OAK Horizons, Inc. Minimize

AHDI has partnered with OAK Horizons, Inc., to offer a number of specialty modules for exam preparation and continuing education. This is an opportunity for the professional healthcare documentation specialist to increase knowledge and skills, improve quality and production, and learn timesaving research techniques. Each module covers anatomy, physiology, pharmacology, laboratory, word building, terminology, procedures, special tests, and diseases as they pertain to the particular specialty. Participants transcribe physician dictations including chart notes, histories and physical exams, discharge summaries, initial office evaluations, consultations and letter formats utilizing transcription guidelines as they pertain to the specialty/body system.

There is continual testing and evaluation throughout the program. Participants transcribe and verify their work through transcription keys provided for each report. Quizzes are autocorrected and can be retaken at the participants' leisure.

Level 1 courses are great resources to prepare yourself for the AHDI Registered Healthcare Documentation Specialist (RHDS) exam. These courses will also benefit a healthcare documentation specialist that has been out of the industry for a year or more and looking to re-enter the field.

Level 2 courses are geared toward advanced level healthcare documentation specialists, Certified Healthcare Documentation Specialist (CHDSs), or Certified Medical Transcriptionists (CMTs) looking to further their education by increasing their knowledge and improving production. Upon successful completion of each level 2 course CMTs and CHDSs will earn continuing education credits.
