Which type of conditions would you expect to find under the category of "residual code" in ICD-10-CM?

Residual codes in ICD-10-CM are specifically utilized to indicate conditions that remain after the acute phase of an illness or injury has resolved. These codes are used for situations where the effects of a prior condition continue to persist, even though the initial issue may have been treated or is no longer present.

Choosing rare or non-specific conditions aligns with the definition of residual codes because they often capture lingering effects that are not easily categorized under other specific codes. For instance, after a person has recovered from a specific disease, there might be long-lasting effects that are not fully fleshed out with other, more common codes.

Other conditions such as common infectious diseases, chronic cardiovascular diseases, or acute respiratory diseases typically deal with current health issues rather than the long-term consequences of previously resolved problems. These conditions don't fit the criteria for residual codes as they either describe ongoing states of health or conditions that require immediate attention rather than the lingering effects of a resolved event. Thus, residual codes are more apt for situations that reflect the aftermath of acute conditions, making rare or non-specific conditions the most appropriate choice in this context.
