On 2027 Colorado plans
Do you need a referral? Plan filings list referral rules only for specialists. Some plans need a doctor's order or prior approval for this care, so check the plan's summary of benefits.
What a visit costs (the plan's filed "Nutritional Counseling" benefit, in network, before any extra savings on silver plans):
- Bronze: $0 a visit on 3 of 56 plans; on the other 53, you pay toward your deductible or a share of the bill.
- Silver: $0 to $85 a visit on 16 of 58 plans; on the other 42, you pay toward your deductible or a share of the bill.
- Gold: $0 to $90 a visit on 14 of 30 plans; on the other 16, you pay toward your deductible or a share of the bill.
In-network care costs less. Out-of-network visits on an HMO or EPO usually aren't covered except in an emergency.
