Kaiser Permanente nutrition counseling

The short answer

Kaiser Permanente works differently from Aetna, Cigna or a Blue plan. KP is an integrated system: the health plan, the medical groups and many of the clinicians (dietitians included) are part of the same organization. So the usual path for a KP member who needs nutrition counseling is a referral from their KP physician to KP's own nutrition services.

For a dietitian outside KP, that has two consequences:

1. KP pays outside providers only with an approved referral. Kaiser's provider manuals make prior authorization a condition of payment for non-emergency outpatient services.
2. KP doesn't publish an MNT policy with codes, diagnoses or visit limits for outside providers, the way Aetna or UnitedHealthcare do. What it publishes is how referrals and authorizations work, plus some region-specific limits.

How outside referrals work

Northern California. The 2026 Northern California HMO Provider Manual says a request to refer a member to a non-plan provider ("Outside Referrals") is subject to prior authorization, reviewed to determine whether the service is available within KP. It also says prior authorization is "required as a condition of payment for any inpatient and outpatient services (excluding emergency services)." When KP approves a referral, the provider receives a written Authorization for Medical Care that states the referring physician, the scope of services, and the number of visits or duration of treatment.

Washington. The KP Washington Provider Manual 2026 (June 15, 2026) lists authorization limits by service. For nutritional counseling, the limit is 6 visits per 12 months (diabetic education is listed separately, at 999 per 12 months). Authorization requests should arrive before or within 14 calendar days of the requested start date; later requests are treated as retroactive. The manual also notes that members with out-of-network benefits through First Choice Health or First Health can see those networks' providers without prior authorization for office visits. On the member side, KP Washington's nutrition page says a referral from the member's personal physician is required to book an appointment.

Colorado. The KP Colorado Affiliated Provider Manual, Section 4 describes in-house Adult Weight Management and Nutritional Services (nutrition information, weight management and medical nutrition therapy through consults and classes) and pediatric equivalents. For affiliated providers, only one visit or service is allowed per referral unless otherwise indicated, and referrals are reviewed against MCG, KP criteria and, for Medicare members, Medicare national and local coverage determinations.

Other regions publish their own manuals. We didn't find nutrition-specific rules in the Southern California or Mid-Atlantic manuals we checked.

What this means for a private-practice dietitian

• No referral, no claim. Without an approved KP authorization, a claim to KP for a member's visit isn't payable under the manuals above. Check for an authorization number before the first visit, and put it on the claim.
• Stay inside the authorization. Bill only the visits and dates it covers. If you need more, request an extension before the authorization runs out.
• Cash or superbill otherwise. If a KP member wants to see you without a KP referral, set clear expectations: they'd pay you directly, and reimbursement depends on whether their specific plan has out-of-network benefits, which the member's Evidence of Coverage spells out. See what is a superbill and cash pay vs insurance.
• Contracted providers follow their KP agreement and the regional manual. Credentialing with KP is by region and by network need; ask the region's provider contracting team.

Codes and documentation

Because KP doesn't publish MNT billing rules for outside providers, use the standard codes unless the authorization says otherwise: 97802 for the initial assessment and 97803 for follow-ups, both in 15-minute units, and 97804 for groups. The authorization's scope controls. The 8-minute rule for dietitians explains the units.

Send your findings and recommendations back to the referring KP physician after each authorized episode. Good referral communication is covered in physician referrals for dietitians, and authorization mechanics in prior authorization for nutrition services.

Kaiser Medicare members

KP Medicare Advantage plans must cover at least what Original Medicare covers, which for dietitians means MNT for diabetes, chronic kidney disease or a kidney transplant, with a physician referral: 3 hours the first year, 2 after. KP's referral and authorization rules apply on top. The Medicare rules are in Medicare nutrition counseling.

How to verify a Kaiser member's benefits

1. Region and plan: KP operates by region (for example Northern California, Southern California, Colorado, Georgia, Mid-Atlantic, Washington). Plan type decides whether out-of-network benefits exist.
2. Authorization: is there an approved referral to you, with an authorization number, dates and visit count?
3. Scope: which services and how many visits are authorized?
4. Out-of-network benefits, if there's no authorization and the member wants a superbill.
5. Record the rep's name, date and reference number (verification call script).

Not legal or billing advice. Kaiser Permanente rules vary by region and plan; check the member's plan and your authorization before billing.
