What Is Changing with G2211 in the 2027 Proposed Rule?
As of July 14, 2026, the CMS 2027 Medicare Physician Fee Schedule proposed rule (CMS-1848-P) proposes converting HCPCS code G2211, the office/outpatient E/M visit complexity add-on, from a flat-payment add-on code into a modifier that adds approximately 16 percent to the underlying E/M service. G2211 was first implemented for CY 2025 and has been billed as a standalone add-on code alongside qualifying E/M visits. The restructuring to a percentage modifier changes the payment calculation and the billing workflow for every provider who reports it.
From flat code to percentage modifier. Instead of a fixed dollar amount, G2211 would add 16 percent to whatever E/M code it accompanies, meaning higher-level visits yield a higher add-on payment.
The qualifying criteria remain the same. G2211 still applies to visits involving the management of a condition for which the provider has an ongoing relationship with the patient, including conditions expected to require continuing care.
Urgent care eligibility depends on the visit. Episodic walk-in visits do not qualify. But established patients returning for ongoing management of a condition may qualify when the documentation supports it.
Does G2211 Apply to Urgent Care Visits?
G2211 was designed for visits where the provider manages a condition within an ongoing longitudinal relationship. In primary care and specialty settings, this covers the majority of visits. In urgent care, the application is narrower because most UC visits are episodic. A patient walking in for a sore throat or a sprained ankle is not in an ongoing management relationship with the UC provider for that condition.
However, a subset of urgent care visits does qualify. Established patients who return to the same UC center for ongoing management of a chronic condition, such as hypertension follow-up, diabetes management between PCP appointments, or recurring wound care, may meet the G2211 criteria if the documentation supports an ongoing care relationship. The UC provider must document that the visit involves management of a condition for which the patient has a continuing relationship with that provider or practice, not just that the patient has been seen before.
Across the billing companies we vet for urgent care centers, the practices that capture G2211 appropriately are those whose billing teams identify qualifying visits based on documentation, not those that apply it to every established patient encounter. The distinction matters because overbilling G2211 on episodic visits invites audit risk, while missing it on qualifying ongoing-care visits leaves revenue uncaptured.
How Does the Restructuring Change the Math?
Under the current flat-code structure, G2211 pays the same amount regardless of the E/M level it accompanies. Whether reported alongside a 99213 or a 99215, the add-on payment is identical. Under the proposed modifier structure, G2211 would add 16 percent of the underlying E/M payment, which means higher-level visits produce a higher add-on dollar amount.
| E/M Code | Approx. 2026 Payment | Current G2211 (Flat) | Proposed G2211 (16% Modifier) |
| 99213 | $100 | $16 (flat) | $16 (16% of $100) |
| 99214 | $130 | $16 (flat) | $20.80 (16% of $130) |
| 99215 | $175 | $16 (flat) | $28 (16% of $175) |
For urgent care centers that bill G2211 primarily alongside 99214 visits (the most common UC E/M level), the percentage modifier produces a slightly higher payment than the flat code. For centers that bill it alongside 99215, the increase is more meaningful. For 99213 visits, the payment is roughly equivalent. The net revenue impact depends on the E/M level distribution of qualifying visits.
One question we hear from UC practice managers is whether this change makes G2211 worth pursuing for the visits that qualify. The answer is yes, particularly for centers that see established patients for ongoing care. The percentage modifier rewards higher-complexity visits more than the flat code did, which aligns the add-on with the clinical work involved.
If your urgent care center bills G2211 on qualifying visits and you need to understand how the 2027 restructuring affects your revenue, or if you are not billing it and should be, a billing partner with urgent care experience can evaluate your eligibility and projected impact.
What Should Urgent Care Billing Teams Do Now?
The rule is proposed, not finalized. The comment period closes September 14, 2026. But these steps prepare your billing operation.
Audit your current G2211 usage. Determine how many claims in the last 12 months included G2211. If the answer is zero, review whether any qualifying visits were missed. If the number is high, verify that every claim meets the ongoing-care documentation standard.
Identify which UC visits qualify. Established patients with documented ongoing management relationships are the target. Episodic walk-in visits for acute complaints without a continuing care context do not qualify, and billing G2211 on those visits creates audit exposure.
Model the revenue impact of the modifier switch. Calculate the difference between the flat G2211 payment and 16 percent of each E/M level you bill it alongside. For most UC centers, the net change is modest but positive for higher-level visits.
Update your billing system when the final rule publishes. If CMS finalizes the modifier structure, your practice management system will need to apply the percentage calculation rather than a flat fee. Your billing company should handle this update proactively.
Document the ongoing-care relationship in the visit note. For every visit where G2211 is reported, the note must show that the provider is managing a condition within a continuing care relationship, not just performing an episodic evaluation. Without this documentation, the claim is vulnerable.
Frequently Asked Questions
G2211 is an add-on code reported alongside qualifying office and outpatient E/M visits. It was created to recognize the additional resources involved in managing patients within an ongoing longitudinal care relationship. CMS implemented it for CY 2025, and the 2027 proposed rule would convert it from a flat-payment code to a 16 percent modifier.
Yes, on qualifying visits. Established patients returning to the same UC center for ongoing management of a chronic or recurring condition may qualify when the documentation supports a continuing care relationship. Episodic walk-in visits for acute complaints without an ongoing management context do not qualify.
Under the current flat structure, G2211 pays approximately $16 regardless of the E/M level. Under the proposed 2027 modifier structure, it would pay 16 percent of the underlying E/M code, ranging from approximately $16 for a 99213 to $28 for a 99215.
No. As of August 2026, it is a proposed change in CMS-1848-P. The comment period closes September 14, 2026. The final rule is expected in November 2026, with changes effective January 1, 2027.
CMS allows G2211 on new patient visits when the provider initiates management of a condition that will require ongoing care. However, in urgent care, most new patient visits are episodic and would not meet this standard. The code is used most frequently with established patient encounters.
Next Steps
Start by auditing your current G2211 usage to determine whether qualifying visits are being captured. If your billing team has not been reporting G2211 on any claims, the restructuring is a good reason to evaluate which visits qualify.
For practices that need a billing partner with urgent care E/M coding expertise, Urgent Care Bill Co connects you with vetted billing companies that understand G2211 eligibility, the 2027 modifier restructuring, and the documentation standards that protect these claims.
The G2211 restructuring is a modest but real revenue opportunity for urgent care centers that bill qualifying visits. Get matched with an urgent care billing specialist who can evaluate your eligibility and prepare your workflow for 2027.
