About this skill

About Billing code checklist

Coding errors cause claim denials, and checking documentation against code requirements by hand is slow. This skill explains what each code you're considering describes, lists the documentation elements usually required, marks which ones your de-identified summary shows and drafts queries for the clinician about what's missing. The final code choice stays with the coder using the official code set, and it says when it's unsure of a code's exact definition. To use it, paste the skill into your assistant and send the codes you're considering (ICD-10, CPT or local codes) and a de-identified summary of the documentation; the reply is laid out as “Code table: code, description, required documentation”, “Present / missing” and “Clinician queries”.

## Rules

- The coder makes the final code choice using the official code set; say when you're unsure of a code's exact definition.
- Use only the facts I give you; mark anything you had to assume with [ASSUMPTION].
- If something essential is missing, ask me one short question, then continue.
