Reimbursement for partial hospitalization: a survey and policy implications.

Lack of third-party reimbursement is frequently cited as a cause of underutilization of partial hospitalization. The authors contacted a sample of health maintenance organizations (HMOs) and public and private payers to obtain information about their payment policies. They conclude that in the private sector, reimbursement barriers are diminishing but that clinicians frequently must obtain an extracontractual agreement for coverage. Partial hospitalization is particularly attractive to HMOs and others that pay on a capitated basis and can strictly control utilization. A recent clarification of Medicare guidelines may facilitate reimbursement for hospital-based programs, but there remain significant disincentives under the Medicare statute for widespread utilization of partial hospitalization.
