ICD Code K65.1

ICD code K65.1 is a classification used to identify a peritoneal abscess, which is a collection of pus that forms in the peritoneal cavity, the space within the abdomen that houses various organs. This condition often results from an infection or inflammation in the abdominal area and can cause symptoms such as abdominal pain, fever, and swelling. Proper diagnosis and treatment are crucial to prevent complications.

1. Localized Abdominal Pain: Persistent or severe pain in the abdominal region, particularly if it is localized to a specific area, may indicate the presence of an abscess.

2. Fever and Chills: The patient may experience elevated body temperature and chills, which are common signs of infection and inflammation.

3. Nausea and Vomiting: These symptoms often accompany abdominal infections and can be indicative of an underlying abscess.

4. Abdominal Tenderness: Upon physical examination, the abdomen may be tender to touch, especially in the area where the abscess is located.

5. Swelling or Distension: Visible or palpable swelling in the abdominal area can suggest the accumulation of pus or fluid.

6. Elevated White Blood Cell Count: Laboratory tests may reveal leukocytosis, indicating an immune response to infection.

7. Imaging Findings: Diagnostic imaging, such as an ultrasound or CT scan, may show a fluid-filled cavity or mass in the peritoneal cavity, confirming the presence of an abscess.

8. History of Abdominal Surgery or Infection: A recent history of abdominal surgery, trauma, or infection can increase the likelihood of developing a peritoneal abscess.

9. Bowel Obstruction Symptoms: Symptoms such as constipation, inability to pass gas, or bloating may occur if the abscess exerts pressure on the intestines.

10. General Malaise: The patient may report a general feeling of unwellness or fatigue, which is often associated with systemic infections.

For the ICD code K65.1, which pertains to a peritoneal abscess, the relevant CPT codes that may be applicable for treatment include:

1. 49020 - Drainage of peritoneal abscess or localized peritoneal fluid collection, open.

2. 49021 - Drainage of peritoneal abscess or localized peritoneal fluid collection, percutaneous.

3. 49040 - Drainage of peritoneal abscess or localized peritoneal fluid collection, open, for re-exploration.

4. 49041 - Drainage of peritoneal abscess or localized peritoneal fluid collection, percutaneous, for re-exploration.

5. 49406 - Image-guided fluid collection drainage by catheter (e.g., abscess, hematoma, seroma, lymphocele, cyst); peritoneal or retroperitoneal, percutaneous.

These CPT codes are used to document and bill for the procedures associated with the treatment of a peritoneal abscess as indicated by ICD code K65.1. It's important for healthcare providers to select the appropriate CPT code based on the specific procedure performed.
