Other specified chronic obstructive pulmonary disease

This code represents chronic obstructive pulmonary disease (COPD) that does not fit the criteria for emphysema, chronic bronchitis, or asthma with COPD, but is clearly defined as a distinct type of COPD. It encompasses various less common or atypical forms of chronic airflow obstruction not otherwise classified.

Use this code when the physician documentation specifies a form of COPD that is not emphysema (J43.-), chronic bronchitis (J42), or asthma with COPD (J44.9), but is clearly identified as a specific, distinct type of COPD. Examples might include certain rare genetic forms of COPD or other well-defined but less common presentations. Documentation must explicitly state "other specified COPD" or describe a specific type of COPD that falls outside the more common classifications.

• Do not use this code if the documentation simply states "COPD" without further specificity; in such cases, J44.9 (Unspecified COPD) is more appropriate.
• Ensure the medical record clearly differentiates this "other specified" COPD from emphysema, chronic bronchitis, or asthma with COPD.
• Always review the entire medical record for any additional manifestations or exacerbations that may require additional codes (e.g., J44.1 for COPD with acute exacerbation).
