What does a CO-242 referral required denial mean?

CO-242 (services not provided by network or primary care providers) indicates that your health plan requires care to be delivered or coordinated through your network or primary care physician, for example a referral authorization from your primary care physician before the plan will pay for a specialist visit or procedure. Your claim was denied because this referral was not in place when the service was rendered. This is most common in HMO plans but can also appear in some PPO and EPO plans for specific service types.

Can I get a retroactive referral from my doctor?

In many cases, yes. Contact your PCP's office and explain the situation. Ask them to submit a retroactive referral or authorization to the insurer covering the service date. Many insurers allow retroactive referrals within a specified window (typically 30-90 days) if the service was clinically appropriate and there is a documented clinical relationship between the PCP and specialist. The PCP's office should submit this directly to the insurer.

Are there services that don't require a referral even in HMO plans?

Yes. Federal law and most state regulations require HMO plans to allow direct access to: (1) OB/GYN services for routine and preventive gynecological care; (2) emergency and urgent care; (3) pediatric preventive care; (4) certain mental health and substance use disorder services. Many plans also allow direct access to dermatology or optometry. Check your Summary of Benefits and Coverage for your plan's specific self-referral exceptions.

What if I was traveling and needed emergency specialist care?

Emergency care never requires prior authorization or a referral. If your specialist visit was necessitated by an emergency medical condition, the insurer cannot require a referral as a condition of coverage. Document the emergency nature of the visit with the medical records, and cite federal and state emergency care provisions in your appeal.

What is continuity of care and how can it help with a referral denial?

Continuity of care provisions require your insurer to cover ongoing treatment with an out-of-network or non-referred provider when switching plans or networks would disrupt active treatment. If you recently changed insurance plans and your prior plan covered a specialist without referral, request a continuity of care exception and provide documentation of the ongoing treatment relationship.

How to Appeal a 'Referral Required' Insurance Denial (CO-242)

Insurance denied your specialist visit because you didn't have a referral (CO-242)? Retroactive referrals, emergency exceptions, and HMO rules can often reverse this denial. Learn how to fight back.

What does CO-242 mean?

A CO-242 denial means your insurer is requiring care to be provided by an in-network or primary care provider, typically a referral from your primary care physician (PCP) before they will cover the specialist visit or service you received. Referral requirements are most common in HMO and some EPO plans. The denial typically means either no referral was obtained, the referral was for a different service than what was provided, or the referral authorization had expired.

Why insurers issue CO-242 denials

HMO plans use PCP gatekeeping and referral requirements as a cost-control mechanism - the PCP coordinates all specialty care and must approve referrals before the patient sees a specialist. When patients bypass this process (often out of convenience or in urgent situations), the specialist visit may be denied. However, referral denials can also result from coordination errors between the PCP's office and specialist's billing department.

Appeal strategy

Contact your PCP's office immediately and request a retroactive referral. Many insurers allow retroactive referral requests within 30-90 days of the service date when there is a valid clinical reason. If the service was urgent and waiting for a referral would have delayed necessary care, document this in your appeal. If your plan covers direct access to OB/GYN or mental health specialists without a referral, cite these exceptions. Check your plan's 'continuity of care' provisions if you recently switched plans.
