CMS-1500 Boxes 12 and 13: Patient and Insured Signatures

A practical guide to completing Boxes 12 and 13: Patient and Insured Signatures accurately and consistently.

From our workflow: When reviewing Patient and Insured Signatures, we look at both the field itself and the related patient, insured, provider, and service-line data. Payers evaluate the claim as a connected record.

Document authorization to release information and assignment/payment directions where appropriate.

The payer does not read Patient and Insured Signatures in isolation. We compare it with the surrounding claim data before deciding the entry is ready.

What this affects downstream

An entry for Patient and Insured Signatures may be the right length and still be the wrong value. The surrounding coverage, provider, and service information has to support it.

Passing an edit is not the same as filing an accurate claim. For Patient and Insured Signatures, correct the underlying record instead of substituting a value that merely looks acceptable.

A practical entry routine

1. Identify the person, organization, date, code, or identifier the field is asking for.
2. Locate the source document: insurance card, eligibility response, clinical note, authorization, provider enrollment record, fee schedule, or payer remittance.
3. Enter the value using the form’s structure and the payer’s required format.
4. Compare it with related fields and service lines for consistency.
5. Save evidence of the source and the final submitted claim.

What to double-check

• Using “signature on file” without valid authorization.
• Assuming Box 13 is always required.
• Confusing the two authorizations.

A prior claim is useful for comparison, but we recheck Patient and Insured Signatures against the insurance card, eligibility response, and payer enrollment record. Coverage, enrollment, authorizations, codes, and addresses can change between visits.

Last check before sending

• Maintain signed authorizations.
• Use payer-approved notation.
• Verify assignment policy.
• Protect authorization records.
• Compare the completed claim with the clinical and billing record.
• Confirm the receiving address or electronic route.
• Keep a secure copy and proof of submission.

Using software without skipping review
