How To Submit Claims To UnitedHealthcare

For UnitedHealthcare, the practical claims workflow usually starts with electronic submission guidance and only falls back to paper instructions when the payer documents a mailing address for specific claim types or exceptions. The details below keep the workflow broad instead of reducing it to a single address.

At a glance

• UnitedHealthcare supports claims submission through the Provider Portal, EDI, API, and paper/mail for some scenarios. Official guidance emphasizes digital submission where available, with portal tools for claims, claims status, corrections, and document exchange. Corrected claims may be submitted electronically or on paper, and the official guidance says to use frequency code 7 for corrected claims.

• Paper/mailed claim addresses are not consolidated in the sources reviewed and may vary by line of business and state.
• Some Community Plan workflows have digital submission requirements and market-specific transitions.
