The modules are intended to help prepare residents (and fellows) for practice, in response to multiple requests made to the CREOG education committee for an educational resource on basics of coding and billing. Our intent is that these be utilized for facilitated interactive didactic sessions, ideally a clinician who has attended an ACOG coding conference. We have provided worksheets to accompany the modules with suggestions for implementation. We anticipate creativity in utilizing these materials in the way which is most appropriate for an individual program.
