ICD-10 Code J44.9
Chronic obstructive pulmonary disease, unspecified
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.
Detailed description of J44.9
Use this code 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.
Symptoms commonly associated with J44.9
- Persistent cough, often with mucus
- Shortness of breath, especially during physical activities
- Wheezing
- Chest tightness

- J44.1: Chronic obstructive pulmonary disease with (acute) exacerbation
Appropriate usage of J44.9 for billing
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.
Instructional guidelines for providers coding J44.9
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.
Common pitfalls in coding with J44.9
- Using J44.9 when more detailed information is available that could specify the type of COPD.
- Failure to document supporting diagnostic criteria that justify the use of this unspecified code for billing.
