Billing Tips

Although Field 9 is listed as 'Not Required' for standard inpatient and outpatient claims, it is best practice to ensure the patient's address is accurately captured in the provider's internal system. In some instances, secondary payers or specific local coverage determinations may reference this data. Always verify if a specific commercial payer requires Box 9 to be populated to avoid administrative rejections.
