Which of the following is NOT a requirement for submitting insurance claims?

Submitting insurance claims requires specific information to ensure that claims are processed accurately and efficiently. The requirement for the patient's employment status is not necessary for the submission of insurance claims, making it the correct answer in this context.

In contrast, each of the other options represents critical components of a claim submission. The patient's Social Security Number may be needed to verify their identity or for specific insurance requirements, although some healthcare practices may use alternate identifiers. The provider's National Provider Identifier (NPI) is essential because it uniquely identifies healthcare providers in billing processes. Diagnosis codes are vital since they provide the rationale for the services rendered and support medical necessity during the claim review.

Thus, the omission of the patient's employment status from the requisite information for submitting claims highlights the focus on more critical data that directly pertains to the provision and reimbursement of healthcare services.
