Use of 12X Type of Bill (TOB) for Billing Colorectal Screening Services
Currently, 12X TOB is not a valid TOB for the billing of colorectal screening
services when provided to hospital inpatients under Part B. Providers are currently billing for these services
using TOB 13X. This instruction requires 12X TOB to be used in place of 13X TOB for the billing of colorectal
screening services when provided to hospital inpatients under Part B or when Part A benefits have been
exhausted. Appropriate TOBs for services other than hospital inpatients remain the same. They are 13X, 14X,
22X, 23X, 83X, and 85X.
