Converting data to the binary and varbinary data types is useful if binary data is the easiest way to move data around. Converting any value of any type to a binary value of large enough size and then back to the type, will always result in the same value if both conversions are taking place on the same version of SQL Server. The binary representation of a value might change from version to version of SQL Server.
Note that while CPT codes have five digits, there are not 99,000-plus codes. CPT is designed for flexibility and revision, and so there is often a lot of âspaceâ between codes. Unlike ICD, each number in the CPT code does not correspond to a particular procedure or technology.
CPT is currently identified by the Centers for Medicare and Medicaid Services (CMS) as Level 1 of the Healthcare Common Procedure Coding System. The Current Procedural Terminology (CPT) was developed by the American Medical Association (AMA).
