G2211 CPT Code: The Visit Complexity Add-On Explained
What the add-on pays for, when Medicare denies it, what it pays in 2026, and what CMS proposed for 2027.
Short answer: G2211 is a Medicare HCPCS add-on for an evaluation and management (E/M) visit when the practitioner is the patient’s continuing focal point for all care or provides ongoing care for one serious or complex condition. It is separately payable with office/outpatient visits from January 1, 2024, and home or residence visits from January 1, 2026.
Decide whether the care relationship qualifies before adding G2211. The diagnosis and visit level alone do not establish eligibility.
Report G2211 on the same claim as its base E/M visit. Then check modifier 25, the visit record and patient cost sharing.
TL;DR: G2211 in four lines
What it is: an add-on to an office/outpatient or home or residence E/M visit, never billed alone.
The test: the practitioner is the continuing focal point for all care, or gives ongoing care for one serious or complex condition.
Modifier 25: denied on a modifier 25 visit by the same practitioner, same patient, same day, unless the other service is an annual wellness visit, a vaccine administration or another Part B preventive service.
The patient: Part B deductible and coinsurance apply.
The G2211 CPT code description, word for word
As refined in the CY2026 Physician Fee Schedule final rule, the descriptor reads: “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 home or residence or office/outpatient evaluation and management service, new or established).”
Every rule for reporting the base E/M visit applies to it.
How G2211 changed from 2021 to 2026
- 2021: CMS consolidated earlier visit complexity add-ons into G2211; legislation delayed payment.
- 2024: separate Medicare payment began January 1.
- 2025: the modifier 25 exception began for preventive services.
- 2026: home or residence E/M visits became eligible. Sources: CY2021, CY2024, CY2025 and CY2026 final rules.
Who can bill G2211, and for which relationships
| Visit family | Eligible E/M codes |
|---|---|
| Office/outpatient | 99202 to 99205; 99211 to 99215 |
| Home or residence, from January 1, 2026 | 99341, 99342, 99344, 99345; 99347 to 99350 |
Any practitioner eligible to bill these E/M codes may report G2211 when its criteria are met. CMS imposes no specialty restriction; payment applies in facility and non-facility settings.
The two relationships CMS describes
- Continuing focal point for all care: a primary care visit for sinus congestion can qualify because of the practitioner’s continuing responsibility for the patient.
- Ongoing care for one serious or complex condition: an infectious disease physician managing HIV can qualify without directing all other care. The practitioner maintains an active, collaborative care plan requiring specialized knowledge, skill and experience. Source: CMS G2211 FAQ; MM13473.
When G2211 does not fit
CMS rules it out for a relationship “of a discrete, routine, or time-limited nature”, such as, but not limited to, a mole removal, a simple virus, seasonal allergy counseling, initial-onset reflux or a fracture, where comorbidities are absent or not addressed. It also does not fit when the billing practitioner has not taken responsibility for the patient’s ongoing care with consistency and continuity over time, or does not plan to.
When to use G2211: examples and edge cases
Coding judgment on a specific visit stays with your billing practitioner; confirm edge cases with your MAC.

G2211 billing guidelines in four checks
1. Report the base visit
G2211 is reported per visit, not per month. CMS’s G2211 FAQ says it “may not be reported without reporting an O/O or home or residence E/M base code visit.” The visit itself must be medically reasonable and necessary.
2. Check the visit for modifier 25
Modifier 25 identifies an E/M visit that is significant and separately identifiable from another service. Medicare generally denies G2211 when the same practitioner reports that modifier for the same patient on the same day. The exception is a visit alongside an AWV, vaccine administration or another Medicare Part B preventive service; see the examples table (MM13473; CMS G2211 FAQ).
3. Meet the G2211 documentation requirements
CMS has specified no additional documentation for G2211. Its reviewers may use the record to confirm medical necessity and the care relationship; diagnoses, the assessment and plan of care, and other codes reported can support it. Ask your Medicare Administrative Contractor (MAC) about documenting the underlying visit, and see CMS’s Evaluation and Management Services Guide.
4. Expect patient cost sharing
G2211 carries the usual Part B cost sharing: 20 percent coinsurance and any unmet annual deductible. The Part B deductible is $283 in 2026 (MM14279).
Common G2211 billing mistakes
Two readings of G2211 that CMS rules out
“It needs a qualifying diagnosis.” CMS requires no specific diagnosis; the relationship decides.
“Only my own visits can carry it.” In a team-based care practice, a colleague’s visit may carry it when every other requirement is met.

Key takeaways
- Put G2211 on the same claim as its office/outpatient or home or residence E/M base code, never alone.
- Ask one question first: is this practitioner the patient’s focal point, or managing one serious or complex condition over time?
- Drop it from a same-practitioner modifier 25 visit unless the other service is preventive, such as an annual wellness visit.
- Let the diagnoses, assessment and plan of care show the relationship; CMS adds no documentation rule, but reviewers may check the record.
- Expect no separate G2211 payment at an RHC or FQHC, and check each non-Medicare payer’s own policy before billing it.
Questions about G2211 billing
Is G2211 a CPT code or a HCPCS code?
HCPCS. CMS created G2211 as a HCPCS code, though billing teams often call it the G2211 CPT code. The visit codes it is listed with, such as 99202 to 99215, are AMA CPT codes.
Can G2211 be billed with a new patient visit?
Yes. The descriptor covers new or established patients, and the base codes include 99202 to 99205. It fits only when the practitioner takes, or plans to take, responsibility for the patient’s ongoing care.
Can G2211 be billed with 99211?
Yes. CMS lists 99211 to 99215 among the base codes and allows the add-on with office/outpatient visits of any level, subject to the relationship test.
How often does a patient need to be seen for G2211 to apply?
CMS gives no definition of “longitudinal” in its G2211 FAQ. Asked about patients seen once a year or less often, it answered that the add-on can be billed as long as the relationship meets the focal-point or serious-or-complex-condition test.
Is G2211 only for Medicare?
CMS created G2211 for the Medicare Physician Fee Schedule, and the rules in this guide govern Medicare Part B claims. Before billing it to any other payer, including a Medicare Advantage plan or a Medicaid program, check that payer’s own policy.
Do FQHCs and RHCs get paid for G2211?
Not separately. CMS bundles it into the RHC all-inclusive rate or the FQHC prospective payment system rate with the visit.
What does Medicare pay for G2211?
Medicare pays G2211 under the Physician Fee Schedule, as its own line beside the E/M visit. CMS’s Physician Fee Schedule Look-Up Tool lists its relative value units and its payment amounts, nationally and by MAC locality.
G2211 is a Medicare Part B HCPCS add-on that physician practices report with eligible office/outpatient or home or residence E/M visits. It reflects the practitioner’s ongoing care relationship with the patient. Companian does not offer G2211; for chronic care management, your team refers; we handle enrollment, outreach and documentation. You bill monthly under your license.
