What is denoted by the term "Manifestation codes" in ICD-10-CM?

Manifestation codes in ICD-10-CM are specifically used to represent conditions that are symptomatic manifestations of an underlying disease or condition. These codes are important because they allow for a more comprehensive representation of a patient's health status.

When a manifestation code is used, it typically indicates that there is an underlying condition that is causing the manifestation, and the manifestation itself will not be appropriately coded as a standalone entity. For instance, if a patient has diabetic neuropathy, the underlying condition (diabetes) and the manifestation (neuropathy) would both need to be coded to accurately reflect the patient's health situation.

In contrast, the other options do not accurately describe manifestation codes. For instance, codes that detail additional complications or codes requiring further specification may not relate directly to the underlying conditions that manifestation codes denote, as they serve different purposes within the coding structure.
