Acute appendicitis.
Modifiers may be necessary to indicate the type of procedure performed (e.g., laparoscopic vs. open), the location of service, or the involvement of multiple physicians.
Medical necessity for treatment of acute appendicitis is established by the presence of clinical symptoms and diagnostic findings consistent with the diagnosis.Untreated appendicitis can lead to serious complications such as perforation, abscess formation, peritonitis, and sepsis.
Diagnosis and management of appendicitis may involve a surgeon,a general practitioner, or an emergency medicine physician. Responsibilities may include physical examination, diagnostic testing (such as blood tests, imaging studies),surgical consultation, appendectomy (surgical removal), post-operative care, and monitoring for complications.
In simple words: Acute appendicitis is a sudden inflammation of the appendix, a small part of your intestines. It happens when the appendix gets blocked, usually by poop, causing infection and swelling.
Acute appendicitis is an inflammation of the vermiform appendix, a small, finger-like pouch attached to the large intestine.The inflammation is typically caused by a blockage, often by fecal matter, leading to infection and swelling.
Example 1: A 25-year-old female presents to the emergency department with acute onset right lower quadrant abdominal pain, nausea, vomiting, and fever. Physical exam reveals rebound tenderness at McBurney's point.Diagnosis of acute appendicitis is confirmed by CT scan. The patient undergoes an appendectomy., A 16-year-old male presents with periumbilical pain that has migrated to the right lower quadrant over 24 hours.He reports anorexia, low-grade fever, and mild nausea.Diagnosis of acute appendicitis is suspected, and a laparoscopic appendectomy is performed., A 60-year-old female with a history of Crohn's disease presents with severe right lower quadrant pain and fever.CT reveals a perforated appendix and localized abscess formation.The patient undergoes surgical drainage of the abscess and a right hemicolectomy.
Complete history and physical examination;results of any laboratory tests (CBC, electrolytes, inflammatory markers); imaging studies (ultrasound, CT scan); operative report (if applicable); pathology report (if applicable); post-operative course.
** Further coding specificity may be required based on the complexity and complications of the appendicitis case.
