CPT 90834 45-Minute Psychotherapy Denied by Molina Healthcare? Appeal Guide & Letter Template

Why Molina Healthcare Denies CPT 90834 (Psychotherapy 45 Minutes)

Molina Healthcare denies CPT 90834 claims for several documented reasons. Understanding the specific denial reason on your Explanation of Benefits (EOB) is the critical first step before writing your appeal.

Common Denial Reasons for CPT 90834

Medical Necessity Not Established (CO-50, CO-236)
Molina determines that 45-minute psychotherapy does not meet their internal clinical criteria for your diagnosis. For mental health services, Molina requires documentation of the mental health diagnosis, treatment plan with measurable goals, evidence that the level of care is appropriate for the severity of the condition, and compliance with Mental Health Parity and Addiction Equity Act (MHPAEA) requirements. Denials that apply stricter criteria than comparable medical/surgical benefits may violate parity law.

Prior Authorization Not Obtained (CO-15, CO-197)
Most Molina plans require prior authorization for CPT 90834 (Psychotherapy 45 Minutes). If the procedure was performed without prior auth, the claim will be denied regardless of medical necessity. However, you may be able to obtain retroactive authorization, especially if the service was urgent or medically necessary. Check your specific plan's policies on retro-auth at molinahealthcare.com/providers.

Conservative Treatment Not Exhausted (CO-50)
Molina requires documentation of conservative treatment before approving 45-minute psychotherapy. The specific requirements vary by procedure type and plan. Review the applicable medical policy and document all prior treatments with dates and outcomes.

Documentation Insufficient (CO-16, CO-252)
Clinical documentation submitted does not support the medical necessity for 45-minute psychotherapy. Molina requires specific elements that demonstrate the procedure meets their coverage criteria.

Step-by-Step: How to Appeal a CPT 90834 Denial from Molina Healthcare

Step 1: Identify the Exact Denial Reason

Read your EOB or remittance advice carefully. Look for:

• CARC (Claim Adjustment Reason Code): CO-50, CO-15, CO-16, CO-197, CO-236, PR-96


• RARC (Remittance Advice Remark Code): N657, N56, MA130


• Molina-specific denial code or policy reference number

If the denial letter references a specific Molina medical policy number, request a copy of that policy. You are legally entitled to this under ERISA §503 (employer plans) or ACA §2719 (individual/marketplace plans).

Step 2: Review Molina Healthcare's Coverage Criteria

Molina publishes clinical guidelines at molinahealthcare.com/providers. For Medicaid managed care members, also check your state Medicaid program's coverage policies, as Molina may follow state Medicaid criteria for certain services.

Compare the criteria point-by-point against your clinical documentation. Identify exactly which criterion Molina claims was not met.

Step 3: Gather Supporting Documentation

For a CPT 90834 appeal, you will need:

• Denial letter/EOB with the specific denial reason and any policy reference numbers


• Clinical notes from the ordering/performing physician documenting the indication for CPT 90834


• Physician letter of medical necessity addressing the specific criteria Molina cited


• Psychiatric evaluation or psychological assessment


• Treatment plan with measurable goals


• Progress notes documenting symptoms, treatment response, and functional status


• GAF or PHQ-9/GAD-7 scores showing severity


• MHPAEA compliance documentation if parity concerns exist

Step 4: Write Your Appeal Letter

Your appeal letter should include:

• Patient demographics and claim reference numbers (claim #, date of service, member ID)


• Specific denial reason quoted from the EOB


• Point-by-point rebuttal addressing each criterion Molina cited


• Clinical evidence supporting medical necessity for 45-minute psychotherapy


• Peer-reviewed citations from relevant specialty society guidelines


• Request for specific action — approval of CPT 90834 and reprocessing of the claim

Pro tips for CPT 90834 appeals to Molina Healthcare:

• Quote Molina's own medical policy criteria and show how each criterion IS met


• Reference peer-reviewed literature supporting medical necessity for 45-minute psychotherapy


• Include relevant specialty society guidelines (these carry significant weight)


• Address the specific denial reason directly — do not write a generic appeal


• If the denial was based on "insufficient documentation," submit the missing documentation with a cover letter explaining what was added


• Keep the letter to 1-2 pages maximum — reviewers process hundreds of appeals

Step 5: Submit the Appeal Within the Deadline

| Appeal Detail | Molina Healthcare |
|--------------|---------------|
| Appeal Window | Typically 60-180 days; varies by plan type and state |
| Submit Appeals To | Varies by state — check provider portal or member ID card |
| Appeals Fax | Varies by state |
| Provider Portal | molinahealthcare.com/providers |

Important: Always send appeals via certified mail or fax with confirmation. Keep copies of everything.

Step 6: Request a Peer-to-Peer Review

For CPT 90834 denials based on medical necessity, request a peer-to-peer review between the ordering/performing physician and Molina's medical director. This is often the most effective intervention — many denials are overturned during peer-to-peer without a formal written appeal.
