1. Laparoscopic appendectomy medical necessity - imaging or clinical criteria
Occasional44970 (laparoscopic appendectomy) indicated for acute appendicitis documented by imaging (CT/ultrasound) or strong clinical presentation. Denied when: imaging shows normal appendix, symptoms don't correlate with appendicitis (atypical presentation without imaging confirmation), or diagnosis of exclusion without adequate workup. Laparoscopic approach may be questioned if converted to open not documented.
Common Causes
- • CT scan shows normal appendix but proceeded with surgery - diagnosis not confirmed
- • Abdominal pain but imaging not performed - presumptive appendicitis without confirmation
- • Atypical presentation (no fever, normal WBC) without imaging - need CT/US confirmation
Resolution Strategy
Document acute appendicitis: 'Patient presented with 24 hours RLQ pain, fever 38.7°C, WBC 16,000 with left shift. CT abdomen/pelvis: dilated appendix 11mm, periappendiceal fat stranding, appendicolith. Diagnosed acute appendicitis. Laparoscopic appendectomy performed. Pathology: acute suppurative appendicitis, no perforation. Clinical and imaging findings diagnostic.' Alternative if imaging negative: 'Atypical presentation with 48-hour RLQ pain. CT showed normal appendix but high clinical suspicion (McBurney's point tenderness, guarding, Rovsing's sign positive). Diagnostic laparoscopy revealed inflamed retrocecal appendix not well-visualized on CT. Appendectomy performed. Pathology confirmed acute appendicitis.' Must document: clinical presentation (pain location, fever, physical exam findings), imaging (CT or ultrasound findings), pathology confirming appendicitis, approach (laparoscopic vs open). If imaging normal, must justify surgery with clinical findings and pathology results. Incidental appendectomy (normal appendix) typically not covered.
