G0022
Description, Billing Rules, and Use Cases

HCPCS G0022 is an add-on billing code used to report each additional 30 minutes of Community Health Integration (CHI) services after the first 60 minutes (which are reported under G0019) in a calendar month.

These services are provided by certified auxiliary personnel under general supervision and must directly address patient-specific barriers related to social determinants of health (SDOH).

What is HCPCS Code G0022?

G0022 allows providers to bill for extended CHI services that go beyond the first 60 minutes captured under G0019. It represents each subsequent 30-minute increment, enabling more time to support patients facing significant non-clinical challenges that affect their care.

Covered service elements include:

Ongoing navigation of health systems and access barriers

Continued emotional and social support

Assistance in applying for benefits, housing, or food assistance

Coaching and behavior change strategies

Coordination with community-based organizations and care teams

Use of lived experience or culturally matched navigators, when applicable

G0022 must be billed in conjunction with G0019 and may be stacked if total CHI time exceeds 90 minutes in a calendar month.

G0022 Billing Requirements and Eligibility

G0022 is an add-on code and can only be billed in conjunction with G0019. It represents each additional 30 minutes of Community Health Integration (CHI) services performed within the same calendar month after the initial 60 minutes.

Patient Eligibility Criteria

To qualify for G0022:

The patient must have already met the criteria for G0019, including:
- One or more clinical conditions requiring treatment
- One or more documented SDOH barriers (e.g., food insecurity, housing instability, transportation issues)
- An initiating visit (e.g., E/M, AWV, behavioral health assessment) occurring before or on the same date as CHI services

Supervision and Who Can Provide the Service

Services must be personally provided by auxiliary personnel (e.g., CHWs, peer navigators, health educators)
All services are delivered under general supervision of a Medicare-enrolled practitioner
The supervising provider must:
- Be a physician, nurse practitioner, physician assistant, or CNS
- Be available for consult but not required to be onsite during service delivery
- Remain responsible for billing and care oversight

Documentation and Time Tracking Requirements

G0022 represents each additional 30-minute increment of CHI services after the first 60 minutes billed under G0019
You must document:
- A clear breakdown of time spent beyond the 60-minute baseline
- Specific services rendered during the additional time (e.g., follow-up coaching, second visit coordination, resource navigation)
- How services align with the patient’s care plan or treatment goals

G0022 cannot be billed as a standalone code and may only be submitted if at least 90 total minutes of CHI time are delivered in the same month.

G0022 Billing Documentation Checklist

To bill G0022, the following documentation must be present in the patient’s medical record:

Link to G0019 in the same calendar month:
- G0022 may only be billed if G0019 was also reported
- Ensure both codes appear on the same claim or are tied to the same billing month
Total CHI time meets threshold for add-on billing:
- Cumulative service time must be ≥90 minutes
- Each unit of G0022 represents an additional 30 minutes beyond the first 60
- Include a time log or attestation showing all applicable CHI activity
Detailed description of extended service components:
- Document what occurred during the additional time (e.g., coaching sessions, follow-up outreach, secondary barrier resolution)
- Activities must build on the care coordination or resource navigation initiated under G0019
- Describe any new SDOH issues that emerged and how they were addressed
Auxiliary personnel and supervision:
- Name, title, and credentials of the staff member(s) delivering the service
- Statement that services were delivered under general supervision of a billing practitioner
- Supervising practitioner’s name and role noted in the record
Care plan alignment and care team communication:
- Services must be tied to patient care goals or follow-up from the initiating visit
- Document any escalation to the supervising provider or new care plan updates

G0022 Time Thresholds and Code Combinations

G0019 is billed for the first 60 minutes of Community Health Integration (CHI) services delivered in a calendar month. Additional time may be reported using G0022, but only when all thresholds and documentation are met.

Key Reminders:

G0019 must always be billed first — G0022 is not a standalone code
Each unit of G0022 represents a full 30-minute block
Cumulative time should be clearly documented and tracked
All time must be personally performed by qualified auxiliary staff under general supervision

When to Use G0022:
Common Scenarios and Use Cases

G0022 should be billed when Community Health Integration (CHI) services exceed 90 minutes in a calendar month. Each additional 30-minute block — after the first 60 minutes reported under G0019 — must be medically relevant, documented, and tied to care plan goals.

Here are examples of how G0022 is used in practice:

Extended Navigation for Multi-Barrier Patient With COPD
A community health worker under NP supervision:
- Coordinates ongoing transportation for pulmonary rehab
- Helps patient apply for Medicaid retroactive coverage
- Organizes a housing support application and food pantry enrollment
- Reassesses progress with new goals added to care plan
  Total qualifying time: 122 minutes
  Billing: G0019 + G0022 x2

Long-Term Coaching and Benefits Reinstatement
A bilingual peer navigator under PA supervision:
- Spends multiple sessions coaching a patient newly diagnosed with major depression
- Supports them in reinstating SSDI and Medicaid after recent housing transition
- Escalates a food access gap to social work and follows up with pharmacy on copay waivers
  Total qualifying time: 147 minutes
  Billing: G0019 + G0022 x2

Postpartum Resource Coordination and Social Isolation Support
A lay health educator with lived experience under MD supervision:
- Connects a new mother with community doulas and infant nutrition programs
- Provides phone-based check-ins to encourage postpartum follow-up compliance
- Delivers culturally matched mental health referral resources
- Builds rapport to address long-standing mistrust in healthcare
  Total qualifying time: 174 minutes
  Billing: G0019 + G0022 x3

Common G0022 Billing Mistakes
(and How to Avoid Them)

As an add-on code, G0022 introduces specific billing vulnerabilities — particularly around stacking, supervision, and cumulative time tracking.

❌ Billing G0022 Without G0019
G0022 is an add-on code and may not be billed on its own. It must follow a G0019 claim during the same calendar month. Submitting G0022 without G0019 will result in denial.
❌ Under-documenting Total Time
You must log at least 90 total minutes of CHI service in the billing month before billing the first unit of G0022. Each additional unit requires another full 30 minutes. Partial time cannot be rounded up.
❌ Vague or Repetitive Documentation
Only direct CHI service time counts — not idle time, administrative paperwork, or waiting periods. Be especially cautious when multiple auxiliary staff contribute across days.
❌ Missing Supervision Details
Even when stacked, each unit of G0022 must still meet the general supervision requirement. Documentation should include the supervising practitioner’s name and role.
