G2211
Complex e/m visit add on
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, or with medical care services that are part of ongoing care related to a patient's single, serious condition or a complex condition. CMS 2026 wRVU 0.33. Add-on to office E/M codes 99202 through 99215.
G2211 cannot be billed with modifier 25 in most situations. Here is the rule, the exceptions, and how to decide which to use on a same-day encounter.
G2211 attaches to an office E/M when you are the continuing focal point of a patient's care. Here is who qualifies, with concrete examples and the cost-share caveat.
When to use it
G2211 is the continuity add-on. Append it to an office E/M (99202 through 99215) under one of two conditions: you are the continuing focal point for all of the patient's health care (the primary-care framing), OR you are the ongoing care provider for a patient's single serious condition or a complex condition (the subspecialty framing).
Full guidance
Common eligible scenarios: a routine primary care follow-up for chronic disease management; an endocrinology continuity visit for diabetes; an oncology survivorship visit; a rheumatology disease-modifying-medication monitoring visit; a nephrology follow-up for CKD progression. Ineligible scenarios: one-time consults, urgent care visits, hospital follow-up where you are not the longitudinal provider, and visits where modifier 25 is appended to the primary E/M (explicitly prohibited).
Documentation checklist
- ✓The note must reflect your role as the continuity or longitudinal provider. A single sentence is sufficient: "I am the continuing focal point for this patient's primary care" or "I provide ongoing care for this patient's [condition]."
- ✓Standalone code; no patient consent required.
- ✓Attach G2211 as a separate line on the claim, no modifier required.
- ✓Do not append modifier 25 to G2211. The G2211 code itself signals the add-on relationship.
- ✓G2211 is not eligible when modifier 25 is appended to the primary E/M (e.g., when a same-day minor procedure was performed). CMS treats modifier-25 encounters as non-continuity by definition.
Common pitfalls
- !Billing G2211 with modifier 25 on the primary E/M. Explicitly prohibited; the claim will be denied or down-coded.
- !Billing G2211 for one-time consults or urgent care visits. The continuity framing requires that you are the longitudinal provider, not a one-off.
- !Not billing it at all. Medicare estimates G2211 should be appended to roughly 38 percent of office E/Ms; observed capture rates remain under 5 percent in many practices. This is the largest single unrecovered wRVU pool in primary care.
- !Billing G2211 with hospital-discharge follow-up where you are not the longitudinal PCP. The visit must be part of an ongoing continuity relationship, not a one-time transitional encounter.
- !Forgetting G2211 on new-patient visits. CMS clarified in 2024 that new patient visits are eligible when continuity care is intended (e.g., establishing primary care).
- !Coding G2211 alongside non-eligible primary codes (e.g., 99211, telehealth-only codes without continuity intent). Verify the primary E/M is 99202 through 99215.
Payer notes
Medicare started paying G2211 separately as of January 2024 after delaying the original 2021 implementation. CMS 2026 wRVU is 0.33, allowable approximately $16 at the national-GPCI conversion factor. Commercial payer coverage varies: UnitedHealthcare, Aetna, and BCBS plans typically reimburse G2211 but at variable rates; Cigna requires specific medical-record documentation. Medicare Advantage plans follow Medicare guidelines but some require G2211 to be coded under a specific HCC-eligible diagnosis.
