In a medical office, types of office visits, diagnosis, services, and procedures are converted into codes, so that services rendered can be charged to insurance companies on a CMS-1500 claim form. ICD-9-CM (will change to ICD-10 by October 1, 2014, or later), CPT, and HCPCS are the three coding systems utilized to convert diagnoses, medical services and procedures, and office visits into codes. For this assignment, you will research the differences between coding systems.

Use your textbook, the lecture, or websites to write at least a one-page paper explaining ICD-9-CM, CPT, and HCPCS coding. Your paper must also:

1. Explain ICD-9-CM’s volumes I, II, and III
2. List the six sections and three parts found in the CPT manual. Then discuss the purpose of the Evaluation and Management section
3. Describe V and E Codes in ICD-9-CM
4. Summarize Level I and II of HCPCS

Then click on the following web links to code the following five diagnoses and procedures:
