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, often characterized by the destruction of alveolar walls and enlargement of airspaces distal to the terminal bronchioles. The condition leads to impaired gas exchange and chronic airflow limitation.

Use this code when the physician's documentation clearly diagnoses emphysema but does not specify a type that aligns with more granular ICD-9-CM codes (e.g., panlobular, centrilobular, or compensatory). This code is appropriate for cases described as "unspecified emphysema" or "emphysema NOS" when no further detail is available or clinically relevant. Documentation should confirm the presence of emphysema without further classification.

• Avoid using this code if a more specific type of emphysema (e.g., panlobular, centrilobular) is documented.
• Ensure documentation supports a diagnosis of emphysema; do not use for other chronic obstructive pulmonary diseases (COPD) unless emphysema is explicitly stated.
• Consider sequencing this code after any underlying cause or associated conditions, if applicable and supported by documentation.
