Updated for 2026. CPT 99490 is one of the primary Medicare Chronic Care Management (CCM) codes used by practices caring for patients with multiple chronic conditions.
CMS identifies CPT 99490 as the first 20 minutes of qualifying Chronic Care Management services performed by clinical staff under the direction of a physician or other qualified healthcare professional during a calendar month.
However, reaching a time threshold alone does not make a service billable. The patient must meet Medicare CCM eligibility requirements, consent must be documented, a comprehensive care plan must be maintained, and the recorded activity must represent qualifying chronic-care management.

What Is CPT 99490?
CPT 99490 represents non-face-to-face and other qualifying care-management work performed throughout a calendar month for an eligible patient with multiple chronic conditions.
The service supports ongoing coordination between regular office visits and may involve:
- Medication management
- Care-plan monitoring and revision
- Patient and caregiver communication
- Specialist coordination
- Referral follow-up
- Care-transition support
- Review of clinically relevant patient information
- Coordination with community or home-based resources
- Addressing barriers affecting chronic-condition management
Who Qualifies for Medicare CCM?
CMS covers CCM for patients with two or more chronic conditions that are expected to last at least 12 months, or until the patient's death.
The chronic conditions must also place the patient at significant risk of:
- Death
- Acute exacerbation
- Decompensation
- Functional decline
Eligibility should be based on the patient's documented clinical situation rather than diagnosis count alone.
Examples of Chronic Conditions
CMS identifies many conditions that may be relevant to CCM eligibility, including:
- Diabetes
- Hypertension
- Heart disease
- Chronic obstructive pulmonary disease
- Asthma
- Arthritis
- Atrial fibrillation
- Alzheimer's disease and related dementia
- Chronic kidney disease
- Depression
The presence of two diagnoses alone does not automatically establish eligibility. The conditions must meet Medicare's duration and risk requirements.
How Much Time Is Required for CPT 99490?
CMS's current CCM guidance lists CPT 99490 as the first 20 minutes of qualifying clinical-staff CCM during a calendar month.
If additional qualifying time is supported, CPT 99439 may be considered for additional 20-minute periods according to current coding and payer rules.
CodeTime99490First 20 minutes99439Each additional 20 minutes
Who Can Perform CPT 99490 Services?
CPT 99490 is structured around qualifying services performed by clinical staff under the direction of the billing physician or other qualified healthcare professional.
Depending on state law, staff qualifications, scope-of-practice requirements, and organizational policies, a CCM team may include appropriately qualified:
- Registered nurses
- Licensed practical or vocational nurses
- Medical assistants when applicable requirements are satisfied
- Other qualifying clinical staff
- Contracted clinical staff when Medicare requirements are met
CMS assigns applicable CCM clinical-staff services to general supervision, meaning the billing practitioner does not need to be physically present for every qualifying activity but remains responsible for overall direction and involvement.
Can Physician Time Count Toward CPT 99490?
Yes. CMS states that CPT 99490, 99439, 99487, and 99489 can include qualifying time spent directly by the billing practitioner as well as clinical staff.
However, practitioner time counted toward CPT 99490 cannot also be used to report practitioner-only CCM under CPT 99491.
This is why practices should track staff and practitioner activity separately even when both contribute to the patient's CCM program.
What Activities Can Count Toward CPT 99490?
Qualifying activities should directly support management of the patient's chronic conditions and comprehensive care plan.
Medication Management
- Medication reconciliation
- Reviewing adherence concerns
- Following up on medication changes
- Communicating clinically relevant medication concerns to the practitioner
Care Plan Management
- Reviewing treatment goals
- Updating interventions
- Documenting clinically relevant changes
- Monitoring progress toward patient goals
Patient and Caregiver Communication
- Reviewing symptoms
- Discussing adherence to the established treatment plan
- Identifying barriers to care
- Providing education related to the care plan
Care Coordination
- Coordinating with specialists
- Managing clinically relevant referrals
- Communicating with home-health providers
- Coordinating community resources
- Following up after care transitions

If the patient and documented services satisfy all other applicable Medicare requirements, the billing team may evaluate whether CPT 99490 is supported.
Patient Consent for CPT 99490
Medicare requires informed patient consent before CCM begins.
CMS allows consent to be verbal or written, but it must be documented in the medical record.
Patients should be informed about:
- The availability and nature of CCM services
- Possible cost-sharing responsibilities
- The fact that only one practitioner may furnish and bill CCM during a calendar month
- The patient's right to stop CCM services
Example Consent Documentation
Patient informed about Chronic Care Management, possible Medicare cost sharing, the one-practitioner monthly billing limitation, and right to discontinue services. Patient verbalized understanding and provided verbal consent.
Is an Initiating Visit Required?
CMS requires an initiating visit before CCM begins for:
- New patients
- Patients who have not been seen by the billing practitioner within the previous year
CMS states that the initiating visit may occur during an appropriate:
- Evaluation and Management visit
- Annual Wellness Visit
- Initial Preventive Physical Examination
The initiating visit is separate from the monthly CCM service.
Comprehensive Care Plan Requirements
CMS identifies an electronic, patient-centered comprehensive care plan as a core CCM component.
A comprehensive care plan may include:
- Problem list
- Expected outcomes and prognosis
- Measurable treatment goals
- Cognitive and functional assessment
- Symptom management
- Planned interventions
- Medication management
- Environmental evaluation
- Caregiver assessment
- Coordination with outside practitioners and resources
- Periodic review
- Revision and monitoring when necessary
The care plan should reflect the individual patient's conditions, goals, barriers, treatment needs, and available resources.
Does the Care Plan Need to Be Updated?
Yes, when clinically appropriate. CMS describes CCM as including creation, revision, and monitoring of the comprehensive care plan.
Updates may be appropriate after:
- Medication changes
- Hospitalization
- Emergency-department visits
- New diagnosis
- Changes in functional status
- New specialist recommendations
- Changes in caregiver support
- Changes in treatment goals
24/7 Access and Continuity of Care
CMS includes access and continuity among the service elements associated with CCM.
Practices should maintain an operational process that supports patient access for urgent care-management needs and continuity with a designated member of the care team.
This does not mean one individual staff member must personally answer every patient contact around the clock. The organization should have an appropriate system for access and continuity consistent with CMS requirements.
CPT 99490 Documentation Example
Example: RN care manager spent 22 qualifying minutes during the calendar month managing patient's diabetes, hypertension, and COPD. Reviewed medication adherence, discussed home blood-pressure readings, identified missed medication doses, coordinated pulmonology follow-up, updated comprehensive care plan, and escalated persistent symptoms to supervising practitioner.
This documentation gives a reviewer information about the patient, activity, staff member, clinical purpose, and qualifying time.
What Should a CPT 99490 Note Include?
Consider documenting:
- Date of service
- Staff member
- Staff role
- Qualifying duration
- Chronic condition or care-plan issue addressed
- Activity performed
- Patient or caregiver communication
- Care coordination
- Relevant findings
- Action taken
- Escalation when appropriate
- Next follow-up
What Should Not Automatically Count Toward CCM Time?
Not every action involving a CCM patient should automatically be added to the monthly total.
Examples that should be carefully reviewed include:
- Waiting for a patient or provider response
- Routine clerical activity
- Unrelated administrative work
- Automated reminders without qualifying care-management activity
- Duplicated documentation
- Time already used to support another service when duplicate reporting is prohibited
What Is CPT 99439?
CPT 99439 is the add-on code associated with CPT 99490.
CMS identifies it as each additional 20 minutes of qualifying standard CCM services during the calendar month.
It cannot be reported as a stand-alone service. The record must support the applicable CPT 99490 base service first.

Feature9949099491Primary staff modelClinical staffPhysician/QHP personallyInitial time20 minutes30 minutesAdd-on9943999437Clinical staff time counts?YesNo
CMS states that CPT 99491 and 99437 should not be reported in the same calendar month as CPT 99490, 99439, 99487, or 99489 for the same patient.
CPT 99490 vs 99487
CPT 99490 represents standard CCM, while CPT 99487 represents Complex Chronic Care Management.
Feature9949099487CCM typeStandard CCMComplex CCMInitial time20 minutes60 minutesModerate/high complexity MDM required?No specific Complex CCM requirementYesAdd-on code9943999489
CMS does not allow standard and Complex CCM code families to be reported together for the same patient during the same calendar month.
Can CPT 99490 and RPM Be Billed Together?
CMS permits qualifying Remote Physiologic Monitoring or Remote Therapeutic Monitoring to be provided concurrently with CCM when the requirements of each service are independently satisfied.
The same time should not be counted twice across time-based services.
Practices should keep CCM and remote-monitoring activity clearly separated in their documentation.
Can CPT 99490 Be Billed During a TCM Period?
CMS allows qualifying CCM services to be reported during a Transitional Care Management period when the applicable requirements for each service are met.
Practices should avoid duplicate reporting of the same activity or time and verify the current coding rules for any service combination.
Common CPT 99490 Billing Mistakes
1. Billing Based Only on 20 Minutes
The time threshold does not replace patient eligibility, consent, care-plan, supervision, and other CCM requirements.
2. Missing Patient Consent
CMS requires informed consent before CCM is furnished and billed.
3. Using a Generic Care Plan
The comprehensive care plan should reflect the patient's actual chronic conditions, goals, interventions, and care needs.
4. Counting Purely Administrative Time
Not every administrative task should automatically be treated as qualifying care-management time.
5. Double Counting Time
The same minutes should not be used to support multiple time-based services when duplicate reporting is prohibited.
6. Billing 99439 Without 99490
CPT 99439 is an add-on code and requires the applicable base CCM service.
7. Mixing Standard and Complex CCM
CMS does not allow standard and Complex CCM code families for the same patient in the same calendar month.
8. Failing to Identify Who Performed the Service
Staff identity matters because Medicare's CCM codes distinguish clinical-staff services from services personally furnished by the billing practitioner.
