Why it matters in orthopedics
CMS does not limit G2211 by specialty, so orthopedic surgeons can report it, but many orthopedic encounters don’t fit. CMS’s G2211 FAQ names treatment for a fracture as an example of discrete, time-limited care where the add-on is not appropriate. Orthopedic visits also often carry modifier 25 for a same-day injection or minor procedure, which blocks G2211 payment. Our guide to billing an E/M on an injection day explains those rules.
How it works
Base codes: office/outpatient visits 99202 to 99205 and 99211 to 99215, and, since January 1, 2026, home or residence visits 99341, 99342, 99344, 99345 and 99347 to 99350. It cannot be added to inpatient, emergency department or nursing facility E/M codes.
Payment: about 0.52 total RVUs in the office setting for CY 2026, with the usual Part B deductible and coinsurance.
Modifier 25 limit: Medicare denies G2211 when the base visit carries modifier 25, unless the other same-day service is an annual wellness visit, a vaccine administration or a Part B preventive service (allowed since January 1, 2025).
Documentation: CMS requires no extra documentation beyond medical necessity for the visit, but the record should show the ongoing relationship, for example through diagnoses, the assessment and plan, and continuity over time.
Proposed for CY 2027 (not final): CMS would replace G2211 with a modifier worth 16% of the visit’s payment, or 32% for clinicians in Shared Savings Program or LEAD Model ACOs. The modifier 25 limits would continue. See our CY 2027 Physician Fee Schedule overview.
Orthopedic example
A surgeon who has managed a patient’s progressive, nonoperative hip osteoarthritis for several years, revising the plan of care at each visit and coordinating therapy, imaging and injections, may meet CMS’s description of ongoing care for one serious or complex condition, as long as no modifier 25 is on the visit. By contrast, G2211 does not fit a few weeks of care for a closed wrist fracture, a visit billed with modifier 25 alongside a 20610 knee injection, or routine post-operative visits inside a global surgical package, which are not separately payable.
Common denial triggers
The base E/M has modifier 25 for a same-day procedure, such as a joint injection.
G2211 is billed with a non-qualifying E/M family, such as a hospital visit.
G2211 is reported for one-time consultations or episodic care, with no documented ongoing relationship, which creates audit risk even when it pays.
G2211 is attached to post-operative visits that fall within a global period.
How to prevent or fix
Add a claim edit that stops G2211 on any office or home E/M line with modifier 25 unless the other service is an allowed preventive service. Train surgeons to reserve G2211 for longitudinal, condition-focused relationships and to document that relationship in the assessment and plan. Audit a sample of G2211 claims each quarter. If CMS finalizes the modifier approach for CY 2027, update charge capture before January 1, 2027. Confirm borderline cases with your MAC.
Frequently asked questions
Can an orthopedic surgeon bill G2211?
Yes, when the relationship fits. CMS does not restrict G2211 to primary care or any specialty. It applies when the practitioner serves as the patient’s ongoing hub for all needed care or manages one serious or complex condition over time. CMS’s FAQ says it is not appropriate for discrete, routine or time-limited relationships, and it lists treatment for a fracture as an example. Document the ongoing relationship whenever you report it.
Is G2211 payable on an E/M with modifier 25 for a same-day joint injection?
No. Medicare denies G2211 when the associated office/outpatient E/M visit is reported with modifier 25 by the same practitioner on the same day. The only exceptions, in place since January 1, 2025, are when the other service is an annual wellness visit, a vaccine administration or a Medicare Part B preventive service. A knee or shoulder injection does not qualify, so G2211 would not be paid on that visit.
What happens to G2211 in 2027?
CMS’s CY 2027 proposed rule would replace G2211 with a payment modifier that adds 16% to the base visit’s payment instead of a flat add-on, and a second modifier that adds 32% for clinicians in Shared Savings Program or LEAD Model ACOs. The same modifier 25 limits would apply. These are proposals; CMS had not published the final rule as of October 14, 2026, and expects most changes to take effect January 1, 2027.
