ISVALID Function
Use: | Checks a diagnosis (ICD) or procedure(CPT4) code for validity. The IFELSE function can be used to display a message to the user. For diagnoses, the ISVALID function can be used to compare ICD-9 code effective and expiration dates to the encounter date. When a diagnosis search is made for an invalid ICD-9 code, the window opens in ICD Legacy Mapping mode, showing the equivalent ICD-10 codes. If an ICD-9 or CPT code has a delete_ind = Y, the function returns an invalid result. |
