Outpatient psychotherapy billed correctly, code by code.
Psychiatrists
Medication management (E/M) and add-on psychotherapy codes billed together, correctly.
Mental health billing services: the insurance side, handled
A mental health billing service takes over the insurance side of a behavioral health practice: it confirms coverage, submits claims, follows up on denials and gets clinicians paid by each payer. MCM South does this only for mental and behavioral health. We do not bill for hospital systems, and we do not bill for other specialties.
Most practices outsource for one of three reasons: claims sit unworked, denials pile up, or the clinician is billing at night. Compare the two options in billing software vs. a billing service, or see how to choose a mental health billing company.
Insurance Verification & Eligibility Checks
Active coverage and behavioral-health benefits confirmed before the first session, with carve-outs caught early.

Every denial read for the real reason, fixed where fixable, and appealed where it isn't.
Learn more →05Secondary Claims Billing
Coordination of benefits handled correctly, so secondary payers actually pay their share.
Learn more →06Insurance Credentialing
Getting, and staying, in-network with the payers your patients actually use.
Learn more →07Aging Report
Outstanding claims tracked by how long they have waited, so nothing slips past timely filing.
08Paysheet Report
A paysheet report is a clear record of what each insurance payer paid on your claims, session by session.
At the end of each month, you get the list of every patient whose claim was finalized, with the reimbursement from insurance, along with our billing service invoice.
How our behavioral health billing services fit together
Behavioral health billing services cover every step between a session and a payment. MCM South handles those steps in order, only for psychotherapists and psychiatrists, and only in mental and behavioral health.
| When | What happens | Service | Go deeper |
|---|---|---|---|
| 1Before the first session | Coverage and behavioral-health benefits confirmed, carve-outs caught early | Insurance Verification & Eligibility Checks | |
| 2After the session | Clean claims filed, coded for mental and behavioral health | Electronic Claims Submission | |
| 3For EAP sessions | Employee Assistance Program billing, which runs differently than standard insurance | EAP Billing | |
| 4When a claim comes back | Each denial read for the real reason, fixed where fixable, appealed where it is not | Denied & Rejected Claims Follow-Up and Appeals | |
| 5When a second payer is involved | Coordination of benefits, so secondary payers pay their share | Secondary Claims Billing | |
| 6Before you can bill a payer | Getting, and staying, in-network | Insurance Credentialing |
Professional claims go out on the CMS-1500 form on paper or as an 837P file electronically. CMS explains both in its Medicare Billing: CMS-1500 and 837P booklet. Each payer then adds its own rules, which is why verification and claim follow-up matter.
The right mental health billing services also depend on who you are. Psychotherapists bill outpatient psychotherapy codes. Psychiatrists bill medication management with evaluation and management (E/M) codes plus add-on psychotherapy codes. Our CPT & E/M Code Guide covers both, and the billing terms glossary defines the terms. See who we serve, or book a free consultation. Not sure which service to start with?

Billing software stores your claims and sends them. A billing service has people who work the claims, denials and appeals for you. See billing software vs. a billing service.

Credentialing is one of the six services. It is separate from claim billing, because you must be enrolled with a payer before claims to that payer can pay. Ask about credentialing.
