How this works (simplified)
- We total timed minutes and compute units with:
floor(total/15) + (total % 15 >= 8 ? 1 : 0). - We then suggest how units might be distributed across codes by descending minutes.
- This is an aid — not billing advice. Different payers may require different methods. Document everything you did.
Education only; not billing, coding, or legal advice. Always follow your current payer rules and clinic policies.
