G0022 cpt code serves as an ad-on code for the community health integration services. It includes 30 minutes of healthcare services in a calendar month. The chi add-on billing code is assigned after G0019 that covers the initial 60 minutes of the patient treatment.
Community health integration services are provided by an auxiliary personnel under the expert supervision of a qualified physician. CHI services aim to address the patient’s inabilities towards social determinants of health.
CMS reported that the Accountable Health Communities (AHC) Model screened more than 1.1 million Medicare and Medicaid beneficiaries and generated over $200 million in net savings.
Understanding G0022 cpt code
CPT code G0022 enables the healthcare provider to extend the duration of community health integration service for an additional 30 minutes. This additional time helps patients get treatment related to the non-clinical challenges they face every day.
Element of CHI services include:
- Continues moral supposition from the providers.
- Help in applying for basic necessities like food, housing and transportation.
- Coaching about behavioural changing strategies.
- On-going support with healthcare systems.
Who May Provide CHI Services?
Trained Auxiliary Personnel: CHI services can involve expert auxiliary personnel, including community health workers. Their work should support the patient’s needs and treatment goals.
Supporting Patient Needs: Imagine a patient has difficulty getting transportation and accessing food resources. A community health worker may help identify local resources, coordinate referrals, and support follow-up. The time spent on eligible CHI activities can be tracked across the month.
Meeting CHI Requirements: The service must meet the applicable CHI requirements. Simply making a routine administrative call does not make the time billable.
When Should G0022 Be Billed?
The ad-on code is not designed to replace G0019 or stand alone. The first 60 minutes are reported with G0019, while qualifying additional CHI time may be reported with G0022.
A simple example makes the structure easier to understand:
- 60 minutes of eligible CHI time → G0019
- 90 minutes of eligible CHI time → G0019 + one G0022 unit
- 120 minutes of eligible CHI time → G0019 + two G0022 units
The exact billing and time rules can depend on the payer and applicable policy. Medicare and Medicaid programs may also publish additional guidance. Therefore, practices should verify current payer requirements before submitting claims.
G0022 CPT Code Time Calculation
G0022 represents an additional 30-minute service period. Practices should track qualifying CHI work throughout the calendar month instead of treating every phone call as a separate billing event.
Example
Suppose a community health worker spends 20 minutes helping a patient arrange transportation. Later, the worker spends another 25 minutes coordinating a community referral. If those activities qualify, the practice should maintain clear records of the time and work performed.
G0022 vs G0019
Understanding the two codes is essential because they work together. G0019 represents the first 60 minutes of qualifying CHI services in a calendar month, while the G0022 CPT code addresses later qualifying time. G0022 represents each additional 30 minutes after that initial service period.
| Code | Basic role | Time |
| G0019 | Initial CHI service | 60 minutes |
| G0022 | Additional CHI service | Each additional 30 minutes |
The distinction is simple: G0019 starts the monthly CHI service, while the G0022 CPT code captures qualifying additional time.
AAPC lists the official long descriptor for G0022 as Community Health Integration services, each additional 30 minutes per calendar month, listed separately in addition to G0019.
Community Health Integration Additional Time
Understanding community health integration additional time helps billing teams decide when an extra unit may be appropriate.
What Services Can Support Additional Time?
The code may apply when additional CHI work continues to address documented patient needs. Common activities can include:
- Helping patients access appropriate health or community services
- Coordinating with community-based organizations
- Supporting care coordination
- Helping patients follow a treatment plan
- Providing social or emotional support
- Promoting patient self-advocacy
- Supporting behavior change related to treatment goals
- Using lived experience when applicable
The work should connect to the patient’s identified needs and treatment goals. A practice should avoid adding unrelated administrative time to the CHI total.
The AAFP notes that CHI services can include person-centered planning, health-system navigation, access to community resources, care coordination, and patient self-advocacy.
CHI Add-On Billing Requirements
For chi add-on billing, the most important rule is to treat G0022 as an extension of the initial CHI service.
The initiating visit is also important. Before CHI services are furnished, the applicable requirements must be met, including identification of unmet social needs that significantly affect the provider’s ability to diagnose or treat the patient’s condition.
The medical record should clearly support why the G0022 CPT code services were needed. It should also show what work was performed and how that work relates to the patient’s needs.
A strong documentation record may include:
- The patient’s identified social needs
- The relevant treatment plan
- Date of each service
- Start and end times or total duration
- Activities performed
- Resources or referrals addressed
- Patient engagement or response
- The staff member providing the service
- Required supervision or practitioner involvement
Washington’s current CHW billing guide states that G0022 must be submitted with G0019 on the same claim and should include documentation supporting the need for additional time.
Common G0022 Billing Mistakes
Billing Without G0019: One common mistake is billing G0022 without G0019. Because G0022 is an add-on code, practices should not treat it as a standalone service.
Incorrect Time Tracking: Another mistake is failing to combine qualifying time correctly across the month. CHI services may occur through several contacts. Good time tracking helps the billing team determine whether additional units are supported.
Weak Documentation: A third problem is weak documentation. A note that only says “followed up with patient” may not explain what CHI work occurred.
Unclear Service Details: Instead, documentation should describe the service. For example, it could state that the worker contacted a transportation resource, discussed available options with the patient, and coordinated follow-up related to the patient’s documented care needs.
Assuming All Work Is Billable: Practices should also avoid assuming that every activity performed by a community health worker is automatically billable. The activity must meet the applicable CHI requirements.
How to Document G0022 CPT Code Time
A simple G0022 CPT code documentation workflow can reduce billing errors.
First, identify the patient’s qualifying needs and treatment goals. Next, record each CHI activity as it happens. Include the date, duration, and purpose of the work.
Then, maintain a monthly running total. This makes it easier to identify when the initial 60 minutes have been met and when additional units may be supported.
Before claim submission, the billing team should compare the documented time with the units reported. The claim should also meet the payer’s specific rules.
G0022 CPT Code Payer Considerations
Medicare established G0019 and G0022 as CHI codes for services addressing health-related social needs. Federal guidance describes G0022 as additional CHI time following the initial G0019 service.
However, payer policies can differ. Medicaid programs may add their own documentation, authorization, billing, or time requirements. For example, California Medi-Cal requires an initiating visit and treatment plan before G0019 and G0022 billing.
Because payment policies can change, billing teams should verify the current Medicare Administrative Contractor or Medicaid payer guidance before relying on a specific rate or billing rule.
Final Takeaway
The G0022 CPT code helps practices report qualifying additional CHI service time after the initial G0019 service. It represents each additional 30 minutes in a calendar month and is reported separately with G0019.
Accurate time tracking, strong documentation, and payer-specific checks are the foundation of compliant CHI billing. When staff understand the difference between the initial service and additional time, claims become easier to prepare and review.
