ICD-10 J44.9

J44.9 is a billable/specific ICD-10-CM code used for "Chronic obstructive pulmonary disease, unspecified." This code falls under the chapter on diseases of the respiratory system.

This code is utilized when a patient has been diagnosed with chronic obstructive pulmonary disease (COPD), but the specific type of COPD is not detailed. It is used in clinical settings for patients who exhibit symptoms of COPD but where further specification has not been provided or determined. COPD is characterized by the loss of elasticity of the bronchial tree and the air sacs, destruction of the air sac’s wall, thickening of the bronchial wall, and mucus accumulation in the bronchial tree. This results in the disruption of the airflow in the bronchial airways. Signs and symptoms include shortness of breath, wheezing, productive cough, and chest tightness.

J44.9 should be used for billing when the patient's medical record includes a diagnosis of COPD without further details. It allows for general classification in cases where the subtype of COPD isn't specified.

Providers should document symptoms, diagnostic tests, and the disease's impact on the patient's quality of life. Although specific subtypes may not be documented, the presence of COPD should be clear from the medical record.

J44.9 is used to document cases of COPD where specific types are not identified, ensuring patients receive appropriate care, and that billing and insurance processing are conducted accurately.
