Explain the general concept of MS-DRGs.
What will be an ideal response?
MS-DRGs (Medicare severity diagnosis related groups) categorize or "group" diagnoses that are medically related, require similar treatment, and have similar lengths of stay. Each MS-DRG has a preset reimbursement amount that the hospital receives for each case that falls into a specific MS-DRG. Under the prospective payment system, reimbursement is based on the MS-DRG, and the patient's principal diagnosis, secondary diagnosis, procedures, and complications/comorbidity determine the MS-DRG. Other factors that affect MS-DRG assignment include the patient's age and discharge status.
