Documentation

Best-practice checklist

  • Status post tonsilloadenoidectomy
  • Date of tonsilloadenoidectomy
  • Indications for surgery (e.g., OSA, recurrent tonsillitis)
  • Surgical complications, if any
  • Current symptoms related to prior surgery
Mitigation

Best-practice tips

  • 01Document adenoidectomy/tonsillectomy type: total/partial, indication, date.
  • 02Code adenoidectomy/tonsillectomy separately, if applicable.
  • 03For complications, link to original surgery date/documentation.
  • 04Query physician if documentation lacks laterality or surgical approach.
  • 05Check payer guidelines for coding/reimbursement of revisions.
