EAP Billing for Therapists and Psychiatrists, Handled Correctly
EAP billing is how a provider gets paid for counseling sessions funded through an employee assistance program (EAP), an employer-paid benefit that runs separately from the client's health insurance.
MCM South Medical Billing Service processes EAP claims for psychotherapists and psychiatrists. EAP vendors each have their own forms, codes and authorization steps, and a claim sent the insurance way is often a claim paid late or not at all.
Who this is for
- Therapists who see EAP referrals and are not sure how to bill them
- Group practices that bill EAP sessions through several vendors
- Psychiatrists whose clients arrive through an employer program
- Office managers handling EAP authorization numbers and vendor forms
What is an employee assistance program?
An employee assistance program is a workplace service that helps employers address productivity issues and helps employees identify and resolve personal concerns, through short-term counseling, assessment and referral.
The Employee Assistance Professionals Association (EAPA) lists short-term intervention and referral for diagnosis, treatment and follow-up among the core components of an EAP (EAPA, checked 10/1/26). The U.S. Office of Personnel Management describes the federal EAP as free, voluntary and confidential, with initial assessment and short-term counseling at no cost, often extended to immediate family, plus referrals for further services (OPM, checked 10/1/26). The U.S. Department of Labor describes EAPs as typically offering short-term mental health or substance abuse counseling or referral, along with financial and legal services (DOL release, checked 10/1/26).
The billing takeaway. An EAP is not health insurance. It is an employer-funded program run by a vendor, and the vendor, not the client's insurer, decides how you enroll, get authorized and get paid.
EAP billing is the process of filing claims for counseling sessions that an employee assistance program authorizes. It differs from billing a health plan because the EAP vendor sets the rules.
How EAP billing differs from insurance billing
EAP billing differs from insurance billing in who pays, what the client owes, how sessions are authorized, and which form or portal the claim goes through.
| Health insurance | EAP | |
|---|---|---|
| Who pays | The insurer, under the client's plan | The employer's program, through an EAP vendor |
| Client cost | Deductible, copay or coinsurance may apply | Cigna's provider guide says EAP providers collect no out-of-pocket expenses or copayments. OPM says the federal EAP counseling consultation is free. |
| Authorization | Eligibility check, and prior authorization for some services | An EAP code or authorization from the vendor before the first session (Cigna guide); a case form when sessions are preauthorized (Carelon FAQ) |
| Session count | Set by the plan's benefits | Set by the employer's EAP plan, so it varies by employer |
| Claim path | 837P or CMS-1500 to the payer | Often a vendor form or portal. It differs by vendor. |
| Network | Credentialed with the payer | Usually enrolled with the EAP vendor. Each vendor has its own process. |
When EAP sessions run out, the client may continue under their health insurance. Verify that coverage before the next session. See our eligibility terms and authorization terms.
What EAP vendors say in their own provider materials
These are examples from the vendors' provider pages, checked 10/1/26. Several of these documents show no date, so confirm the current version before you bill.
| EAP vendor | What the provider material says |
|---|---|
| Cigna / Evernorth | All EAP claims are billed with CPT code 99404. Employer-referred clients must get an EAP code from Cigna and give it to you before the first session. Self-referring clients get a code online. The guide describes assess-and-refer as one to three face-to-face sessions and short-term counseling programs of five to eight sessions, extendable up to twelve. Treat those as Cigna's figures, not universal ones. |
| Carelon Behavioral Health | The CAF-1 case activity and billing form is for EAP affiliates when services are preauthorized. The CAF-2 is for onsite EAPs and services that were not preauthorized. Submission is through ProviderConnect or by fax. |
| Magellan | To be paid for EAP services you must complete and submit the Employee Assistance Service Information (EASI) form. |
| ComPsych | Providers apply with the Prospective Provider Interest Form. Once enrolled, they can log claims, check claim status, submit discharge information and request extensions of referral end dates. |
| Anthem EAP | Providers apply through the Carelon Behavioral Health combined network and should update their CAQH profile. EAP claims questions go to the Anthem EAP claims mailbox listed on the page. |
Vendors change forms, codes and portals. This table is a starting point, not a billing manual. Never assume one vendor's rules apply to another. For general network enrollment, see our credentialing page.
Each EAP vendor sets its own EAP billing rules, forms and authorization steps. Read the vendor's provider manual before you file the first session. Our billing terms glossary explains the terms you will see.
Where EAP claims go wrong
- Billed to insurance instead of the EAP. The claim can deny because the sessions were authorized under the EAP, not the client's insurance.
- No authorization or EAP code. Vendors such as Cigna require the code before the first session.
- Wrong form or portal. Carelon, Magellan and ComPsych each use their own process, so an 837P to the wrong place goes nowhere.
- Sessions beyond the authorization. The employer's plan sets the cap. Billing past it means the sessions are unpaid, so track authorized visits.
- Collecting a copay the program does not allow. Cigna's guide says EAP providers collect no out-of-pocket amounts. Check each vendor's rule.
- Not enrolled with the vendor. Several vendors require you to apply to their network before you see their referrals.
For code and modifier questions on any claim, use our CPT and E/M code guide.
Many EAP billing problems start with a missing authorization number or a session that goes past what the EAP approved. Check both before you submit. Clean electronic claims submission helps with the rest.
Psychotherapists and psychiatrists and EAP work
Psychotherapists
EAP programs center on assessment, short-term counseling and referral, so most EAP sessions are therapy sessions. Track the authorized session count and the vendor's form for each referral. See individual psychotherapy codes.
Psychiatrists
Because EAPs focus on short-term counseling and referral, medication management visits usually bill to the client's health insurance, not the EAP. Confirm what the vendor covers before you bill. See E/M codes and psychotherapy add-on codes.
For psychotherapists and psychiatrists alike, EAP billing starts with the vendor's authorization. See our Who We Serve page for the practices MCM South works with.
Rules differ by EAP and by who sponsors it
Employer-sponsored EAPs (vendor contracts)
The vendor's provider agreement and manual control enrollment, authorization, forms and rates. They differ by vendor and by employer plan. Treat the vendor's own documents as the source of truth.
Federal employee EAPs
OPM describes the federal EAP as free, voluntary and confidential, with short-term counseling at no cost to the employee. For billing details, ask the EAP vendor your client's agency uses.
State rules
EAP billing is mostly set by vendor contract and employer plan, not by state Medicaid or state insurance rules. Where a state law affects a referral or a client's coverage after EAP sessions end, it varies by state. Do not apply one state's rule to another.
EAP billing rules vary by vendor and by plan, so confirm the current rules with the vendor before you rely on them.

- Authorization numbers and session counts tracked per client
- EAP and insurance claims kept apart
- Denied or rejected EAP claims followed up and appealed

EAP billing FAQ
How do I get paid for EAP sessions as a therapist?
You usually have to enroll with the EAP vendor, receive an authorization or EAP code for each referral, and submit the claim the way that vendor requires. Each vendor sets its own forms and portals. Cigna, Carelon, Magellan and ComPsych all publish different provider instructions.
Do I bill an EAP on a CMS-1500 or through the vendor's portal?
It depends on the vendor. Carelon uses its CAF forms, Magellan uses the EASI form, ComPsych offers a provider portal, and Cigna's guide says to bill CPT code 99404. Because each vendor sets its own claim path, confirm it with the vendor before you bill.
What is an EAP authorization or case number?
It is the code or authorization the vendor issues for an employee's referral. In Cigna's guide, employer-referred clients must get an EAP code and give it to the provider before the first counseling session. Where the number goes on the claim depends on the vendor.
How many EAP sessions does a client get, and what happens after they run out?
The employer's plan sets the number, so it varies. Cigna's guide describes short-term programs of five to eight sessions, extendable up to twelve, but that is one vendor's structure. After the sessions end, the client may continue under their health insurance, which you should verify.
Do I need to be credentialed with an EAP vendor to see its clients?
Usually you need to enroll with the vendor. Carelon Behavioral Health takes applications through its Payer Space in Availity, and ComPsych takes a provider interest form. The enrollment path differs by vendor, so apply to each one directly.
