## **What is HCPCS Code G2211?** HCPCS code G2211 is an add-on code introduced by CMS to capture the increased complexity of particular office and outpatient evaluation and management (E/M) visits. It recognizes the additional work involved when a healthcare provider serves as the continuing focal point for all of a patient's needed health care services and medical care services over time or manages a patient's single serious condition. This code is billed in addition to base evaluation and management visit codes (CPT 99202-99205, 99211-99215) to reflect the longitudinal care nature of medical practice—such as in typical primary care physician office visits or specialty care for complex conditions, including those that require addressing behavioral health challenges or coordination with Medicaid services and other payers. The G2211 add-on code became payable starting January 1, 2024, after delays in implementation. Its purpose is to account for the extra time, care coordination, and clinical expertise required beyond standard visits, typically involving ongoing care related to chronic or severe health issues. It is not diagnosis-specific but focuses on the visit complexity inherent in comprehensive primary care responsibility. G2211 helps increase reimbursement for these higher-complexity visits, supporting long-term patient-provider relationships and continuing focal point care management under the Medicare Physician Fee Schedule.

## **HCPCS code G2211 documentation requirements** HCPCS code G2211 does not have specific additional documentation requirements mandated by CMS. CMS states that medical reviewers may use the existing medical record documentation to confirm the medical necessity of the visit and the patient care relationship for billing G2211. The documentation that supports G2211 typically includes the underlying office outpatient evaluation and management e-visit documentation, such as diagnoses, the provider’s assessment, medical plan of care, and any other health care services codes billed that demonstrate the longitudinal care relationship or ongoing preventive services for a serious or complex condition. CMS expects that the medical record or claims history should show that the provider is the continuing focal point for care or managing a patient's single, serious condition over time. There is also an expectation that the medical necessity for the visit is evident in the documentation. Providers should also follow documentation requirements related to the base evaluation and management visit and consult their Medicare Administrative Contractor for specific clarifications. No separate or new documentation elements beyond the existing coding processes are explicitly required for G2211.

## **G2211 billing requirements** The billing requirements for HCPCS code G2211 are as follows: - G2211 is an add-on code and must be billed in conjunction with a new or established patient office outpatient evaluation and management service (CPT codes 99202-99215). - It is used when the provider is the continuing focal point for all of the patient's health care or is providing ongoing preventive services for a single, serious, or complex condition. - The code captures the added complexity inherent in visits that result from longitudinal care in a management visit setting. - G2211 should not be used if the provider's relationship with the patient is discrete, routine, or time-limited, such as a one-time procedure or acute concern without ongoing care responsibility. - Medicare requires appropriate documentation supporting the medical necessity of the base E/M visit and the longitudinal care relationship or complex condition management for G2211. - Medicare patients are responsible for cost-sharing when G2211 is billed. - These billing rules ensure that G2211 is used to reflect added practitioner work, practice expense resources involved, and related practice costs in managing complex or ongoing care under CMS guidelines starting in 2024.

## **Other relevant codes** - **G2212** - Prolonged office or other outpatient evaluation and management service(s) beyond the maximum required time of the primary procedure which has been selected using total time on the date of the primary service; each additional 15 minutes by the physician or qualified healthcare professional, with or without direct patient contact (list separately in addition to cpt codes 99205, 99215, 99483 for office or other outpatient evaluation and management services) (do not report g2212 on the same date of service as 99358, 99359, 99415, 99416). - **G2213** - Initiation of medication for the treatment of opioid use disorder in the emergency department setting, including assessment, referral to ongoing care, and arranging access to supportive services (list separately in addition to code for primary procedure)
