Rewind: ICD-10-CM by the Alphabet
I like to review the ICD-10-CM by the alphabet at least once per year as it provides an easy way to memorize ICD-10-CM codes or at least the chapters. Last year, I did this review in table form. This year, I thought that I would do the review using pictures.
Chapter 1 is Infectious and Parasitic Diseases (A-B), and the mnemonic is Advancing Bugs. 
Neoplasms are in Chapter 2 and include the beginning letters of C and D. The mnemonic is Cancer and Death.
Chapter 3 (Diseases of Blood and Blood Forming Organs and Certain Disorders Involving the Immune Mechanism) which includes the last portion of the D codes. The mnemonic is Dracula.

The Chapter 19 codes are “Simply Traumatic” that begin with letter “S and T”. The title of this chapter is Injuries and Poisonings. 
Chapter 20 codes represent the External Cause Codes and begin with letters “V, W, X, and Y”. The mnemonics for this chapter of Vehicle, Whoops, eXposure, and whY.
Chapter 21 (Factors Influencing Health Status) codes begin with letter “Z”. The Z codes have a mnemonic of Zero Problems. 
The newest chapter is Chapter 22 which is titled Codes for Special Purposes. These codes begin with the letter “U” and the mnemonic is “Unusual”…
While the mnemonics do not provide the entire code, it is a mechanism to know the approximate meaning for the ICD-10-CM code. Please enjoy the association.
