What you'll accomplish

By the end of this guide, you'll have a library of reusable prior authorization letter templates in Claude — one for each of your most common insurance situations (Medicare, Medicaid, common commercial payers). When an auth is due, you fill in the blanks and have a complete clinical letter in under 5 minutes instead of 30–45 minutes.

What you'll need

  • A Claude account — free at claude.ai (the free tier works fine)
  • 30 minutes to build your first 3 templates
  • A list of your 3 most common prior auth scenarios (insurance type + service type)
  • Time needed: 30 minutes setup; 5 minutes per auth afterward
  • Cost: Free (Claude free tier)
