G2211 is a Medicare add-on code that pays for the extra work involved when a practitioner manages a patient over time. It has been payable since January 1, 2024, and CMS has expanded where it can be used twice since then. This article covers when to report it, which visits it goes with, and the mistakes that lead to denials.
What G2211 pays for
CMS created G2211 to recognize the complexity that comes from a longitudinal relationship with a patient, not from the problem treated at a single visit. You can report it when you are either:
- the continuing focal point for all of the patient's needed health care services, such as a primary care practitioner, or
- providing ongoing care for a single serious condition or a complex condition, such as HIV or sickle cell disease.
The level of the visit doesn't matter, and CMS doesn't limit G2211 by specialty. What matters is the ongoing relationship. In CMS's own example, a primary care practitioner treating a patient's sinus congestion can report G2211, because the complexity comes from being the patient's focal point for care rather than from the sinus problem itself.
G2211 is not meant for care that is discrete or time-limited, such as a one-time visit for a single acute problem with no expected ongoing relationship.
Base codes G2211 can be billed with
G2211 is an add-on code. It is never billed alone, and it must be on the same claim as one of these base E/M codes:
- 99202–99205
- Office or outpatient visit, new patient
- 99211–99215
- Office or outpatient visit, established patient
- 99341–99350
- Home or residence visit (new for 2026): 99341, 99342, 99344, 99345, 99347, 99348, 99349 and 99350
Payment with home or residence visits starts with dates of service on or after January 1, 2026, under the CY 2026 Physician Fee Schedule final rule.
Modifier 25
When G2211 was introduced, Medicare did not pay it if the base E/M visit had modifier 25. Starting January 1, 2025, CMS allows G2211 with a modifier 25 E/M visit when the other service billed that day is one of these:
- An Annual Wellness Visit or the Welcome to Medicare visit (G0402, G0438, G0439)
- Immunization administration (90460, 90461, 90471–90474)
- A Medicare Part B preventive service on CMS's list, such as screening services, depression screening (G0444) or advance care planning (99497, 99498)
If the modifier 25 E/M visit is billed with a procedure, such as a joint injection or a skin biopsy, G2211 is still not payable.
G2211 with modifier 25 is payable only when the same-day service is on CMS's allowed list. Check the list in CMS Change Request 13705 before billing.
Documentation
CMS has not added documentation requirements specific to G2211. The base E/M visit must be medically reasonable and necessary, and the record should support the ongoing relationship: for example, the problem list, the assessment and plan, follow-up instructions, and prior visits with the same practitioner. If your practice bills G2211 for a specialty, make sure the note shows why you are managing the condition over time and not seeing the patient once.
Cost sharing
G2211 is paid under the Physician Fee Schedule, so the patient's Part B deductible and coinsurance apply. Patients may notice an extra line on their statement, so front-desk and billing staff should be ready to explain it.
Common reasons G2211 is denied
- Billed without a qualifying base E/M code on the same claim
- Base E/M has modifier 25 and the same-day service is a procedure, not an allowed preventive service
- Billed with a home or residence visit for a date of service before January 1, 2026
- Billed to a Medicare Advantage or commercial plan that doesn't recognize G2211 or follows different rules
Medicare Advantage, Medicaid and commercial payers set their own policies, so check each payer before adding G2211 to their claims.
