Billing Guidelines for Well-Child Visits

Well-Child Visits: Services are identified using the CPT Preventive Medicine Services Codes. In some cases, one or two modifiers are required to uniquely identify the service provided. 

Each preventive medicine service code billed will be required to have a referral code with the exception of Family Planning services (99383-99385 with modifier FP, or 99393-99395 with modifier FP). 

Family Planning services do not require a well-child referral code.
