Percentage of venous leg ulcer visits among patients aged 18 years and older in which adequate compression is provided within the 12-month reporting period. Compression method should be appropriate to documented arterial supply. There are four rates reported for this measure. The four rates will be risk stratified into three buckets which are the following: Rate 1: Normal arterial supply- No restrictions on type of compression Rate 2: Compression bandaging with special considerations (e.g. short stretch bandaging, warnings to the patient to remove bandages if they feel too tight, etc.) Rate 3: Compression bandaging not usually recommended Rate 4: The average of the three risk stratified buckets which will be the performance rate in the XML submitted.
