From time to time, we receive questions from the field that we know impact many behavioral health provider groups.  We recently received the following question from a behavioral health provider:

“Our organization offers a chemical dependency IOP program and has several clients covered by commercial insurance plans. We verify benefits, obtain authorizations, and provide the services. However, when claims are paid, reimbursement is often only $28-$40 per IOP day. We bill these services the same way we bill our Medicaid IOP clients using H0015. Why are the commercial payers paying so much less than Medicaid?”

The answer is often a combination of billing methodology and contract structure.

Many commercial insurance companies require Intensive Outpatient Program (IOP), Partial Hospitalization Program (PHP), and Ambulatory Detox services to be billed on a UB-04 facility claim using specific revenue codes and HCPCS codes rather than through traditional professional claim submission processes.

However, the larger issue is frequently contractual.

Many commercial payers require a separate facility agreement, institutional agreement, or service-specific contract before they will reimburse higher levels of care appropriately. Simply being credentialed or participating with a payer does not necessarily mean that IOP services are covered under the existing reimbursement agreement.

As a result, organizations may be obtaining authorizations, delivering services, and submitting clean claims, yet still receiving reimbursement that does not reflect the actual level of care being provided.

Signs You May Have a Contracting Issue

• IOP claims are being paid, but reimbursement appears significantly lower than expected.
• Authorizations are approved, yet payments do not align with the intensity of services delivered.
• Internal billing reviews identify no significant coding or claim submission errors.
• Staff members are uncertain whether IOP services are specifically included within payer agreements.
• The organization is billing IOP services the same way it bills outpatient therapy services.

Questions to Ask

• Are all levels of care specifically addressed within your current payer contracts?
• Does your organization have the appropriate facility or institutional agreements in place?
• Are IOP services reimbursed under a separate fee schedule or methodology?
• Have payer requirements changed since the program was initially contracted?
• Are claims being submitted on the correct claim form with the appropriate billing structure?

Contracting Matters

One of the most common misconceptions in behavioral health is that obtaining authorization guarantees appropriate reimbursement. In reality, authorization only confirms medical necessity.  Authorization does not determine reimbursement. Your contract does.

Organizations that expand services without reviewing their payer agreements often discover that reimbursement methodologies do not support the operational requirements of the program.

At G&M Consulting, we have more than 44 years of managed care experience helping behavioral health organizations navigate payer contracting, facility agreements, reimbursement strategy, and operational readiness.

If your organization is experiencing reimbursement challenges, evaluating new levels of care, or reviewing existing payer agreements, we would welcome the opportunity to help identify potential gaps and opportunities.
