Behavioral health claims often fail for reasons that trace back to steps completed before a service is rendered: coverage that runs through a separate behavioral health carve-out, benefits never verified against the specific plan, authorizations that do not match the units billed, documentation that does not support medical necessity, or confidentiality rules that constrain what may be disclosed. This checklist organizes those pre-submission steps into discrete items a billing team can work through for each encounter. Because behavioral health coverage rules differ substantially by payer, plan, state Medicaid program, and federal program, each item flags where variation applies and points to the governing source (CMS at cms.gov, Medicaid.gov, SAMHSA at samhsa.gov, and CMS Medicare Learning Network materials) rather than asserting a universal rule. It is a neutral educational tool, not advice about any specific payer relationship.
Confirm active coverage and identify any behavioral health carve-out Verify that coverage is active for the date of service and determine whether behavioral health benefits are administered by the medical plan or by a separate behavioral health carve-out (a managed behavioral health organization). When a carve-out applies, eligibility, authorization, and claim routing may differ from the medical plan, and claims sent to the wrong payer are commonly rejected. See eligibility verification (/knowledge-base/eligibility-verification), behavioral health eligibility and carve-outs (/knowledge-base/behavioral-health-billing/behavioral-health-eligibility-and-carve-outs), and the glossary terms eligibility verification (/resources/glossary/eligibility-verification) and behavioral health carve-out (/resources/glossary/behavioral-health-carve-out). Coverage structure varies by payer, plan, and state. Verify behavioral health benefits and note parity context Confirm the specific behavioral health benefits, cost-share, visit or day structures, and any plan limitations for the service being provided; benefit verification is distinct from confirming eligibility. Federal mental health parity requirements govern how certain plans may apply limitations to behavioral health relative to medical/surgical benefits, but application varies by plan type and is enforced through specific rules rather than a single universal standard (see hhs.gov and cms.gov). Reference behavioral health parity (/knowledge-base/behavioral-health-billing/behavioral-health-parity) and the glossary term mental health parity (/resources/glossary/mental-health-parity). Determine and secure any required prior authorization Identify whether the service requires prior authorization and, if so, confirm it is obtained before or within the payer's allowed window, capturing the authorization number and the approved units, dates, and level of care. Requirements differ by payer, plan, program, and service (for example, higher levels of care such as intensive outpatient or PHP frequently involve authorization). See behavioral health prior authorization (/knowledge-base/behavioral-health-billing/behavioral-health-prior-authorization), prior authorization (/knowledge-base/prior-authorization), and the glossary terms prior authorization (/resources/glossary/prior-authorization) and authorization-number (/resources/glossary/authorization-number). Reconcile authorized units and level of care to what will be billed Ensure the units, dates, provider, and level of care on the authorization match the service actually rendered and the claim to be submitted; mismatches between authorized and billed units are a frequent, preventable denial source. This is especially relevant for time-based psychotherapy, group therapy, and program-based services. See psychotherapy time-based billing (/knowledge-base/behavioral-health-billing/psychotherapy-time-based-billing), billing intensive outpatient and PHP (/knowledge-base/behavioral-health-billing/billing-intensive-outpatient-and-php), and matching authorized units to billed services (/knowledge-base/prior-authorization/matching-authorized-units-to-billed-services). Confirm documentation supports the service and medical necessity Verify the record includes the elements payers expect for the service billed (for example, session start/stop or total time for time-based psychotherapy, group participation details, or the components of an evaluation), and that documentation supports medical necessity for the coverage in question. Specific documentation and medical-necessity criteria vary by payer, plan, and program and are defined in payer policy and, for Medicare, in coverage determinations (cms.gov). See behavioral health documentation requirements (/knowledge-base/behavioral-health-billing/behavioral-health-documentation-requirements) and the glossary term medical necessity (/resources/glossary/medical-necessity). Select the appropriate code family and unit basis Confirm the encounter maps to the correct behavioral health code set and unit basis (for example, time-based psychotherapy, evaluation and management, group therapy, or program/level-of-care codes), including any modifiers the payer requires. Describe concepts and name the maintained code sets rather than assuming code specifics, since payer rules and accepted modifiers vary. See behavioral health code families (/knowledge-base/behavioral-health-billing/behavioral-health-code-families), evaluation and management in behavioral health (/knowledge-base/behavioral-health-billing/evaluation-and-management-in-behavioral-health), and billing for group therapy (/knowledge-base/behavioral-health-billing/billing-for-group-therapy). Confirm the rendering provider is enrolled and eligible to bill Verify the rendering clinician's enrollment and network status supports billing for the service under the payer in question; which behavioral health provider types are recognized and reimbursable varies by payer, plan, and program, and by Medicare and each state Medicaid program (cms.gov, medicaid.gov). Enrollment or credentialing gaps produce denials unrelated to the clinical service. See credentialing (/knowledge-base/credentialing), behavioral health under Medicare (/knowledge-base/behavioral-health-billing/behavioral-health-under-medicare), and behavioral health under Medicaid (/knowledge-base/behavioral-health-billing/behavioral-health-under-medicaid). Set the correct place of service and telehealth indicators Confirm the place of service and any telehealth indicators or modifiers reflect where and how the service was delivered. Telehealth coverage, eligible modalities, and required indicators for behavioral health vary by payer, plan, program, and effective date, and Medicare telehealth policy is subject to change (see cms.gov). See behavioral health place of service and telehealth (/knowledge-base/behavioral-health-billing/behavioral-health-place-of-service-and-telehealth), place of service code lookup (/tools/lookup/place-of-service-code-lookup), and eligibility checks for telehealth (/knowledge-base/eligibility-verification/eligibility-checks-for-telehealth). Apply confidentiality rules, including 42 CFR Part 2 where applicable Where records are covered by the federal confidentiality regulation for substance use disorder treatment (42 CFR Part 2), confirm that any consent and disclosure requirements are met before information is released, in addition to general privacy obligations. Whether Part 2 applies depends on the program and record type; consult SAMHSA (samhsa.gov) and HHS (hhs.gov). See confidentiality and 42 CFR Part 2 (/knowledge-base/behavioral-health-billing/confidentiality-and-42-cfr-part-2), substance use disorder billing (/knowledge-base/behavioral-health-billing/substance-use-disorder-billing), and the glossary term 42 CFR Part 2 (/resources/glossary/42-cfr-part-2). Resolve coordination of benefits before submission Identify whether more than one payer is responsible and determine the correct order so the claim goes to the primary payer first, with secondary billing prepared as needed; this includes situations involving a behavioral health carve-out alongside a medical plan. Order-of-benefits rules vary by coverage type and situation. See identifying primary and secondary coverage (/knowledge-base/eligibility-verification/identifying-primary-and-secondary-coverage), secondary billing (/knowledge-base/payments-and-posting/secondary-billing), and the glossary term coordination of benefits (/resources/glossary/coordination-of-benefits). Confirm the claim is within the timely filing window Verify the claim will be submitted within the applicable timely filing deadline, which is set by each payer and, for public programs, by Medicare and each state Medicaid program (cms.gov, medicaid.gov); deadlines are not universal and missing them is a common cause of non-payment. See medicare timely filing (/knowledge-base/medicare-billing/medicare-timely-filing), medicaid timely filing (/knowledge-base/medicaid-billing/medicaid-timely-filing), and the glossary term timely filing (/resources/glossary/timely-filing).
