BASIC STEPS TO C O DING DISEASES 1. Locate main term in Index to Diseases 2. Follow directional terms

? e.g., see, see also, see category 3. Review diagnostic statement to locate essential

modifiers (sub-terms) in Index to Diseases 4. Select and verify code in Tabular List of Diseases

BASIC C O DING TIPS

? Start looking up the codes from the top down

? Looking up codes from the middle of the page will lead you the WRO NG way!

? Use colored tabs to mark the alphabet and the sections

SEVENTH C HARAC TERS

? Some categories require a se ve nth c ha ra c te r to provide further specificity about the condition being coded.

? May be a number or a letter ? Must a lwa ys be in the se ve nth po sitio n

Examples:

S12.000B Displaced fracture, first cervical vertebra, initial encounter for open fracture

T23.391D Third degree burn, multiple sites, right hand, subsequent encounter

PLAC EHO LDER

ICD-10-CM utilizes a Pla c e ho lde r C ha ra c te r ? "X" for codes that requires a 7th character, but may not have 6 preceding characters.

Example:

S54.02xA, Injury of ulnar nerve at forearm level, left arm

V98.3xxD, Accident involving ski lift, subsequent encounter

EPISO DE O F C ARE DEFINITIO NS

7TH C HARAC TER EPISO DE O F C ARE ? A patient may see new and/or different providers

over the course of treatment for an injury
