Specialty exams aptly measure preparedness for “real-world” coding by being operative/patient-note based. In addition to questions regarding the correct
application of ICD-10-CM, CPT®, HCPCS Level II and modifier coding assignments, examinees will also be tested on specialty-specific coding and regulations.
- Must schedule examination four weeks in advance
- Must have current AAPC membership
- While there is no requirement, we strongly recommend that the candidate has at least two years of experience in the specialty. Please be aware that these are difficult,
high-level examinations not meant for individuals with little, limited or no coding experience
Examinees that pass a Specialty certification examination will receive recognition in the Healthcare Business Monthly within three months of their examination date and will receive
a diploma suitable for framing.
