There is a Medicare add-on code that many primary care and specialty practices can bill on visits where they provide ongoing care, that requires no separate service, and that is easy to miss. It is G2211, the visit-complexity add-on.
What G2211 actually is
G2211 is an add-on you append to an office or outpatient evaluation and management (E/M) visit, and, starting January 1, 2026, to a home or residence E/M visit, when you are the clinician providing ongoing, longitudinal care for a patient's overall health or for a single, serious or complex condition. It is meant to recognize the extra cognitive work of being the doctor who knows the whole patient over time, not just the visit in front of you.
You do not perform a separate service to bill it, but the record still has to show the visit was medically reasonable and necessary and reflect the ongoing relationship. One limit to know: Medicare generally does not pay G2211 when the visit is billed with modifier 25, except when the visit is on the same day as an annual wellness visit, a vaccine administration, or a Part B preventive service.
If you are the continuing physician for a patient with, say, diabetes and hypertension, and you see them for a routine visit, that visit likely supports G2211.
Why it gets left on the table
Three reasons come up again and again:
- Uncertainty about eligibility. Providers are not sure which visits qualify, so they skip it to be safe.
- It is not in the workflow. If the EHR does not prompt for it and the people who code the visit are not trained to add it, it never gets added.
- It looks small. On a single claim the add-on is modest, so it feels like it is not worth the trouble. Across a panel of longitudinal patients, over a year, it is real money.
CMS has proposed making it bigger
For calendar year 2027, CMS has proposed turning G2211 into a modifier on the E/M visit. Under the proposal, the modifier would increase payment for the associated E/M visit by 16 percent instead of a flat amount, and a separate modifier for practitioners in a Shared Savings Program ACO or the LEAD Model would increase it by 32 percent. This is a proposal, not a final rule, and CMS could change it before it takes effect.
Practices that build the habit now would be ready if the change is finalized. Either way, the add-on is payable today.
How to actually capture it
- Decide, as a policy, which of your visits represent longitudinal or complex continuing care.
- Make the add-on a default prompt in your visit workflow, not a thing someone has to remember.
- Train the people who touch the claim so it goes out consistently.
How SmartOps Health helps
SmartOps Health flags the patients whose visits support G2211 and puts a one-tap reminder in front of your team so the add-on gets appended every eligible visit instead of slipping through. It turns a code people forget into money you actually collect.
