We are seeing an increase in the use of G2211 code by optometrists, and while appropriate at times, providers should make sure to use it appropriately.

What it is:

An add-on code for E/M services (like 99202-99215).

Visit complexity inherent to evaluation and management associated with medical care services that serve as the continuing focal point for all needed health care services and/or with medical care services that are part of ongoing care related to a patient’s single, serious condition or a complex condition. (Add-on code, list separately in addition to office/outpatient evaluation and management visit, new or established)

The code was created to captures the complexity of visits that are the continuing focal point for a patient’s care. Ideally, it rewards providers for building longitudinal relationships, managing serious or complex conditions with continuity, and coordinating care.

When to Use It:

When you provide ongoing care for a single, serious, or complex condition (e.g., managing cancer, diabetes, sleep apnea).

For services that are part of a consistent, long-term relationship, not a one-time, discrete visit.

Code G2211 may be reported with CPT codes 99202-99205, 99211-99215 as an add-on code (but may not be reported without those codes)

All rules for reporting E/M services apply to billing code G2211. And G2211 is separately payable to the billing provider.

Reporting Requirements

CMS has not specified any additional medical record documentation requirements for reporting the HCPCS code G2211 add-on code. But medical reviewers may use the medical record documentation to confirm the medical necessity of the visit and the patient care relationship as appropriate.

No specific diagnosis is required for HCPCS code G2211 to be billed. For the billing practitioner, it would be appropriate to report a health condition that is a single, serious condition and/or a complex condition for which the billing practitioner is engaging the patient in a continuous and active collaborative plan of care related to an identified health condition—the management of which requires the direction of a practitioner with specialized clinical knowledge, skill, and experience. CMS states that such collaborative care includes patient education, expectations and responsibilities, shared decision-making around therapeutic goals, and shared commitments to achieve those goals.

CMS provide several examples to clarify the use of HCPCS code G2211 in the context of specialty care. In eye care this could include serious conditions such as glaucoma, age-related macular degeneration or other conditions requiring long-term monitoring, counseling and care considerations

When NOT to Use It:

For routine, time-limited, or episodic care where a longitudinal relationship isn’t established or planned.

For any 920XX services.

Additionally, CMS will deny payment of G2211 when modifier -25 is on the claim for any service except when on the same day as an AWV, vaccine administration, or any Medicare Part B preventive service furnished in the office.

Why it Matters:

It supports and recognizes the value of primary care and specialists who provide comprehensive, relationship-based care, preventing undervaluation of these services.

Hints For Success:

While the data for audit with G2211 is currently low, it is recommended that your medical record be implicit in stating that you are managing a condition for which you are the central hub in patient care and management.  This reduces your exposure should your submitted claims be called into question.

2026 Updates: While Medicare expands G2211, private payers like Ambetter are discontinuing it for some services in 2026, so verify coverage with each insurer.
