Who Can Bill Medicare for Mental Health Services?

Eligible Provider Types

Medicare recognizes these mental health provider types for direct billing:

Important: LPCs and LMFTs were added to Medicare in 2024 under the Bipartisan Budget Act. Check CMS guidance for current enrollment procedures.

Medicare Enrollment Process

Before billing Medicare, you must enroll through PECOS (Provider Enrollment, Chain, and Ownership System).

Step 1: Get Your NPI

Apply at NPPES if you don't have one.

Step 2: Enroll in PECOS

1. Create an Identity & Access Management (I&A) account
2. Complete the CMS-855I application (individual providers)
3. Submit required documentation
4. Wait for approval (60-90 days typically)

Step 3: Opt-In or Opt-Out Decision

You must choose one:

Participating Provider: Accept Medicare assignment on all claims (recommended for most)

• Payment goes directly to you
• Receive 5% higher fee schedule rates
• Listed in Medicare provider directory

Non-Participating Provider: Decide claim-by-claim whether to accept assignment

• May collect up to 115% of fee schedule from patients
• More administrative complexity

Opt-Out: Do not participate in Medicare at all

• Can only see Medicare beneficiaries under private contracts
• Must file affidavit with Medicare
• Patients cannot submit claims for reimbursement

Step 4: Revalidation

Medicare requires revalidation every 5 years. Mark your calendar and respond promptly to revalidation requests.

Covered Mental Health Services

Outpatient Services

• Psychiatric evaluations (90791, 90792)
• Group therapy
• Most mental health services

For telehealth details, see our telehealth guide.

Services NOT Covered

Medicare does not cover:

• Custodial care
• Experimental treatments
• Services not deemed medically necessary
• Routine counseling without diagnosis

Medicare Payment Rules

Assignment

When you accept assignment:

• Medicare pays 80% of the allowed amount directly to you
• Patient pays 20% coinsurance
• You cannot bill above the Medicare fee schedule

Deductible

Patients must meet the Part B annual deductible before Medicare pays (2026: ~$250).

The Medicare Fee Schedule

Medicare rates are based on:

• Relative Value Units (RVUs): Work, practice expense, malpractice
• Conversion Factor: Dollar value per RVU (~$33 in 2026)
• Geographic Adjustment (GPCI): Local cost variations

Use the CMS Fee Schedule Look-Up Tool for exact rates in your area.

Documentation Requirements

Medicare requires documentation supporting medical necessity. For mental health services, this includes:

For Each Session

• Date, start/end times, duration
• Services provided (intervention types)
• Patient's response to treatment
• Progress toward treatment goals
• Plan for next session

Treatment Plan Requirements

• Diagnosis with ICD-10 code
• Presenting problems and symptoms
• Treatment goals (measurable, time-limited)
• Planned interventions
• Expected frequency and duration
• Signature and date

For documentation best practices, see our SOAP notes guide.

Medicare Advantage Plans

About 50% of Medicare beneficiaries are enrolled in Medicare Advantage (Part C) plans—private insurance alternatives to traditional Medicare.

Key Differences

Tips for MA Plans

• Verify the patient's specific plan
• Check if you're in-network for that plan
• Confirm authorization requirements
• Bill the MA plan, not Medicare directly

Common Medicare Billing Mistakes

Mistake 1: Billing Incident-To Incorrectly

"Incident-to" billing allows certain services by auxiliary personnel to be billed under the physician's NPI at full rates.

Rules for incident-to:

• Physician must be present in the office suite
• Initial service must have been provided by physician
• Physician must maintain active involvement

Mental health exception: Most licensed mental health providers bill independently, not incident-to.

Mistake 2: Time Documentation Errors

Medicare auditors look closely at time-based codes. Always document:

• Start and end times, OR
• Total face-to-face time

Mistake 3: Missing Modifiers

Common required modifiers:

• 95: Synchronous telehealth
• 93: Audio-only telehealth
• AH: Clinical psychologist
• AJ: Clinical social worker

Mistake 4: Incorrect Place of Service

Mistake 5: Billing for Non-Covered Services

Medicare doesn't cover:

• Missed appointments (no-show fees)
• Phone calls (except authorized telehealth)
• Report writing time
• Travel time

Medicare Annual Wellness Visit (AWV)

As of 2024, depression screening is a required element of the Annual Wellness Visit. Mental health providers can partner with primary care to provide follow-up services for positive screens.
