Chronic care management pays for the phone calls, medication reviews and handoffs your staff already make between visits, and it pays per calendar month instead of per encounter. What the claim needs is a time record, a care plan that lives in the chart, a consent documented before the first bill, and a clinician who discussed the program in person. Miss one and the note stops describing a billable service.
What this covers
- The patient test is clinical: two or more chronic conditions expected to last at least 12 months that place the patient at significant risk of death, acute exacerbation or decompensation, or functional decline.
- Time is counted per calendar month, and the same minutes cannot support a CCM code and another billed code.
- A new patient, or one not seen in the previous year, needs an initiating visit where CCM is discussed.
- Consent has to be in the chart before the first claim, and it can be verbal.
- Only one practitioner can bill CCM for a patient in a calendar month, and CMS prohibits several concurrent services in that month.
A CCM claim has to prove three things before it proves anything clinical: the patient qualified, the time was logged, and the plan reached the patient.OIG traced most CCM overpayments to duplicate and overlapping billing, not to a clinical judgment about the patient.
Two OIG audits of this service found the same pattern, and neither needed a clinical disagreement to call the money an overpayment. The rules below come from the Medicare Learning Network booklet on chronic care management, the CMS billing FAQs for the service, and the manual instructions CMS issued for health centers. Read them as one workflow: a claim that satisfies four of the five elements fails on the fifth.
Patient Eligibility and Who May Bill
The patient test comes from the code descriptor rather than from a payer policy. The patient needs two or more chronic conditions, those conditions must be expected to last at least 12 months or until death, and they must place the patient at significant risk of death, acute exacerbation or decompensation, or functional decline. CMS lists diabetes, hypertension, heart failure, COPD, depression, and autism spectrum disorders among its examples, so a behavioral health diagnosis can supply half of the two-condition test on a primary care panel.
Who may bill is narrower than who may do the work. Physicians, nurse practitioners, physician assistants, certified nurse-midwives and clinical nurse specialists bill CCM. Clinical psychologists, podiatrists and dentists cannot bill it, though the practitioner who does may consult them and coordinate their care. Pharmacists, social workers, registered dietitians and psychologists who cannot bill directly can still perform the work as clinical staff under general supervision, as long as the incident to requirements in 42 CFR 410.26 are satisfied.
The pattern that stalls these programs is administrative. The coordination happens by phone and in the portal, and the chart records none of it. Teams that run internal medicine revenue cycle management build the time record into the workflow that produces the charge.
CCM describes non-face-to-face care management. The billing practitioner does not have to be present while the work happens, and the work does not have to happen in the office. An activity inside the CCM scope of service still counts when it happens face to face, provided those minutes are not counted toward another billed code.
The Code Set and the Minutes Behind It
CCM codes sit on two axes: who spent the time, and how much of it, per calendar month.
| Code | Who spends the time | Threshold in the calendar month |
|---|---|---|
| 99490 | Clinical staff, directed by the practitioner | First 20 minutes |
| 99439 | Add-on listed with 99490 | Each additional 20 minutes |
| 99491 | The billing practitioner personally | First 30 minutes |
| 99437 | Add-on listed with 99491 | Each additional 30 minutes |
| 99487 | Clinical staff, complex CCM | First 60 minutes |
| 99489 | Add-on listed with 99487 | Each additional 30 minutes |
| G0506 | The billing practitioner, at initiation | Once, with the initiating visit |
Time ownership differs by code. For 99490, 99439, 99487 and 99489, minutes may come from clinical staff or from the billing practitioner, and practitioner time counts toward the clinical staff threshold when it is not reported as 99491. For 99491 and 99437, only the practitioner’s own time counts.
Add-on codes ride with their base code: 99439 with 99490, and 99489 with 99487. A month that falls short of the base threshold is not a month for the add-on alone, and one Medicare contractor has published an add-on billed without its primary code as a billing requirement error.
Minutes billed under one code cannot support another. When a single activity serves several patients, CMS splits the time across them: 30 minutes spent on three patients is 10 countable minutes for each. General supervision covers 99487, 99489, 99490 and 99439, so the billing practitioner sets the direction without being in the building.
The Initiating Visit and the Consent Behind the First Claim
A new patient, or a patient not seen by the billing practitioner in the previous year, needs an initiating visit before CCM can start. The visit has to be a comprehensive face-to-face evaluation and management visit, an annual wellness visit, or an initial preventive physical exam, and CCM has to be discussed during it. Levels 2 through 5 office visits qualify, and so does the face-to-face visit inside a transitional care management service. A thorough visit where CCM never came up cannot serve as the initiating visit.
- The initiating visit is separately billable. It is not part of the CCM service. When the practitioner personally provides extensive assessment and care planning beyond the usual effort of that visit, the work is reported once with HCPCS G0506 alongside it.
- Consent is a separate requirement. It does not have to be obtained at the initiating visit, but it must be documented before the first CCM claim.
Consent may be written or verbal, and the record has to show what the patient was told: that the service is available, that cost sharing may apply, that only one practitioner can furnish and bill CCM in a calendar month, and that the patient may stop the service at any time, effective at the end of the month. The consent holds until the patient moves to a different CCM practitioner.
Consent is a condition of payment. Without a documented consent the practice cannot bill Medicare or the patient, and an advance beneficiary notice is not the remedy, because CMS treats CCM as a covered and reasonable service. Unbilled work is treated as included in the payment for the face-to-face visit.
The Care Plan, 24/7 Access, and the Rest of the Scope of Service
The care plan is what a reviewer opens first. It has to be patient-centered, electronic, and built from an assessment of physical, mental, cognitive, psychosocial, functional and environmental needs, plus an inventory of the patient’s resources and supports. CMS presents the elements below as typical rather than as a rigid list, and a reviewer still reads them as the definition of a plan. The plan is made available promptly inside and outside the practice.
- Problem list.
- Expected outcome and prognosis.
- Measurable treatment goals.
- Cognitive and functional assessment.
- Symptom management.
- Planned interventions.
- Medical management.
- Environmental evaluation.
- Caregiver assessment.
- Interaction and coordination with outside resources and practitioners.
Three obligations travel with the code. The practice gives patients 24/7 access to a practitioner or clinical staff member for urgent needs, by phone and by secure messaging or another asynchronous method. A named care team member stays in contact between visits. Care transitions count as CCM work, including referrals, follow up after a discharge, and continuity-of-care documents shared promptly with other practitioners. Patient health information is recorded in certified electronic health record technology.
Panels with heavy medication loads gain the most, because reconciling the medication list and reviewing interactions sit inside the scope of service. A geriatrics revenue cycle management workflow that reconciles medications between visits has already done the work CCM pays for.
What Cannot Be Billed in the Same Month
The concurrent billing rules are narrow and worth memorizing, because both OIG audits of this service traced most of the overpayments to a month billed twice or to a service that overlapped with another care management code.
- One practitioner per calendar month. A second claim for the same patient in the same month is an overpayment, even when both practices furnished real services.
- Complex and non-complex CCM do not mix. 99487 and 99489 cannot be reported in the same month as 99490, 99439, 99491 or 99437.
- Home health and hospice supervision are excluded. HCPCS G0181 and G0182, and the ESRD codes 90951 through 90970, cannot share a service period with CCM.
- Complex CCM and prolonged office visits do not share a month.
- Remote monitoring is either or. RPM or RTM can run alongside CCM, not both at once.
- PCM by the same practitioner is excluded. A primary care practitioner and a specialist can each bill one of the two services in a month when the conditions addressed are different, and two care plans then exist.
- Transitional care management is allowed. 99495 and 99496 can be reported during a CCM service period, provided the minutes are not counted twice.
Behavioral health practices report a related pair of codes. General behavioral health integration, 99484, covers at least 20 minutes of clinical staff time per calendar month for a patient with a behavioral health condition, and CMS allows it in the same month as CCM when each service’s requirements are met and no minute is shared.
Effective January 1, 2026, RHCs and FQHCs bill care coordination services established under the Physician Fee Schedule as designated care management services, so the same CCM codes appear on a health center claim. The individual codes replaced the bundled HCPCS code G0511. Coinsurance is 20 percent of the lesser of submitted charges or the national non-facility PFS rate.
Where the Audits Land
OIG reviewed 8,061,572 paid CCM claims for calendar years 2017 and 2018 and found 50,192 that did not meet federal requirements, producing $1,918,278 in overpayments. The largest category was duplicate billing: 38,447 claims worth $1,427,930 where a non-complex or complex CCM service was billed more than once for the same beneficiary in the same service period. Another 10,882 claims, worth $438,262, were billed alongside an overlapping care management service. Beneficiaries paid up to $540,680 of that money in cost sharing.
Contractor reviews fail on documentation more often than on coding. CERT error findings for one Medicare Administrative Contractor, covering errors assessed in the quarter that ended June 2025, listed insufficient documentation as 50 percent of all errors, with CCM records missing the care plan, missing evidence that the plan reached the patient, and missing support for the time claimed. The same report listed 99439 billed without its primary code as a billing requirement error.
Enforcement has moved past claim edits. In June 2024 a chronic care provider paid $14,902,000 to resolve allegations covering 2015 through 2019 that included 99490 claims that did not support the level of service billed, and entered a five-year corporate integrity agreement. OIG opened another audit of CCM payments on March 16, 2026, focused on whether the patients billed under the code meet the multiple chronic conditions requirement.
The Monthly Workflow That Makes the Claim Defensible
Run these six steps every month, before the claim leaves the practice.
Screen the Medicare panel for two documented chronic conditions, a documented statement of risk, and a visit in the past 12 months. Book an initiating visit for anyone not seen.
Every activity gets a date, a duration, the staff member’s name and a short description of the work. A single line reading 20 minutes of CCM gives a reviewer nothing to verify.
Check that consent is in the chart with the date and method recorded, and that the initiating visit note says CCM was discussed. Both checks belong before the first claim.
Update the plan when the medication list, the goals or the care team changes, and record that the patient or caregiver received a copy.
One practitioner, no complex and non-complex mix, no prohibited code in the same service period, and no minutes counted on another claim.
Score five completed months against the time log and the care plan as a reviewer would, then count the misses by element instead of by clinician.
The review is where the program pays for itself: a coder who finds the missing care plan before the charge drops has a note the clinician can still amend.
Chronic care management billing questions
The base code for clinical staff time, 99490, needs at least 20 minutes in the calendar month, and add-on 99439 covers each additional 20 minutes. Practitioner time works on its own pair: 99491 for the first 30 minutes and 99437 for each additional 30. Complex CCM starts at 60 minutes of clinical staff time with 99487. Minutes do not carry into the next month.
Yes. CCM and evaluation and management visits can be reported in the same month and even on the same day, as long as the minutes are not counted twice. The office visit stands on its own documentation and its own medical decision making. CCM pays for the coordination around the visit, not for the visit itself.
Yes. The Part B deductible and coinsurance apply, because CCM is not one of the preventive services with cost sharing waived. Medigap policies pay the coinsurance on a covered service. CMS also states that Medicaid is responsible for the cost sharing of most dual eligible patients, who are Qualified Medicare Beneficiaries, even when a state plan does not cover the service.
The practice cannot bill Medicare or the patient for that month, and an advance beneficiary notice will not rescue it, because CMS considers CCM a covered service. The work is treated as included in the payment for the face-to-face visit that was billed. Re-verify consent whenever a patient moves to a new CCM practitioner.
Clinical staff can furnish the work under the general supervision of the billing practitioner, subject to state licensure and scope of practice and to the incident to rules at 42 CFR 410.26. The billing practitioner keeps the oversight, collaboration and reassessment, and that part cannot be delegated. Complex CCM also requires the practitioner’s own moderate to high complexity decision making.
Each entry needs a date, a duration, the name of the person who did the work, and a description of the activity. A monthly total with no detail behind it does not support the claim. Contractor findings cite missing time documentation as a recurring error, so log the calls, medication reviews, care coordination and transitions as they happen.
Not on a Medicare claim. The CMS booklet and these codes describe Original Medicare, and an Advantage plan pays for care management through its own contract and provider manual, which may or may not use the same codes. Read the plan’s policy before enrolling a patient. In either setting, only one practitioner can bill for a patient in a calendar month.
The bottom line
CCM pays for coordination most practices already perform, and the claim stands or falls on records rather than on clinical skill. The five elements are a patient test, an initiating visit, a documented consent, a live care plan, and a time log that adds up. Build them into the monthly routine and the code becomes one of the most defensible services in the practice.
