Coding Specialists and their supervisors require an expert understanding of the OASIS, Coding Guidelines, and Conventions for both OASIS and coding completion accuracy. The goal is an accurate and complete assessment, a well-constructed patient-centered care plan, and achieved clinical outcomes. Coding must be properly sequenced, reflective of the plan, and completed to the highest level of specificity. To consistently achieve this goal, the coding specialist must be knowledgeable in more than just coding.
Home Health Coding relies on an understanding of complex processes. CMS, through the Balanced Budget Act of 1997, created the 60 day predetermined episodic payment process known as the Prospective Payment System. Major revisions were made to the system in 2008 and again in 2010.
In order to derive the episodic payment amount for each patient, characteristics were predetermined using answers from the OASIS data set.
