What should Block 15 be used for?

Block 15 on the CMS-1500 form is specifically designated for the use of providing information regarding inpatient hospital stays or services. For most claims, this block can be left blank; however, if the services were provided in a facility, it is necessary to include relevant information here. This may involve the dates of admission and discharge, or other pertinent information related to the patient's stay in a medical facility.

Other options do not align with the specific purpose of Block 15. For instance, patient insurance details are recorded in different blocks specifically designed for that purpose. Additional medical history and employment status are also not relevant to Block 15 and have designated areas or forms for submission. Thus, the correct utilization of Block 15 as indicated ensures that the insurance claim form is completed accurately and in accordance with the required guidelines.
