five steps end-to-end: enrollment screening, consent workflows, monthly coordination, time documentation, and claim-ready encounter summaries your billing team submits. Book a 15-minute call to see how the workflow fits your EHR and panel size.
