CO-242: Not provided by required network provider

The payer is telling you the member's benefit only covers the service when it is rendered by a required provider type, usually an in-network clinician or the member's assigned primary provider. The claim hit a network or primary-care gatekeeper rule and the payer priced the line or claim at zero under your contract. Mechanically, the plan's edit compares the billing or rendering NPI and taxonomy against the member's network tier or PCP assignment on the date of service. When it fails, the payer applies CO-242 and moves the denied amount into contractual adjustment, which you must write off unless you can correct to a valid, covered provider.

In behavioral health, this often appears when a non-participating therapist or facility bills under their own NPI on a member whose mental health benefit is restricted to a specific network or carve out vendor. Example: a residential SUD facility is not contracted with the behavioral carve out, bills per diem on a UB-04, and the payer applies CO-242 because only contracted facilities can provide that level of care. You also see this when a plan requires members to receive behavioral health through a designated group or IPA and your independent clinician bills directly. For instance, an IOP program bills group therapy under a rendering NPI that is not on the payer's network file for that tax ID, so the entire IOP authorization sits unused and claims deny under CO-242. Telehealth brings another twist: some plans only recognize certain in-network virtual providers or specific contracted telehealth platforms. If your PHP psychiatrist provides telehealth medication management but the contract ties telehealth to a separate entity or limits it to the PCP, the payer can deny the visit under CO-242, and the per-visit charge becomes a contractual loss if not corrected.

• Confirm whether the billing and rendering NPIs are actually in network for the member's behavioral health plan or carve out on the date of service.
• Verify if the member is required to see a designated PCP, group, or behavioral network and check whether that provider was involved or can be reported.
• If the wrong NPI or taxonomy was billed for a contracted provider, correct the billing or rendering provider details and submit a corrected claim.
• If another in-network clinician in your program actually saw the patient, rebill with the accurate rendering provider and matching documentation.
• When the member saw you out of network but has any out-of-network benefit, ask the payer if CO-242 is appropriate and appeal if plan documents show coverage.
• If the member truly has no benefit with you as a provider, adjust off the CO-242 amount per contract and update your scheduling and financial consent notes so staff do not treat as in network next time.

• Run eligibility and benefit checks before admission or the first session, including behavioral health carve outs and network status for each rendering provider.
• Maintain an internal provider roster that matches payer credentialing data, and scrub claims to stop any line with an out-of-network or inactive NPI for that plan.
• Train front desk and intake staff to route members to in-network clinicians within your program when a plan limits behavioral services to specific providers.
• Review payer contracts and provider manuals for rules about PCP referral or designated behavioral networks and build those checks into your scheduling and authorization workflows.
