Aetna considers entry into a medically supervised outpatient pulmonary rehabilitation program medically necessary when all of the following criteria are met: Member has chronic pulmonary disease (including alpha-1 antitrypsin deficiency, asbestosis, asthma, emphysema, chronic airflow obstruction, chronic bron...
Emphysema is defined pathologically as an abnormal, permanent enlargement of the air spaces distal to the terminal bronchioles, accompanied by destruction of their walls and without obvious fibrosis. The 2022 International Classification of Diseases (ICD)-10 diagnosis code for COPD, unspecified is J44.9...
criteria can be used to classify V/Q scans as representing (1) a high probability of pulmonary emboli (PPV greater than 85%), (2) a very low probability (PPV less than 10%), or (3) a normal scan. All V/Q scans not falling into these categories are classified as nondiagnostic, ...
First, due to the unique nature of day surgery, the selection criteria for VATS patients are indeed more stringent, which leads to the patients being relatively young; the applicability of our findings is limited to the context of this study, VATS day surgery, and may not be generalizable to...
Prevalence and severity of COPD were estimated following the Global Initiative for COPD (GOLD) criteria. Variables such as sex, age, current smoking status, smoking intensity (pack years) and type of infection diagnosis were assessed for possible associations with COPD. Results The prevalence of ...
COPD development was determined when all the following criteria were met: (1) age above 40 years; (2) ICD-10 diagnostic code of COPD or emphysema (J43.0x–J44.x, except J43.0, as the primary or secondary diagnosis [within the fourth position]); (3) the use of COPD medications, ...
In the largest multi-ancestry genome-wide association meta-analysis of lung function to date, comprising 588,452 participants, we identified 1,020 independent association signals implicating 559 genes supported by ≥2 criteria from a systematic variant-to-gene mapping framework. These genes were ...
Ninth Revision and International Classification of Diseases, Tenth Revision (ICD-9; ICD-10) codes were used to classify COPD-related events (COPD: ICD-9, 496 and ICD-10, J44; chronic bronchitis: ICD-9, 490-491 and ICD-10 J40-J42; and emphysema: ICD-9, 492 and ICD-10, J43), fol...
[ICD-9-CM] codes 491.21, 491.22, 493.22), emphysema (ICD-9-CM, 492.8), or if they had a principal diagnosis of respiratory failure (ICD-9-CM codes 518.81, 518.82, 518.84) combined with a secondary diagnosis of COPD with acute exacerbation or emphysema,16 and were treated with systemic ...
This study has several limitations. First, we defined IPF using the ICD-10 code assigned by healthcare providers; this may have reduced the diagnostic accuracy owing to inconsistencies with the diagnostic criteria defined by the International Consensus Statement of the American Thoracic Society and Eur...
