CodingQuestion 22 of 100

A 'combination code' in ICD-10-CM is a single code that:

a.Combines a CPT and an ICD-10-CM code
b.Merges two unrelated encounters
c.Classifies two diagnoses, or a diagnosis with an associated manifestation or complication, in one code
d.Represents a bundled surgical package

Explanation

A combination code captures either two diagnoses, or a diagnosis together with an associated secondary process or complication, in a single code. When a combination code fully describes the condition, only that code is assigned. Assigning separate codes instead would result in unnecessary and potentially incorrect reporting.
