TRICARE generally covers medically necessary prenatal care, including standard diagnostic ultrasounds ordered by your OB provider, as part of maternity benefits. Coverage details can vary by TRICARE plan type (such as Prime or Select) and by whether you're using a military treatment facility or a network provider, so your specific plan documents are always the best source of truth.
Elective, keepsake-style ultrasound sessions — like 4D sessions offered at studios such as Family Tree Oki — are typically categorized differently from diagnostic imaging ordered by a physician. These sessions are usually self-pay, similar to how keepsake ultrasound studios operate stateside, because they aren't ordered as part of your medical diagnostic care.
Before booking any elective service, it's worth a quick call to TRICARE or a check of your plan portal to confirm how your specific plan treats non-diagnostic ultrasound, especially if you're budgeting around other baby-related expenses.
