Cough syncope

This code represents a transient loss of consciousness (syncope) that occurs specifically due to a paroxysm of coughing. It is a reflex syncope where the increased intrathoracic pressure during a severe cough reduces cerebral blood flow, leading to a brief fainting spell. The patient typically recovers quickly without residual neurological deficits.

Assign this code when documentation clearly indicates syncope directly precipitated by coughing. This diagnosis is often made after ruling out other causes of syncope, such as cardiac arrhythmias or neurological disorders. Look for physician notes describing "cough-induced syncope" or "tussive syncope."

• Ensure documentation explicitly links the syncope to coughing; do not assume causation.
• Code any underlying condition causing the cough (e.g., bronchitis, asthma) as a primary diagnosis, with this code as a secondary diagnosis.
• Differentiate from other types of syncope (e.g., vasovagal, cardiac) which have distinct ICD-10-CM codes.
