What type of bill (TOB) code is represented by 0121?

The type of bill (TOB) code 0121 specifically refers to a hospital inpatient claim that is submitted under Medicare Part B for the complete duration of a patient's stay, which encompasses admission through discharge. This coding signifies that the services rendered during the entire hospital stay are being billed under Medicare Part B, providing a comprehensive view of care provided over the course of the patient’s treatment.
