Collaborative Care Model billing: 99492-99494, G0323 and G2214.
CoCM pays more than general behavioral health integration for one reason: it requires more infrastructure, and CMS wants proof that infrastructure actually ran that month, not just that a care manager logged time. Most CoCM denials trace to one missing piece — the psychiatric consultant's caseload review isn't documented, the wrong code was billed against the wrong time threshold, or the claim landed in the same month as a general BHI claim for the same patient. This guide covers the code family, the documentation that survives audit, and the 2026 change that moves FQHCs and RHCs off the old bundled rate.
Key takeaways
- CoCM and general BHI are mutually exclusive per patient per month. Billing 99492 or 99493 alongside 99484 or G0323 for the same patient in the same calendar month is the single most common combination error in this code family, confirmed across multiple corroborating billing references.
- The psychiatric consultant's review has to exist as its own dated record. A care manager's time log alone, without a separately documented and attributable consultant caseload review, does not support a CoCM claim on audit.
- G2214 isn't a downgrade code — it's the correct code for a lower-intensity month. Use it when the fuller 70-/60-minute threshold for 99492/99493 wasn't met, instead of rounding a short month up to the higher code.
- FQHCs and RHCs stopped billing the blended
G0512rate January 1, 2026 and now report the same component codes —99492,99493,99494,G2214— as every other practice.G0323, the general BHI code for these sites, was not affected.
Why CoCM pays more: the three-person requirement
General behavioral health integration is a two-role model — a care manager working under a treating physician's direction. CoCM adds a third, mandatory role: a psychiatric consultant who conducts systematic review of a patient registry and advises the treating physician and care manager, without necessarily ever seeing the patient directly. That third role is what CMS is paying for, and it's also the piece that's missing most often when a CoCM claim gets denied or, worse, gets paid and then clawed back on a post-payment audit.
The model has real process requirements behind it, not just a staffing chart: the patient has to be informed of and agree to CoCM (documented consent, verbal is acceptable if noted), care is tracked against a registry rather than one-off visit notes, and a validated outcome measurement tool — PHQ-9 for depression, GAD-7 for anxiety, or the condition-appropriate equivalent — gets used to track whether the patient is improving. When a patient isn't improving on schedule, the record should show the consultant's review prompted a specific change: a medication recommendation, a treatment plan adjustment, or an escalation. A registry that just accumulates unchanged scores month after month with no documented response is a pattern payers and auditors both look for.
The CoCM code family
| Code | Month / intensity | Approximate time |
|---|---|---|
99492 | Initial month | ~70 minutes combined care manager, physician, and consultant time |
99493 | Subsequent month | ~60 minutes |
+99494 | Add-on, any month (initial or subsequent) | Each additional 30 minutes beyond the base code's threshold |
G2214 | Initial or subsequent month, lower intensity | First 30 minutes of behavioral health care manager time only, when the fuller threshold above wasn't met |
+99494 is an add-on code and is never billed alone — it attaches to 99492 or 99493 for a month where the team's combined time ran past the base code's threshold. G2214 is not an add-on; it's a standalone alternative to 99492 or 99493 for a month where care happened but didn't reach the fuller threshold, so don't append +99494 to G2214.
CoCM versus general BHI: pick one per patient per month
99484 / G0323- Care manager works under the treating physician's direction; a monthly time threshold applies, but there's no mandatory psychiatric consultant.
G0323is the RHC/FQHC equivalent of99484, billed under a clinical psychologist's or clinical social worker's direction.
99492 / 99493 / +99494 / G2214- Adds the mandatory psychiatric consultant conducting systematic, registry-based caseload review.
- Pays at a higher rate than general BHI for the same practice, reflecting the additional required infrastructure.
The two models are mutually exclusive for a given patient in a given calendar month — a practice bills one or the other, never both, because both code families report care-management time for overlapping work under different team structures. This is confirmed consistently across multiple industry billing references; the most frequently cited version of the error is billing 99484 and 99492 (or 99493) for the same patient in the same month. If a patient's care genuinely shifts from one model to the other mid-treatment, close out the first model's billing for that month cleanly before starting the second — don't bill both for one overlapping month.
The 2026 FQHC/RHC transition off G0512
Through 2025, FQHCs and RHCs billed CoCM under a single blended flat-rate code, G0512, instead of the component codes everyone else used. CMS discontinued G0512 effective January 1, 2026; these sites now report the same 99492, 99493, 99494, and G2214 codes as any other practice, unbundled from the old flat rate. This is corroborated by CMS's CY2026 Physician Fee Schedule final rule as reported across multiple industry summaries.
G0323, the general BHI code these same sites use, is a separate code family from G0512/CoCM and was not affected by this change — don't confuse a site's BHI billing pathway with its CoCM pathway when auditing what changed.
If your FQHC or RHC billed G0512 for a patient in December 2025 and CoCM continues into January 2026, that January claim goes out under the new component codes, not G0512 — a scrubber or clearinghouse rule still mapping to G0512 for these sites will reject or, worse, silently underbill the claim rather than flag it for review. Confirm the code mapping changed before your first January CoCM submission, not after a denial batch shows it didn't.
Documentation checklist for a CoCM claim
Every element below has to exist in the chart, not just be inferable from the billed time. This is what a payer or post-payment auditor asks to see first.
- 1Documented patient consent to participate in CoCM, including that they understand cost-sharing may apply — verbal consent is acceptable if it's noted in the record with the date.
- 2A registry entry tracking the patient's diagnosis, treatment plan, and outcome measure scores over time — not a series of disconnected visit notes.
- 3Validated outcome tool scores (PHQ-9, GAD-7, or the condition-appropriate equivalent) recorded at intervals, showing whether the patient is trending toward improvement.
- 4A dated, attributable psychiatric consultant review of the patient's status in the registry — separate from the care manager's own time log, and separate from any direct patient encounter, since the consultant often has none.
- 5A care manager time log totaling the minutes that support the specific code billed — 70 for 99492, 60 for 99493, 30 for G2214, with any add-on 30-minute blocks logged separately for +99494.
- 6A treatment-plan change or escalation note whenever the outcome measure shows the patient isn't improving on the expected timeline — the record should show the consultant's review led somewhere, not just occurred.
Do and don't
- Bill G2214 for a month that fell short of the 99492/99493 time threshold, rather than rounding up.
- Keep the psychiatric consultant's caseload review as its own dated, attributable record, separate from the care manager's log.
- Confirm which code family — CoCM or general BHI — a given patient is in before billing any care-management code for that month.
- Update your code mapping for FQHC/RHC CoCM claims before your first submission under the 2026 component-code structure.
- Don't bill 99492/99493 and 99484/G0323 for the same patient in the same calendar month.
- Don't bill +99494 without a base 99492 or 99493 already on the claim for that month.
- Don't submit a CoCM claim on a care manager's time log alone, with no separate consultant review documented.
- Don't keep billing G0512 for an FQHC/RHC patient on or after January 1, 2026.

Frequently asked questions
Can we bill CoCM (99492/99493) and general BHI (99484 or G0323) for the same patient in the same month?
No. CoCM and general BHI are mutually exclusive care models for a given patient in a given calendar month, confirmed across multiple corroborating industry billing references — a practice bills one model or the other, never both, because the two code families report overlapping care-management time under different team structures. The most common version of this error is billing 99484 and 99492 for the same patient in the same month; pick the model that matches which team actually delivered the care that month, and don't switch mid-month without closing out the first model's time first.
What's the difference between G2214 and 99492?
Both can report the initial month, but 99492 requires the full first-month time threshold — approximately 70 minutes of combined care manager, physician, and consultant time — while G2214 reports a lower-intensity month, the first 30 minutes of behavioral health care manager time, for a patient who doesn't meet the higher threshold that month. G2214 also covers a lower-intensity subsequent month, not only the initial one. Bill 99492 (initial) or 99493 (subsequent) whenever the fuller time threshold is documented and met; bill G2214 when it isn't, rather than rounding up to the higher code on a month that fell short.
Does the psychiatric consultant have to see the patient for a CoCM claim to be billable?
No, and that's precisely why the consultant's review has to be documented on its own — the model is built around a consultant who reviews a caseload registry and advises the care manager and treating physician without necessarily ever having a direct encounter with the patient. What has to exist in the record is proof that the review happened: a dated note attributable to the named consultant showing they reviewed the specific patient's status in the registry and, where indicated, recommended a change in the treatment plan. A care manager's own time log, without that separate consultant documentation, does not support a CoCM claim on audit.
