Updated for 2026. HCPCS G0506 is a Medicare add-on code related to the initiation of Chronic Care Management (CCM). It recognizes situations where the billing practitioner personally performs extensive assessment and care planning beyond the usual work of the separately billable CCM initiating visit.
G0506 is different from monthly CCM codes such as 99490, 99491, 99487, and their add-on codes. It is tied to the CCM initiating visit rather than routine monthly care-management time.

What Is HCPCS G0506?
CMS describes G0506 as an add-on service for situations in which the billing practitioner personally provides extensive assessment and care planning that goes beyond the usual effort included in the initiating visit and the CCM service itself.
In practical terms, it recognizes additional practitioner work necessary to thoroughly assess a complex patient and establish the patient's comprehensive chronic-care plan when that work is substantially beyond what would ordinarily be expected during the initiating visit.
When Is a CCM Initiating Visit Required?
CMS requires an initiating visit before CCM services begin for:
- New patients
- Patients who have not been seen by the billing practitioner within the previous year
CMS states that this initiating visit can occur during an appropriate:
- Comprehensive face-to-face Evaluation and Management visit
- Annual Wellness Visit (AWV)
- Initial Preventive Physical Examination (IPPE)
The initiating visit itself is separate from monthly CCM and may be separately billed when applicable requirements are met.
When Can G0506 Be Added?
CMS states that if the billing practitioner personally provides extensive assessment and care planning beyond the usual effort described by the initiating visit and CCM codes, HCPCS G0506 may also be billed once as part of the initiating visit.
This means G0506 should not be added automatically to every patient who starts CCM.
The documentation should support why the patient's assessment and care-planning needs required work beyond the normal initiating visit.
Who Must Perform G0506?
The additional assessment and care-planning work represented by G0506 must be performed personally by the billing practitioner.
It should not be supported solely by clinical-staff work.
For example, an RN may gather information and support the CCM workflow, but G0506 specifically recognizes the additional extensive assessment and care-planning work personally performed by the billing practitioner.
What Does Extensive Assessment Mean?
The exact assessment will depend on the patient's needs. CMS describes comprehensive care planning activities that may involve:
- A thorough physical examination
- A broad and systematic differential diagnosis
- Review of previous laboratory evaluations
- Review of treatment history
- Assessment of multiple chronic conditions
- Evaluation of functional needs
- Assessment of cognitive needs
- Review of psychosocial circumstances
- Evaluation of environmental factors
- Assessment of caregiver support
G0506 should represent extensive work beyond what would ordinarily be included in the initiating visit.
What Does CCM Care Planning Include?
A comprehensive CCM care plan may include:
- Problem list
- Expected outcomes and prognosis
- Measurable treatment goals
- Symptom-management strategy
- Planned clinical interventions
- Medication management
- Cognitive and functional assessment
- Environmental evaluation
- Caregiver assessment
- Coordination with outside practitioners
- Community-resource coordination
- Periodic review and revision
The care plan should be individualized to the patient's actual medical, functional, psychosocial, and care-coordination needs.
Example of When G0506 May Be Appropriate
Consider a new Medicare patient with:
- Heart failure
- Type 2 diabetes
- Chronic kidney disease
- COPD
- Multiple medications
- Recent hospitalizations
- Several specialists
- Functional limitations
- Caregiver involvement
During the qualifying initiating visit, the practitioner performs the normal visit work and then personally completes additional extensive assessment and care planning.
The practitioner reviews prior hospital records, reconciles a complicated medication list, evaluates competing specialist recommendations, assesses functional and caregiver needs, establishes detailed treatment goals, and develops a comprehensive CCM care plan.
If that work is beyond the usual effort associated with the initiating visit and all applicable requirements are satisfied, G0506 may be considered in addition to the qualifying initiating-visit code.
Example Where G0506 May Not Be Appropriate
A patient receives an initiating visit before beginning CCM. The practitioner performs the usual evaluation, discusses CCM, and establishes a routine care plan without extensive additional assessment or care-planning work.
The fact that the patient enrolled in CCM does not automatically support G0506.
The record should demonstrate the additional extensive practitioner work represented by the code.
G0506 Is Not a Monthly CCM Code
G0506 should not be confused with the monthly CCM code families.

G0506 addresses the initial extensive assessment and care-planning work, while the other codes generally represent ongoing monthly care-management services.
Can G0506 Be Billed Every Month?
No. CMS describes G0506 as an add-on that may be billed once as part of the CCM initiating visit when the billing practitioner personally performs the required extensive assessment and care planning.
It is not a recurring monthly CCM add-on code.
Can G0506 Automatically Be Billed With an Annual Wellness Visit?
No. An Annual Wellness Visit may serve as a CCM initiating visit when applicable requirements are met, but that alone does not establish eligibility for G0506.
The practitioner must also personally perform extensive assessment and CCM care planning beyond the usual effort represented by the initiating visit.
Can G0506 Be Added to an IPPE?
An Initial Preventive Physical Examination may serve as a qualifying CCM initiating visit. If the practitioner personally performs extensive additional assessment and care planning beyond the usual IPPE and CCM work, G0506 may potentially be considered when all requirements are met.
Can G0506 Be Added to an E/M Visit?
A qualifying comprehensive face-to-face E/M visit can serve as the CCM initiating visit.
G0506 may be considered when the practitioner personally performs extensive CCM assessment and care planning beyond the work ordinarily included in that separately billed E/M service.
Is the Initiating Visit Part of Monthly CCM?
No. CMS states that the face-to-face initiating visit is not itself part of the monthly CCM service and may be separately billed.
This distinction matters because G0506 is an add-on associated with the initiating visit rather than an additional unit of monthly CCM time.
G0506 Documentation Example
Example: During CCM initiating visit, physician personally performed extensive assessment and care planning beyond the usual E/M service. Reviewed recent hospitalization records, cardiology and nephrology recommendations, medication history, functional limitations, caregiver availability, transportation barriers, and chronic-condition risks. Established individualized comprehensive CCM care plan addressing CHF, diabetes, CKD, and COPD, including treatment goals, medication-management strategy, specialist coordination, patient self-management responsibilities, and planned follow-up.
This provides substantially more support than an entry stating only: CCM initiated; G0506 billed.
What Should G0506 Documentation Show?
Consider documenting:
- The qualifying initiating visit
- Why CCM is clinically appropriate
- The patient's qualifying chronic conditions
- The additional extensive assessment personally performed by the practitioner
- Records and treatment history reviewed
- Medication-management assessment
- Functional or cognitive assessment when relevant
- Psychosocial and environmental needs when relevant
- Caregiver needs when relevant
- Specialist and community-resource coordination needs
- Development of the comprehensive CCM care plan
- How the work exceeded the usual effort of the initiating visit
Patient Eligibility Still Matters
G0506 is associated with patients requiring CCM services, so the underlying CCM eligibility criteria remain important.
Medicare CCM generally applies when a patient has two or more chronic conditions that:
- Are expected to last at least 12 months or until the patient's death
- Place the patient at significant risk of death, acute exacerbation or decompensation, or functional decline
Practices should document why the patient qualifies rather than relying only on a diagnosis count.
CCM Consent
Patient consent remains part of the CCM enrollment process.
CMS permits written or verbal consent when properly documented.
The patient should understand:
- The availability and nature of CCM services
- Possible cost sharing
- That only one practitioner may furnish and bill CCM during a calendar month
- That the patient can stop CCM services
G0506 vs CPT 99491
G0506 and CPT 99491 both involve practitioner work, but they serve different purposes.

G0506 vs CPT 99487
G0506 should also not be confused with Complex CCM.
CPT 99487 represents an ongoing monthly Complex CCM service that includes the required clinical-staff time and moderate- or high-complexity medical decision-making.
G0506 instead recognizes extensive initial assessment and care planning personally performed by the practitioner in association with a qualifying CCM initiating visit.
Common G0506 Billing Mistakes
1. Adding G0506 to Every CCM Enrollment
The code is intended for extensive assessment and care planning beyond the usual initiating-visit work. Enrollment alone does not support the code.
2. Treating G0506 as a Monthly Code
CMS describes G0506 as a one-time add-on associated with the initiating visit when requirements are satisfied.
3. Using Clinical-Staff Work to Support the Code
The extensive assessment and care planning represented by G0506 must be personally performed by the billing practitioner.
4. Missing the Initiating Visit
G0506 is associated with the CCM initiating visit. It is not an independent monthly care-management service.
5. Failing to Document Work Beyond the Usual Visit
The medical record should explain what extensive assessment and care planning occurred beyond the normal work of the initiating visit.
6. Confusing G0506 With 99491
99491 represents ongoing monthly practitioner CCM time, while G0506 relates to extensive assessment and care planning during CCM initiation.

How ChronicSync Can Help
Starting a CCM patient requires more than adding the patient to a monthly call list. Practices need a clear enrollment workflow for eligibility, consent, comprehensive assessment, care planning, ongoing activities, and billing documentation.
ChronicSync helps care teams organize chronic-care workflows, maintain structured patient information, document care plans, and create clearer visibility from enrollment through ongoing monthly management.
A structured workflow can help teams distinguish the initiating phase of CCM from recurring monthly services and maintain clearer supporting documentation.
