Abnormal results of pulmonary function studies
ICD-10 R94.2 is a billable code used to indicate a diagnosis of abnormal results of pulmonary function studies.
Abnormal results of pulmonary function studies (PFS) indicate deviations from normal respiratory function as assessed through various tests, including spirometry, lung volume measurement, and diffusion capacity tests. These studies are essential in diagnosing and managing respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and restrictive lung diseases. Abnormal findings may include reduced forced expiratory volume (FEV1), decreased vital capacity (VC), or impaired diffusion capacity (DLCO). Clinicians interpret these results in conjunction with patient history, physical examination, and other diagnostic tests to determine the underlying cause of respiratory symptoms. Common causes of abnormal PFS results include obstructive airway diseases, interstitial lung diseases, neuromuscular disorders, and obesity hypoventilation syndrome. Accurate coding requires a thorough understanding of the clinical context and the specific abnormalities identified in the PFS.
Detailed documentation of the patient's history, physical examination findings, and specific pulmonary function test results.
Patients presenting with chronic cough, dyspnea, or wheezing requiring evaluation of lung function.
Consideration of comorbid conditions such as heart failure or obesity that may affect pulmonary function.
Acute care documentation must include the reason for the pulmonary function study and immediate clinical findings.
Patients with acute respiratory distress or exacerbation of chronic lung disease.
Rapid assessment and documentation of abnormal findings are crucial for timely management.
Used when performing spirometry to assess lung function.
Document the type of spirometry performed and the results.
Ensure that the spirometry results are clearly linked to the clinical findings.
Common causes include obstructive lung diseases like asthma and COPD, restrictive lung diseases such as pulmonary fibrosis, and neuromuscular disorders affecting respiratory muscles.
