Other emphysema

This code represents forms of emphysema that do not fit into the more specific categories of panlobular, centrilobular, or other specified types. It encompasses less common or atypical presentations of emphysema, characterized by permanent enlargement of airspaces distal to the terminal bronchioles, accompanied by destruction of their walls without obvious fibrosis.

Use this code when documentation clearly identifies emphysema but does not specify a subtype that maps to a more precise ICD-10-CM code (e.g., J43.0-J43.2, J43.9). This code is appropriate for conditions like paraseptal emphysema, bullous emphysema (without mention of other types), or when the physician simply states "other emphysema" or "unspecified emphysema" and no further clarification can be obtained.

• Avoid using this code if a more specific type of emphysema (e.g., panlobular, centrilobular) is documented; query the provider if necessary.
• Distinguish from chronic obstructive pulmonary disease (COPD) with emphysema (J44.9) when emphysema is the primary diagnosis and COPD is not explicitly stated as the overarching condition.
• Consider sequencing with codes for associated conditions, such as tobacco use (F17.-) or alpha-1 antitrypsin deficiency (E88.01), if applicable.
