Lateral Skull Base & Acoustic Neuroma Co-Surgeon Scrubber
Resection of acoustic neuromas and cerebellopontine angle tumors requires seamless collaboration between neurotology and neurosurgery. Yet commercial payers aggressively target Modifier -62 co-surgery claims with mismatched coding denials, unbundle operating microscope microdissection (+69990), and disallow autologous fat graft harvests. Protect your multi-specialty surgical revenue with automated clinical audit rules.
