Required Fields on a Superbill: The Complete Checklist

Insurance companies reject superbills that are missing required fields. Here is the complete checklist — with an explanation of why each field matters.

Provider Fields

• Full legal name or practice name — must match your NPI registration
• NPI number — 10-digit National Provider Identifier, required for all claims
• Tax ID / EIN — for payment routing
• License number and state — e.g., LCSW-12345, CA
• Taxonomy code — 10-character code identifying your provider specialty
• Practice address and phone number
• Provider signature

Patient Fields

• Patient full name
• Date of birth
• Insurance member ID

Service Fields

• Date of service — must be exact, not a range
• CPT code — procedure code (e.g., 90837 for 60-min psychotherapy)
• ICD-10 code — diagnosis code (e.g., F41.1 for generalized anxiety)
• Fee charged — your full rate, not the discounted amount
• Amount paid — what the patient actually paid
• Place of service code — 11 (office) or 02 (telehealth)
