The Impact of ICD-10 on MS-DRGs

2009 is the first year that hospitals will experience the full impact of the Medicare Severity Diagnosis Related Groups (MS-DRGs). Many question how the proposed implementation of the International Classification of Diseases Tenth Revision (ICD-10) will change the way inpatient cases are grouped for reimbursement. Further, observers now ask, will implementation of ICD-10 code sets change MS-DRG assignment yet again? Reimbursement crosswalks allow users to easily identify ICD-9 and corresponding ICD-10 codes and MS-DRGs. For a more complete description of the impact of ICD-10 on MS-DRGs, click here. MS-DRG ICD-9 to ICD-10 Conversion Conventions If an ICD-10 code combines the descriptions of two separate ICD-9 codes, then the ICD-10 code replaces the more commonly used ICD-9 code. Several general ICD-9 codes in a ‘cluster’ may be replaced with a single highly specific ICD-10 code. New diagnosis codes could lead to different MS-DRGs and change reimbursement for inpatient stays. As a result, hospitals may forego utilization of your product for another. The Aequitas Group can help you to understand the ICD-9-CM conversion and prepare for ICD-10—preventing significant revenue loss that can result from this change.
