Examination of the Accuracy of Coding Hospital-Acquired Pressure Ulcer Stages

Analyses of 2009 and 2010 Medicare claims data show that 54% of claims with a secondary diagnosis code of a pressure ulcer site did not include a stage code, compared to only 10% of claims with a pressure ulcer as a primary diagnosis.

These findings encourage further study of the impact enrollee moves have on their health and health care program costs.

Modeling Per Capita State Health Expenditure Variation: State-Level Characteristics Matter

Authors studied average spending in personal health care per person at the state level for all payers. State-level income, amount of health care, and number of elderly residents explain variation in personal health care spending per person among states over time. The authors tested many models to get improved interpretations of the overall results.
