Disorders of diaphragm

This code encompasses various non-congenital conditions affecting the diaphragm's structure or function, excluding hernias. It covers acquired disorders such as diaphragmatic paralysis, eventration, or other unspecified diaphragmatic dysfunction. These conditions can impair respiratory mechanics and lead to breathing difficulties.

Use this code when documentation specifies an acquired disorder of the diaphragm, such as phrenic nerve palsy leading to diaphragmatic paralysis, or an idiopathic eventration of the diaphragm. It is appropriate for conditions that are not congenital and are not classified as a diaphragmatic hernia. Supporting documentation should clearly indicate the acquired nature and specific type of diaphragmatic impairment.

• Differentiate carefully between acquired diaphragmatic disorders and congenital anomalies or diaphragmatic hernias, as these have specific Excludes1 and Excludes2 notes.
• Ensure the medical record explicitly states the disorder is acquired or non-congenital to avoid miscoding with congenital malformations.
• Review for any underlying causes of diaphragmatic dysfunction, such as neurological conditions, which may require additional coding.
