Can you bill outpatient labs on a 131 type of bill?

Outpatient labs typically cannot be billed using a Type of Bill (TOB) 131, which is designated for outpatient hospital services. Instead, outpatient laboratory services are generally billed using a TOB 750, which is specifically for outpatient hospital services, including lab tests. It's important to follow the appropriate billing guidelines to ensure compliance and proper reimbursement. Always consult the specific payer requirements for any variations.
