Diagnosis Code R94.2

ICD-10: R94.2
Short Description: Abnormal results of pulmonary function studies
Long Description: Abnormal results of pulmonary function studies
This is the 2018 version of the ICD-10-CM diagnosis code R94.2

Valid for Submission
The code R94.2 is valid for submission for HIPAA-covered transactions.

Code Classification
  • Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00–R99)
    • Abnormal findings on diagnostic imaging and in function studies, without diagnosis (R90-R94)
      • Abnormal results of function studies (R94)

Information for Medical Professionals

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.
Diagnostic Related Groups
The diagnosis code R94.2 is grouped in the following Diagnostic Related Group(s) (MS-DRG V34.0)

  • 205 - OTHER RESPIRATORY SYSTEM DIAGNOSES WITH MCC
  • 206 - OTHER RESPIRATORY SYSTEM DIAGNOSES WITHOUT MCC

The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

Lung Diseases

When you breathe, your lungs take in oxygen from the air and deliver it to the bloodstream. The cells in your body need oxygen to work and grow. During a normal day, you breathe nearly 25,000 times. People with lung disease have difficulty breathing. Millions of people in the U.S. have lung disease. If all types of lung disease are lumped together, it is the number three killer in the United States.

The term lung disease refers to many disorders affecting the lungs, such as asthma, COPD, infections like influenza, pneumonia and tuberculosis, lung cancer, and many other breathing problems. Some lung diseases can lead to respiratory failure.
