A new tool for consultation-liaison funding: modified DRGs to reflect psychiatric comorbidity.

Funding for consultation-liaison (C-L) psychiatry remains an overriding obstacle to its implementation and practice. Several methods have been described to access funds for this subspecialty of psychiatry, but none has been enacted as a policy by third party payers to reimburse adequately for the service. In addition, although the consultation portion of the effort can be reimbursed in part in some cases through fee for services, the liaison portion is dependent on the donation of psychiatry time or the largesse of the host department. The efforts at Stanford to capitalize on the findings that psychiatric and medical comorbidity results in prolonged length of hospital stay and increased health resource utilization suggest that specific DRGs would be important patient groups to screen and charge for psychiatric services. Furthermore, DRGs that are accompanied by a high frequency of psychiatric comorbidity are a "target" for an additional funding aliquot to assess and manage the patient's psychiatric status.
