The ICD code J44 is used to code Chronic obstructive pulmonary disease Chronic obstructive pulmonary disease (COPD), also known as chronic obstructive lung disease (COLD) and chronic obstructive airway disease (COAD), among others, is a type of obstructive lung disease characterized by chronically poor airflow. It typically worsens over time.
These supplement the existing recommendations on:
ICD-10 code: J44. 1 Chronic obstructive pulmonary disease with acute exacerbation, unspecified.
The Alphabetic Index leads coding professionals to code J44. 1, COPD with (acute) exacerbation, for exacerbation of COPD.
ICD-Code J44. 9 is a billable ICD-10 code used for healthcare diagnosis reimbursement of Chronic obstructive pulmonary disease. This is sometimes referred to as chronic obstructive lung disease (COLD) or chronic obstructive airway disease (COAD).
ICD-10-CM Code for Unspecified asthma with (acute) exacerbation J45. 901.
Exacerbations of chronic obstructive pulmonary disease (COPD) are episodes of worsening of symptoms, leading to substantial morbidity and mortality. COPD exacerbations are associated with increased airway and systemic inflammation and physiological changes, especially the development of hyperinflation.
Based on the current guidelines, an acute exacerbation is defined as an acute and transient worsening of preexisting symptoms in patients with CRS [7, 8]. However, there is no consensus definition of how to quantify AE due to multifactorial etiologies and inconsistency in endpoint reporting.
9 Chronic obstructive pulmonary disease, unspecified.
9: Fever, unspecified.
Chronic obstructive pulmonary disease with (acute) exacerbation. J44. 1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM J44.
The Alphabetic Index leads coding professionals to code J44. 1, COPD with (acute) exacerbation, for exacerbation of COPD. However, Coding Clinic Fourth Quarter 2017 advises to assign code J43. 9, Emphysema, unspecified, when a patient with emphysema presents with an acute exacerbation of COPD.
ICD-10 code R05 for Cough is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .
0 is coded first, followed by the code for pneumonia, and assigned to DRG 190 COPD with MCC. AECOPD and Pneumonia: When a patient has both pneumonia and acute exacerbation of COPD, it is appropriate to assign both codes J44. 0 [COPD with acute lower respiratory infection] and J44. 1 [COPD with (acute) exacerbation].
Since the term COPD is unspecified and represents any form of unspecified chronic obstructive lung disease, an additional code is not needed when the diagnosis of emphysema is documented in the healthcare record. The emphysema is the specified type of COPD.
If the documentation supports that the patient has a specific type of asthma documented and COPD, both codes could be reported. An example would be documentation in the record is COPD and moderate persistent asthma.
Chronic bronchitis (CB) is closely associated with the frequency and severity of chronic obstructive pulmonary disease (COPD) exacerbation. However, little is known about the impact of CB on COPD exacerbations, severe and non-severe, and on recovery from an exacerbation.
COPD ICD 10 codes and guidelines can be found in chapter 10 of ICD-10-CM manual which is “diseases of the respiratory system”, code range J00 – J99
COPD ICD 10 Code list and guidelines 1 As COPD is a group of diseases it is important to see the coding guidelines properly before deciding which code to be assigned. 2 Look for the notes – Excludes 1, excludes 2, includes, code also, use additional. 3 Excludes 1 note has codes from category J43, J41, J42, J47 and J68.0 4 Asthma of specified type (Eg: mild intermittent asthma) should be coded separately along with COPD. 5 Disease – Airway – Obstructive = Leads to COPD
Groups of lung diseases contribute to COPD, most commonly seen combinations are Emphysema and chronic bronchitis. Cigarette smoking is one of the major risk factor in increasing the number of COPD patients in the world.
Diagnosis of COPD can be done by doing pulmonary function test (PFT), chest X-ray, CT lung or arterial blood gas analysis.
Note: asthma unspecified J45.909 can not be coded with COPD. Asthma can be coded only if it is specified to which type.
Can not code J43.9 (emphysema) as it has excludes 1 note for “emphysema with chronic (obstructive) bronchitis (J44.-)
As COPD is a group of diseases it is important to see the coding guidelines properly before deciding which code to be assigned.
The Alphabetic Index leads coding professionals to code J44.1, Chronic obstructive pulmonary disease with (acute) exacerbation, for exacerbation of COPD. However, Coding Clinic Fourth Quarter 2017 advises to assign code J43.9, Emphysema, unspecified, when a patient with emphysema presents with an acute exacerbation of chronic obstructive pulmonary disease (COPD). The Excludes1 note found at category J44, Other chronic obstructive pulmonary disease, prohibits the reporting of code J44.1 with code J43.9. If only code J43.9 is assigned, the acuity is not captured. What is the appropriate code assignment for an exacerbation of COPD with emphysema?
