Homecare Aptitude Test: 2009 Coding Changes
Homecare Insider, January 5, 2009
On October 1, 2008, annual updates to the International Classification of Diseases, 9th Clinical Modification (ICD-9-CM), took effect. Some of these changes have an impact on diagnosis coding and payment for homecare providers. Test your knowledge with these true-or-false questions.
1. A V code for personal history generally supports reasonable and necessary service delivery.
2. The patient’s primary reason for homecare is treatment of a Stage IV pressure ulcer on his hip. Report pressure ulcer – hip (707.4) as the principal diagnosis with pressure ulcer Stage IV (707.24) as the first pertinent.
3. Secondary diabetes (249) is a new case-mix diagnosis for patients in the Prospective Payment System (PPS).
4. A new case-mix diagnosis code, coronary atherosclerosis due to lipid rich plaque (414.3) is a manifestation code.
5. The newly released “Attachment D: Selection and Assignment of OASIS Diagnoses” dramatically changes the approach to homecare coding.
