Correct Answer
A. ExtenderExplanation
In the ICD-10 coding system, a question mark (?) is often used to indicate an unspecified or placeholder character in a code. Extenders, also referred to as "extensions" or "characters beyond the 4th position," add specificity to the code by providing details about laterality, episode of care, or other clinical information. The extender is part of the latter positions (5th, 6th, or 7th) in an ICD-10 code. Its presence helps coders and clinicians include as much information as possible in a medical diagnosis or procedure code. This makes the extender a key feature for refining coding precision.Rate this question:
