ICD-10 Code J44.8: Other specified chronic obstructive pulmonary disease
Reviewed by HealthAssure Clinical TeamUpdated 26 May 2026
What is this code?
ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Diseases of the respiratory system (J00-J99).
đź“‹Clinical overview
This ICD-10 code is commonly used when documentation describes obstructive airway disease such as COPD or asthma. The most accurate code depends on whether the record identifies COPD, asthma severity or persistence, acute exacerbation, or status asthmaticus.
When is it used?
- May be used when a clinician documents other specified chronic obstructive pulmonary disease in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code may act more like a grouping or parent code, so a more specific child code may be used in final documentation when available.
What it does not mean
- A code alone does not explain severity, treatment plan, or outcome.
- A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
- This entry may represent a broader category rather than the most specific billable code.
đź©şClinical context
When commonly used
- Primary care, pulmonary, emergency, and inpatient documentation where wheezing, airflow obstruction, COPD management, or asthma control is part of the active encounter.
- Chronic-disease follow-up, utilization review, and discharge workflows where exacerbation status, severity, or persistent-control detail affects the final code choice.
Common workup
- Common related testing on this page includes Spirometry, Arterial blood gas.
- Related procedures or service context already linked on this page include Nebulizer treatment, Pulmonary rehabilitation.
Common management context
- COPD and asthma follow-up often includes symptom review, inhaler or nebulizer medication reconciliation, trigger assessment, pulmonary testing context, and monitoring for flare-ups or exacerbations.
- Documentation usually becomes more specific when the chart identifies acute exacerbation, persistent asthma severity, status asthmaticus, smoking exposure, or chronic bronchitis/emphysema context.
- Specialist context already linked on this page includes Pulmonologist, General Physician.
🔍Key distinctions
Important notes
- COPD and asthma coding is often driven by whether the chart documents stable disease, acute exacerbation, severity, persistence, or status asthmaticus.
- Related respiratory conditions such as pneumonia, acute bronchitis, tobacco exposure, or oxygen dependence may affect the overall clinical picture but can still require separate coding.
