ICD 10 Coding Basics 2

Question 1

What are 7th character extensions used for in ICD-10-CM?

Accepted Answer

Providing additional information such as initial encounter, subsequent encounter, or sequela

Answer

The 7th character often indicates the encounter type: A (initial), D (subsequent), or S (sequela), particularly for injury and fracture codes.

Question 2

What does 'laterality' mean in ICD-10-CM coding?

Accepted Answer

Specifying which side of the body (right, left, or bilateral) is affected

Answer

ICD-10-CM includes laterality to identify whether a condition affects the right side, left side, or both sides, adding clinical specificity.

Question 3

What is a combination code in ICD-10-CM?

Accepted Answer

A single code that classifies both the diagnosis and a common symptom, manifestation, or complication together

Answer

Combination codes classify two diagnoses or a diagnosis with a complication in a single code, reducing the need for multiple codes.

Question 4

What does 'unspecified' mean in an ICD-10-CM code?

Accepted Answer

The documentation does not provide enough detail to assign a more specific code

Answer

Unspecified codes are used when clinical documentation lacks the detail needed for a more specific code. They should be avoided when more specific information is available.

Question 5

What is the Excludes1 note in ICD-10-CM?

Accepted Answer

A note indicating two conditions cannot occur together, so the codes should never be reported together

Answer

Excludes1 means 'not coded here.' The excluded condition and the code cannot be used together because the two conditions cannot coexist.
