Behavioral & Mental Health Billing

Standing up Collaborative Care billing (99492-99494) in a primary-care-embedded team

Short answer: CoCM is a time-based, calendar-month benefit. One primary-care practitioner bills, a behavioral health care manager runs the panel, and a psychiatric consultant advises. You get paid on accumulated minutes per patient per month, so the whole model lives or dies on one artifact: a behavioral care manager time log that survives an audit. This page shows how to build it.

The care team behind one claim

Three roles, one billing practitioner, one registry

CoCM is not a visit code. It is a team model the treating practitioner bills on behalf of, using a registry-tracked panel and measurement-based care. Get the roles clean before you touch a claim.

Treating practitioner

The billing provider

PCP, NP, or PA who owns the patient relationship
Bills 99492 / 99493 / 99494 under their NPI
Directs care, prescribes, adjusts the plan on consultant input
Secures patient consent, documented once and noted

BHCM

Behavioral health care manager

The minutes engine

Runs the registry, tracks PHQ-9 / GAD-7 scores over time
Delivers brief interventions, care coordination, follow-up
Logs every minute, face-to-face and non-face-to-face
This is where your billable time is created and defended

The specialist input

Reviews the panel with the care manager, typically weekly

What each code actually buys

The CoCM code ladder, by minutes and month

These are CMS Psychiatric Collaborative Care Management codes. The threshold is total treatment-team time for the patient in a single calendar month, not per contact.

99492Initial

First calendar month the patient enters CoCM. Covers assessment, registry setup, initiating the care plan and consultant review.

first 70 min

99493Subsequent

Any month after the first. Ongoing tracking, treatment revisions, relapse-prevention work, continued consultant input.

first 60 min

99494Add-on

Reported with 99492 or 99493. Bill it for each additional 30-minute block of team time in the same month. Repeatable.

+30 min each

G2214Short month

The code most clinics forget. Initial or subsequent CoCM at the first 30 minutes in a month, for panels that do not reach the 60-70 minute floor. It captures real work that would otherwise go unbilled.

Reach the 70-minute floor and you bill 99492. Cross 100 minutes and one 99494 add-on attaches. Minutes below the next 30-minute block do not round up, they carry as documentation of effort, not as a billed unit. Under 36 minutes in a later month, you are in G2214 territory, not 99493.

The artifact that gets paid, and stays paid

The behavioral care manager time log that survives audit

A payer will not challenge the code. They will challenge the minutes behind it. Build the log so every billed minute has a date, an actor, an activity, and a place it was captured. Here is the shape that holds up.

Date	Team member	Activity	Contact	Minutes
Mar 03	BH care manager	Intake, PHQ-9 = 17, registry enrollment	face-to-face	25
Mar 07	BH care manager	Care-plan build, patient education call	non-f2f	18
Mar 12	Psychiatric consultant	Weekly caseload review, med recommendation	registry	12
Mar 18	BH care manager	Follow-up, PHQ-9 recheck, coordination w/ PCP	face-to-face	15
Mar 26	BH care manager	Relapse-prevention outreach, symptom tracking	non-f2f	12
Total treatment-team time, March calendar month				82 min → 99492

Calendar month, not rolling 30 daysMinutes reset on the first. Time that crosses month boundaries splits at the boundary, it never carries into the next code.

Each entry names the actor and roleOnly qualified care-manager and consultant time counts. Front-desk or scheduling minutes are not CoCM time and must not be in the total.

Non-face-to-face is billable, and flaggedCare coordination, registry review, and outreach count. Tag them so the auditor sees you knew the difference, not that you blurred it.

Consent captured once, referenced alwaysDocument initiating consent and the once-per-month billing note. Cost-sharing applies, so the consent conversation is part of the record.

Measurement-based care is visiblePHQ-9 and GAD-7 scores logged over time prove the registry is real, not retro-fitted. This is the single strongest audit defense.

The total is derived, not assertedThe billed code should fall out of summed entries automatically. A total that cannot be reconstructed from line items is the first thing a reviewer pulls.

Cite the rules by name

The three authorities this program answers to

CoCM sits at the intersection of a federal payment rule, a federal parity law, and your own state's Medicaid manual. Know which one governs which question.

CMS Physician Fee Schedule

Defines the CoCM codes 99492, 99493, 99494 and the G2214 short-month code, the minute thresholds, and the treating-practitioner billing structure. This is the rule that sets what a minute is worth.

CMS PFS · Psychiatric CoCM

MHPAEA parity requirements

The Mental Health Parity and Addiction Equity Act, with its 2024 final rule on non-quantitative treatment limitations, means BH benefits cannot carry heavier prior-auth or network limits than medical. It is your leverage when a plan under-covers CoCM.

MHPAEA · NQTL final rule

State Medicaid BH manual

Coverage of CoCM under Medicaid is state-specific. Your state behavioral health provider manual sets whether 99492-99494 are payable, which taxonomies qualify, and any state add-on or documentation rule. Read it before your first claim.

State Medicaid provider manual

Where the money actually leaks

Four traps that turn clean work into denials

Billing 99493 in a short month

Under the subsequent-month floor, the claim is not a 99493. It is a G2214. Clinics that never load G2214 simply write the work off.

Counting non-qualified time

Scheduling, records requests, and general front-desk minutes are not care-manager treatment time. Padding the log is the fastest way to lose the whole month on audit.

Missing the psychiatric consultant loop

If there is no documented consultant caseload review, it is care coordination, not CoCM. The specialist input is what makes the model billable.

No measurement-based care in the record

A registry without serial PHQ-9 or GAD-7 scores reads as a spreadsheet. Serial scores are the difference between a program and a billing exercise.

You have the clinical model. We build the machine that gets it paid.
