How to Submit a Superbill to CareFirst BlueCross BlueShield

CareFirst BlueCross BlueShield is the dominant health insurer in the Washington DC, Maryland, and Northern Virginia region. Submitting an OON therapy superbill to CareFirst is a well-supported process with strong mental health benefits in this area.

Overview: CareFirst and Out-of-Network Mental Health Benefits

CareFirst BlueCross BlueShield is a BCBS affiliate serving the DC metro region. Most CareFirst commercial (employer-sponsored) and individual plans include OON mental health benefits, subject to an OON deductible and coinsurance. Maryland law includes strong mental health parity enforcement, giving CareFirst members additional protections when it comes to behavioral health coverage.

CareFirst processes OON behavioral health claims through its standard claims department. Most plans do not require a referral for OON mental health services under PPO plans, but HMO members should verify network requirements before scheduling with an OON therapist. For more context on the general process, see our step-by-step superbill submission guide. For a full overview of CareFirst coverage, visit our CareFirst insurance guide.

CareFirst's online portal at carefirst.com provides a Member Login where you can submit claims, track status, and view EOBs — making it one of the more streamlined OON submission experiences among regional carriers.

Step-by-Step Process for Submitting to CareFirst

1. Get your superbill from your therapist. Request a superbill covering all sessions you want to submit. CareFirst accepts batch submissions covering multiple dates of service on one claim.
2. Log in to your CareFirst member account. Go to carefirst.com and sign in with your Member Login credentials. Navigate to Claims and select Submit a Claim. This is the fastest and most reliable method.
3. Complete the online claim form. CareFirst will ask for provider name, dates of service, CPT codes, and amounts charged. Upload the superbill PDF as supporting documentation.
4. Alternative: mail your claim. If you prefer paper, download the CareFirst OON claim form from carefirst.com and mail it, along with your superbill, to the claims address on your ID card. Use certified mail for your records.
5. Note your confirmation number. After online submission, screenshot the confirmation page. After mailing, retain the certified mail receipt.

What to Include With Your CareFirst Claim

CareFirst requires the superbill to contain all required superbill fields. Specifically for CareFirst, confirm your superbill includes:

• Provider full name, NPI (Type 1), and practice address
• Provider Tax ID (EIN or SSN) and professional license number
• Your name, date of birth, and CareFirst member ID number
• Date(s) of service
• CPT procedure code (e.g., 90837 for 60-minute therapy) and description
• ICD-10 diagnosis code (e.g., F41.1 for generalized anxiety)
• Place of service code (11 for office; 10 for telehealth)
• Fee charged per session and amount you have already paid

CareFirst's Processing Timeline

CareFirst typically processes OON mental health claims within 30–45 days of receipt. Online submissions are received immediately; mailed claims add several days for postal transit. You will receive an Explanation of Benefits (EOB) in your CareFirst portal before any payment is issued. Payment arrives by check or direct deposit if configured.

CareFirst's filing deadline for most commercial plans is 180 days from the date of service. Submit promptly to avoid deadline issues.

Common Issues When Submitting to CareFirst

• HMO plan limitations: CareFirst HMO members generally cannot receive OON reimbursement for routine outpatient therapy. Verify your plan type (PPO vs. HMO) before submitting.
• Missing NPI: CareFirst will reject claims without a valid provider NPI. Confirm your therapist's NPI is Type 1 (individual) and matches the NPI Registry.
• Regional plan variations: CareFirst serves DC, Maryland, and Northern Virginia with some plan variations by state. DC and Virginia members may have slightly different portal steps than Maryland members.
• Duplicate submission: Submitting online and by mail for the same dates of service will create a duplicate and delay processing. Choose one method.

Tips for a Smooth CareFirst Claim

• Call Member Services before your first claim to verify OON deductible, coinsurance rate, and whether CareFirst requires their own claim form in addition to the superbill.
• Use the CareFirst member portal to track claim status. Claims appear within a few business days of online submission.
• If your claim is denied, Maryland's strong mental health parity laws give you robust appeal rights. Maryland Insurance Administration can assist if internal appeals fail.
• Submit monthly in batches rather than after every session to reduce administrative overhead.

Superbilled makes it easy to generate CareFirst-ready superbills with all required fields pre-filled. Once your therapist sends you the superbill, you can submit directly to CareFirst through the carefirst.com portal or by mail using the steps above.
