Insurance & Pricing
Many California insurance plans cover medical nutrition therapy when provided by registered dietitians for specific medical conditions like diabetes, metabolic syndrome, or cardiovascular disease. However, coverage for weight loss-focused nutrition counseling varies significantly between plans. Some patients use HSA or FSA funds to cover sessions, while others may need prior authorization from their primary care physician. The insurance checker can help verify your specific coverage before scheduling.
Out-of-pocket costs for nutrition counseling typically range from $100-200 per session, with initial comprehensive assessments potentially costing more due to extended time and detailed analysis. Many patients benefit from package deals for multiple sessions, and some practices offer sliding scale fees based on income. Payment plans may be available for comprehensive programs. Geographic location in San Francisco generally results in higher costs than suburban areas, reflecting both overhead expenses and practitioner expertise. Use the cost calculator to estimate total program costs based on your specific needs and insurance coverage.

Before your first appointment with Sarah Koszyk, gather your insurance card, complete medication list including supplements, and any recent lab results from your primary care doctor. Consider keeping a 3-day food diary beforehand, noting everything you eat and drink along with times and hunger levels. This gives your dietitian valuable insight into current eating patterns and potential areas for improvement. Bring a list of your favorite foods, restaurants you frequent, and any foods you absolutely cannot or will not eat.
Come prepared with specific questions about your weight loss goals, timeline expectations, and any concerns about dietary changes. Ask about strategies for maintaining nutrition during your typical work schedule, commute, and social activities around San Francisco. Be honest about previous diet attempts, what worked, what didn't, and any emotional or stress-related eating patterns. The more information you provide, the more personalized and effective your nutrition plan will be. Expect your first visit to last 60-90 minutes and focus on building a sustainable approach rather than drastic immediate changes.
