Confinement. That period of time from the day of admission to a hospital or other institutional provider, to the day of discharge, transfer, or separation from the facility, or death. Successive admissions also may qualify as one confinement provided not more than 60 days have elapsed between the successive admissions, except that successive admissions related to a single maternity episode shall be considered one confinement, regardless of the number of days between admissions.
32 CFR § 199.2
General. In an effort to be as specific as possible as to the word and intent of CHAMPUS, the following definitions have been developed. While many of the definitions are general and some assign meaning to relatively common terms within the health insurance environment, others are applicable only to CHAMPUS; however, they all appear in this part solely for the purpose of the Program. Except when otherwise specified, the definitions in this section apply generally throughout this part.
