Extenders Are

Extenders are:

A) Alphabetic seventh characters used to complete the description of many codes by conveying additional information
B) Codes located directly behind the main term and used only when the documentation has no additional detail on the condition or disease
C) Codes that are unspecified or are most often used with a condition
D) An "x" placed in the fourth-, fifth-, or sixth-character place when needed to enable the seventh character to remain in the seventh-character position
