As a reminder, there is no limit to the number of days for TRICARE admissions to acute rehabilitation facilities. Admissions and continued lengths of stay are based on medical necessity. Recent changes to TRICARE reimbursement methodology for acute rehabilitation facilities does not impact the length of stay for rehabilitation admissions. Discharges or transitions to other levels of care should be based upon medical necessity and the beneficiary’s overall treatment plan.
See the TRICARE Policy Manual, Chapter 7, Section 18.2, Paragraph 3.1
