Coders should be assessing their knowledge of anatomy and physiology and preparing for ICD-10-CM/PCSâs more detailed documentation requirements for code capture. The upcoming series of articles will review and discuss the various anatomy and physiology body systems as well as how ICD-10-CM/PCS is impacted by them.

Most cases are mild and can be managed at home.
