I took the Henry Harvin medical coding course, which was very helpful in preparing me for the medical coding certification exams. The course covered all the major topics related to medical coding, including ICD-10, CPT, and HCPCS codes. It also provided plenty of practice questions to help me better understand the material. The instructors were knowledgeable and gave clear explanations of the material. I finished the course in just a few weeks, and I highly recommend it to anyone interested in medical coding.
