Aetna billing cheat sheet for dietitians

The codes, units, diagnoses, telehealth rules and preventive routing behind MNT claims to Aetna, with the denials that come back most.

What’s inside

• The codes Aetna's nutritional counseling policy (CPB 0049) lists, from 97802–97804 to the G-codes and S9470, and the minutes-to-units table.
• Which diagnoses CPB 0049 covers, when overweight needs a cardiovascular risk factor, where Z68 and Z71.3 go, and preventive versus medical benefit.
• A clearly marked box on the preventive changes reported for Aetna in September 2026, which we could not confirm in a public Aetna policy.
• Telehealth modifiers and place of service, the 26-visit weight-reduction limit, referrals, and how self-funded and Medicare Advantage plans differ.
• The ten-question benefits check, CO-16, CO-50, CO-96, CO-97 and CO-45 with their fixes, and a checklist to run before you submit.
