About coding laryngeal vertigo
The ICD-10-CM code for laryngeal vertigo is R05.4 (Cough syncope).
Within R05 (cough), R05.4 is specifically for cough syncope. Related codes cover acute cough (R05.1), subacute cough (R05.2), chronic cough (R05.3), other specified cough (R05.8) and unspecified (R05.9).
Code first: syncope and collapse (R55).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
