The 2022 edition of ICD-10-CM Q79.1 became effective on October 1, 2021. This is the American ICD-10-CM version of Q79.1 - other international versions of ICD-10 Q79.1 may differ. A congenital abnormality characterized by the elevation of the diaphragm dome.
Other congenital malformations of diaphragm. Q79.1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2018/2019 edition of ICD-10-CM Q79.1 became effective on October 1, 2018.
Elevated hemidiaphragm occurs when one side of the diaphragm becomes weak from muscular disease or loss of innervation due to phrenic nerve injury. Patients may present with difficulty breathing, but more commonly elevated hemidiaphragm is found on imaging as an incidental finding, and patients are asymptomatic.
Sensory innervation of the diaphragm is from the intercostal nerves 6-11. Elevated Hemidiaphragm is a condition where one portion of the diaphragm is higher than the other. Often elevated hemidiaphragm is asymptomatic and visualized as an incidental finding on radiologic studies like chest X-ray or chest CT (computed tomography).

During inspiration, the diaphragm flattens pulling air into the lungs, where as during expiration, the diaphragm relaxes, allowing air to flow out of the lungs passively. As the diaphragm flattens during inspiration subatmospheric, negative pressure is created within the thoracic cavity that overcomes atmospheric pressure.
As the diaphragm relaxes, the tension on the chest wall muscles decreases, causing the muscles to recoil and passively push the air out during expiration. The diaphragm has three points of origin, creating a C shape that culminates in a stable, dense fibrous center tendon.
The diaphragm is the primary muscle for inspiration along with secondary muscles such as the sternocleidomastoid, external intercostals, and scalene muscles.
When the pressure gradient cannot be maintained, the right atrium will collapse , and the patient may present as though they have cardiac tamponade. Accurate diagnosis, treatment, and management of elevated hemidiaphragm are essential in patients presenting with dyspnea and multi-organ involvement.
However, evidence suggests that the function of the contralateral, healthy hemidiaphragm may be impacted by lower abdominal pressure. In severe cases of unilateral hemidiaphragm paralysis, patients may lose their inspiratory capacity, which can impair the ability of the heart to pump efficiently.
