Projectile vomiting

This code describes the forceful expulsion of stomach contents, often occurring with significant velocity and distance. It is a distinct and more severe form of emesis, differentiating it from typical vomiting. This symptom can be indicative of various underlying medical conditions, particularly those affecting the gastrointestinal tract or central nervous system.

Assign this code when documentation explicitly states "projectile vomiting" or describes emesis with a forceful, projectile nature. It is commonly seen in infants with pyloric stenosis, but can also occur in adults with increased intracranial pressure, bowel obstruction, or severe gastroenteritis. The physician's clear description of the vomiting's characteristics is essential for accurate coding.

• Do not use this code for general vomiting (R11.10) or nausea with vomiting (R11.2) unless projectile nature is specified.
• Always code the underlying cause of the projectile vomiting first, if known and documented.
• Ensure the medical record clearly distinguishes projectile vomiting from non-projectile emesis.
