HCPCS S9470: nutritional counseling, dietitian visit

By Javier Alvarez · Updated September 29, 2026 · 3 min read

Most dietitians meet S9470 the same way: a Medicaid manual or a commercial fee schedule lists it where you expected 97802, or a remit comes back saying the plan wanted a different code. It's a real code with a narrow job. Once you know which payers use it, it stops being a mystery.

What S codes are

HCPCS Level II is the national code set that sits next to CPT. Its S codes (S0000–S9999) are temporary national codes created for non-Medicare payers. Private insurers and some Medicaid programs use them for services that have no national code, or that they want to pay differently from the CPT code.

Two consequences follow:

• Medicare doesn't use them. In the October 2026 Medicare Physician Fee Schedule file, S9470 and S9452 both carry status I: not valid for Medicare purposes (CMS PFS files).
• Each payer decides whether and how to pay them. Whether a plan accepts S9470, what it pays and how it counts units live in that plan's policy or fee schedule, not in the code set.

S9470: descriptor and unit

The descriptor is short: nutritional counseling, dietitian visit. Unlike the MNT CPT codes, it says nothing about minutes, and nothing about initial versus follow-up.

• Unit: plans that use S9470 generally pay one unit per visit, whatever the length. A 30-minute visit and a 60-minute visit bill the same.
• Scope: some programs treat S9470 as a lighter service than MNT. Texas's CSHCN Services Program manual calls it "a less comprehensive service" that "does not include an assessment or reassessment," limited to four visits per rolling year (TMHP, Oct 2020).

That's the practical trade-off. Where a plan pays both, 97802/97803 pay by time and S9470 pays by visit. Which one fits a given visit is the plan's call, not yours.

Which payers ask for it

S9470 shows up in published policies, usually next to the MNT codes rather than instead of them:

Medicaid use varies by state and by managed care plan within a state. For the state-level picture, see Medicaid nutrition counseling.

S9452 and other nutrition S codes

• S9452 – nutrition classes, non-physician provider, per session. Some plans use it for classes where you might otherwise bill group MNT (97804).
• S9449 – weight management classes, non-physician provider, per session.

Both are S codes with status I for Medicare. If you run classes for commercial or Medicaid members, ask each plan whether it wants 97804 (per 30 minutes, per participant) or an S code (per session).

How to confirm the payer's code

Ask by code on the benefits or provider-services call, and write the answer down:

1. "For a registered dietitian, do you want nutrition visits billed as 97802/97803 or as S9470?"
2. "Is S9470 paid per visit or per unit? Is there a visit limit?"
3. "If I bill 97803 and S9470 on the same day, what happens?"
4. "Is S9470 on my fee schedule?" (If it isn't, it may not be payable to you even if the member's plan lists it.)

Then check the plan's provider manual or fee schedule to confirm. Our insurance verification call script includes these questions. The MNT billing codes hub lists every code a dietitian is likely to meet.
