In simple words: This code describes a sudden, serious stomach or duodenal ulcer that has a hole in it.

This ICD-10-CM code classifies an acute peptic ulcer where the specific location within the digestive system (stomach or duodenum) is unknown, and there is a perforation (hole) in the ulcer.

Example 1: A 60-year-old male patient presents to the emergency room with severe epigastric pain, vomiting blood, and signs of shock.Endoscopy reveals a perforated acute peptic ulcer in the stomach. , A 45-year-old female patient is admitted with sudden onset of intense abdominal pain radiating to the back.Imaging studies confirm a perforated duodenal ulcer requiring immediate surgical intervention., A 72-year-old patient with a history of NSAID use experiences sudden onset of severe abdominal pain.A CT scan reveals a perforated peptic ulcer, and the patient undergoes emergency surgery to repair the perforation and control bleeding.

Complete history and physical examination, including details of symptoms (onset, duration, character, severity, location), vital signs, laboratory results (complete blood count, blood type and crossmatch, electrolyte levels, liver function tests), imaging studies (abdominal X-ray, CT scan), endoscopy report (if performed), operative report (if surgery performed), pathology report (if tissue obtained).

** This code is for acute peptic ulcers only; chronic ulcers require different codes within the K27 range.Detailed documentation is crucial for accurate coding and reimbursement.
