Hi Kari,
I have posted some info for you on both CAC and OCR
Optical Character Recognition, or OCR, is a technology that enables you to convert different types of documents, such as scanned paper documents like medical records, PDF files or images captured by a digital camera into editable and searchable data.
Optical Character Recognition is not the same as Computer Assisted Coding (CAC).
CAC can be defined as the use of computer software to automatically generate a set of medical codes for review and validation based upon clinical documentation.
While CAC utilizes OCR technology—OCR is just one component of the CAC application.
OCR—unlike CAC—does not automatically generate ICD-9-CM codes for validation. It simply highlights some key words for the more common mapping diagnoses for HCC and RxHCC coding.
