This is Joan’s second coding class in her health information management program. Last semester she learned about ICD-10-CM and ICD-10-PCS (ICD-10-CM/PCS). This semester she is taking an advanced ICD-10-CM/PCS course. Her professor stressed the importance of coding from actual records. Joan remembered her brother had copies of his medical records at home and thought it would be good practice for the class. In the next class, Joan brought her brother’s medical records to the professor to use as an example for the coding students.
What should the professor tell Joan?
