K80.00 Calculus of gallbladder with acute cholecystitis without obstruction

Name of the Condition

• Calculus of gallbladder with acute cholecystitis without obstruction

Summary

This condition involves the presence of gallstones in the gallbladder accompanied by acute inflammation of the gallbladder lining (cholecystitis) without blocking bile flow. Gallstones form from substances in bile, such as cholesterol or bilirubin, and acute cholecystitis occurs when the gallbladder becomes inflamed, often due to irritation from the stones. Symptoms may include pain, fever, or nausea, and diagnosis typically relies on imaging and clinical evaluation.

Causes

Gallstones form due to imbalances in bile composition, including excess cholesterol, bilirubin, or insufficient bile salts. Acute cholecystitis develops when gallstones irritate the gallbladder wall or obstruct the cystic duct, leading to inflammation. Bacterial infection may also contribute to the inflammatory process.

Risk Factors

• Female gender, especially during reproductive years.
• Obesity or rapid weight loss.
• Family history of gallstones.
• High-fat or low-fiber diet.
• Certain medical conditions, such as diabetes or cirrhosis.
• Age over 40.

Symptoms

• Severe upper right abdominal pain, often sudden and persistent.
• Fever or chills.
• Nausea, vomiting, or loss of appetite.
• Tenderness in the abdomen, particularly when touching the right upper quadrant.
• Bloating or indigestion.

Diagnosis

Diagnosis typically involves abdominal ultrasound to visualize gallstones and assess gallbladder inflammation. Blood tests may evaluate for signs of infection or liver dysfunction. Additional imaging, such as a CT scan or HIDA scan, may be used to confirm cholecystitis or rule out complications like bile duct obstruction.

Treatment Options

• Antibiotics to treat infection and reduce inflammation.
• Pain management with analgesics.
• Surgical removal of the gallbladder (cholecystectomy) for recurrent or severe cases.
• In some cases, endoscopic procedures may be used to address bile duct issues.

Prognosis and Follow-Up

With prompt treatment, most patients recover fully. Follow-up care may include monitoring for recurrent symptoms or complications. Long-term management often involves dietary adjustments and regular check-ups to prevent future gallstone formation.

Complications

• Bile duct obstruction or infection.
• Gallbladder rupture or perforation.
• Pancreatitis (inflammation of the pancreas).
• Sepsis in severe cases.

Lifestyle & Prevention

• Maintain a healthy weight through balanced diet and exercise.
• Avoid rapid weight loss, which can increase gallstone risk.
• Limit high-fat foods and increase fiber intake.
• Stay hydrated and manage underlying conditions like diabetes.

When to Seek Professional Help

Seek immediate medical attention if you experience severe abdominal pain, fever, jaundice, or persistent vomiting. These symptoms may indicate worsening inflammation or complications requiring urgent care.

Tips for Medical Coders

Document the presence of gallstones, acute cholecystitis, and the absence of obstruction clearly in the medical record. Ensure clinical notes support the diagnosis and specify whether imaging or lab results confirm the condition. Code K80.00 is appropriate when gallstones are present with acute cholecystitis but no bile duct obstruction is documented.
