Most psychiatric prescribers are familiar with E/M codes like 99213 and 99214. But what happens when an appointment runs significantly longer than expected? Or when you are providing ongoing care for a patient with a complex psychiatric condition?
There are additional billing codes that may apply in certain circumstances. Three worth understanding are G2211, G2212 and 99417.
Here is the simple version:
Because you may be providing services that qualify for additional reimbursement without realizing it. And using the wrong code, or applying the wrong time threshold, can result in denied claims or overpayments.
For example, an 80-minute new patient psychiatric evaluation may qualify for an additional prolonged-service payment under a commercial insurer that follows CPT rules, but not under Medicare.
And if you are providing continuing psychiatric care to a Medicare patient, G2211 may be relevant even when the appointment is relatively brief.
The important point is that these codes are not interchangeable. Two concern additional time, while the third concerns the nature of your ongoing clinical responsibility.
Let us look at how they work, when they apply, and where Medicare and commercial insurance rules differ.
Start with what they share. Both are prolonged office/outpatient E/M add-ons. Both attach to the level 5 office/outpatient codes, 99205 and 99215, which is the scenario this post is about. (Medicare's descriptor for G2212 also lists 99483, the cognitive assessment and care planning service, which carries its own threshold and its own timeframe. Treat 99205 and 99215 as the office/outpatient case rather than the whole list.) Both are reported in 15-minute units. Both require that the primary E/M was selected by time.
The difference is where the clock starts, and it is not a small difference. These thresholds use total qualifying E/M time on the date of service, not just face-to-face time. Qualifying same-day work by the billing clinician may include record review, evaluation, coordination and documentation. Do not count time separately billed for another service. See Choosing Time vs MDM for how time-based selection works.
| After this base code | First unit of 99417 (CPT) | First unit of G2212 (Medicare) |
|---|---|---|
| 99205, new patient, 60 to 74 min | 75 minutes | 89 minutes |
| 99215, established patient, 40 to 54 min | 55 minutes | 69 minutes |
Fourteen minutes apart in both rows. That is not a coincidence and it is not arbitrary. 99417 counts from the bottom of the level 5 time range. G2212 counts from the top. The gap between them is exactly the width of the range.
Medicare's own ladder, as its claims-processing instructions still carry it:
| CPT code(s) | Total time required |
|---|---|
| 99205 | 60 to 74 minutes |
| 99205 and G2212 x1 | 89 to 103 minutes |
| 99205 and G2212 x2 | 104 to 118 minutes |
| 99215 | 40 to 54 minutes |
| 99215 and G2212 x1 | 69 to 83 minutes |
| 99215 and G2212 x2 | 84 to 98 minutes |
For Medicare, 75 to 88 minutes still supports 99205 alone; the first G2212 unit begins at 89 minutes. Thus an 80-minute new-patient intake coded by time supports 99205 without a prolonged-services add-on under Medicare. The same 80 minutes on a commercial plan that follows CPT supports 99205 plus one unit of 99417. Same work, same documentation, different claim, because the payer is different.
G2212 also carries two restrictions worth knowing. It is not reported for any time unit under 15 minutes, which means no partial credit, and it is not reported on the same date as 99354, 99355, 99358, 99359, 99415 or 99416.
This is the part worth understanding rather than memorizing, because once you have it you can reconstruct the thresholds without looking them up.
CMS's objection to CPT's version was that counting from the minimum pays twice for the same minutes. From the CY2021 final rule:
As a specific example, the time range for CPT code 99215 is 40-54 minutes. If the reporting practitioner spent 55 minutes of time, 14 of those minutes are included in the services described by CPT code 99215. Therefore, only 1 minute should be counted towards the additional 15 minutes needed to report CPT code 99417.
That is CMS's rationale, rather than a universally accepted interpretation of CPT: CMS viewed the level 5 E/M payment as already accounting for the time within its stated range, and regarded CPT's earlier prolonged-services threshold as counting some of that time again. CPT and Medicare use different approaches.
CMS considered adopting CPT's reading and declined, saying it preferred to align with CPT but believed the descriptor was unclear. It then created G2212 "to be used when billing Medicare for this service instead of CPT code 99417." The two codes exist because CMS and the CPT Editorial Panel did not agree, and that disagreement was never resolved. It was forked.
Which is why "Medicare equivalent, same rules, different code" is a costly way to remember it. The code is different because the rule is different.
G2211 has nothing to do with minutes. It pays for the complexity inherent in being the clinician who holds the thread:
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, or complex condition.
CMS was explicit in the CY2024 rule that this is about the relationship rather than the patient: the code "is not based on the characteristics of particular patients" but "rather the relationship between the patient and the practitioner." CMS's own FAQ adds that the code is not limited to any specialty and that no particular diagnosis is required.
That cuts both ways, and the second direction is the one to be careful about. Doing longitudinal psychiatric care does not make a given encounter eligible. CMS describes the test as whether you are the continuing focal point for the patient's care, or are providing ongoing care for a single serious or complex condition, and says the code is not appropriate where the practitioner "has not taken responsibility for ongoing medical care for a given patient with consistency and continuity over time, or does not plan to" do so. A serious diagnosis on its own does not get you there, and neither does the fact that the visit was psychiatric. CMS has specified no additional documentation requirements, and says its reviewers may use the record to confirm the medical necessity of the visit and the care relationship.
Its payment history is where most of the confusion comes from, and the timeline is worth getting right. CMS finalized the code for 2021. Congress then imposed a statutory moratorium on Medicare payment for it in the Consolidated Appropriations Act of 2021, which ran through 31 December 2023. In the CY2024 final rule CMS finalized "changing the status of HCPCS code G2211 to make it separately payable by assigning it an 'active' status indicator, effective January 1, 2024." In the CY2026 final rule it went further, allowing G2211 as an add-on to the home or residence E/M visit family as well, with the descriptor refined to read "in addition to home or residence or office/outpatient evaluation and management service."
So if you learned that G2211 was bundled, that was true, by statute, and it stopped being true on 1 January 2024. If you learned it was office and outpatient only, that was the right answer until 1 January 2026.
The restriction that matters most in psychiatry is modifier 25, but there is an important exception.
Medicare generally does not pay G2211 when modifier 25 is appended to the associated office/outpatient E/M service. That was finalized in the CY2024 rule and it still holds. However, beginning 1 January 2025, CMS permits G2211 when that E/M service is performed on the same day as an annual wellness visit, vaccine administration, or another qualifying Medicare Part B preventive service furnished in the office or outpatient setting. CMS confirmed that the Welcome to Medicare visit counts, and from 1 January 2026 the same exception extends to the home or residence E/M codes.
Read the exception for what it is. It covers preventive services. It is not a general softening of the rule, CMS declined to extend it to other services, and it does nothing for the ordinary case where modifier 25 is on a psychiatric claim for some other reason.
So the practical issue remains important. If your billing system routinely appends modifier 25 to an E/M visit, you may be losing otherwise appropriate G2211 reimbursement whenever the exception does not apply. That connects to something already covered in the CPT Coding Logic material: modifier 25 should reflect the services actually provided and the applicable billing requirements, not simply be added to every claim.
One more thing worth knowing, because it is the opposite of what people assume: CMS says G2211 may be billed during the same service period as care management services, and does not consider the two duplicative.
This is already stated in the archive for 99417. It holds for G2212 too, and the reason is in the descriptors rather than in a separate rule.
Both prolonged codes extend a primary E/M "selected using total time." When you report a psychotherapy add-on, 90833, 90836 or 90838, the E/M level must be selected by medical decision making. Time-based selection is off the table for that visit. So there is no time-selected primary service for a prolonged code to extend, and that is true whether the payer is Medicare or commercial.
Two things follow that are easy to get backwards:
G2211 is a separate question, because it is not a time code and the lane rule does not reach it. I have not found CMS text addressing G2211 alongside psychotherapy add-ons specifically, so I am not going to assert an answer. The restriction I can point to in the rule is modifier 25.
Everything above about G2212 and G2211 is Medicare policy. 99417 is CPT's code, and CPT does not pay claims.
A commercial plan makes its own decisions: whether it recognizes 99417 at all, which threshold it applies if it does, and whether it pays G2211. None of those decisions are governed by the CMS timeline, and a plan is free to change them at renewal.
My own experience, offered as experience rather than as a rule: I billed G2211 in private practice around 2023 and 2024, and some commercial payers paid it. Then they stopped, and what I was told was that it was bundled into the E/M.
The experience is supported by published payer policies. UnitedHealthcare's commercial policy bulletin made G2211 non-separately reimbursable beginning September 1, 2024. Select Health commercial plans stopped separate reimbursement January 1, 2026. Blue Cross of Idaho excluded commercial products beginning June 1, 2026, while allowing eligible Medicare Advantage payment. Health Net California announced nonpayment for G2211 and G2212 beginning April 1, 2026 for products specified in its notice. These are payer- and product-specific policies, not a universal rule for commercial insurance.
Both things can be true at once, and the distinction is the reason this post exists. Medicare's bundling of G2211 was statutory and it ended. A commercial payer telling you a code is bundled into the E/M is describing its own payment policy. It is not reporting the CMS status, it does not mean the code is invalid, and it does not carry over to your Medicare claims.
The practical version: the threshold you use is a function of the payer, not of the visit. Confirm the policy before you rely on it, and do not carry a Medicare threshold onto a commercial claim or a commercial threshold onto a Medicare claim.
Four questions, in order, on any long visit:
And separately from all of it: for Medicare patients receiving longitudinal psychiatric care, G2211 is worth evaluating. Eligibility depends on the ongoing clinical relationship, the services provided, the documentation, and the applicable billing restrictions, modifier 25 among them.
CPT Coding Logic for PMHNPs is the one-page reference, with the PDF and an editable Word version, and it covers the psychotherapy and prolonged-services interaction in more detail.
Choosing Time vs MDM covers the lane question, which is upstream of everything here.
Spravato and "Creative" Billing is what happens when prolonged services get stacked onto observation time, and it is worth reading because the thread works through why paid is not the same as defensible.
The full CY2021 CMS transmittal that G2212 comes from is preserved verbatim in the archive at CMS: Prolonged Office/Outpatient E/M Services, Part 1.
And for the federal rules themselves, rather than my reading of them:
Where this post and those documents disagree, they are right and I am wrong. Tell me and I will fix it.
Your turn. Have you had a commercial payer tell you a code was bundled, and did you ever find out whether that was policy or an edit?
