TRICARE Coverage for CPT 89086: Costs & Rules

## Quick answer 89086 is a medical procedure code (CPT code) used for the **evaluation of amniotic fluid** to determine fetal lung maturity. TRICARE covers this test when it is medically necessary to assess if a baby’s lungs are developed enough for a safe delivery in high-risk pregnancies or cases of preterm labor.
## In detail Specifically, CPT 89086 refers to the laboratory examination of amniotic fluid to look for "lamellar bodies." Lamellar bodies are small particles produced by the lungs that indicate the presence of surfactant—a substance that keeps the air sacs in the lungs from collapsing.
### Coverage Requirements TRICARE covers this procedure under its maternity and diagnostic laboratory benefits, provided it meets the following criteria: * **Medical Necessity:** It must be ordered by an OB/GYN or Maternal-Fetal Medicine (MFM) specialist. * **Indications:** Usually performed when there is a risk of preterm delivery (before 37 weeks) or if an early induction or C-section is planned for medical reasons. * **FDA Approval:** The specific testing method used by the lab must be FDA-approved or a validated laboratory-developed test (LDT) meeting TRICARE’s quality standards.
### Costs for CPT 89086 (2026 Rates) Because this is a laboratory service, the cost depends on your plan and the setting where the fluid is collected (e.g., an inpatient hospital stay vs. an outpatient clinic).
| Plan Type | Setting | Estimated Cost (2026) | | :--- | :--- | :--- | | **TRICARE Prime** | Inpatient or Outpatient | $0 copay (with referral/authorization) | | **TRICARE Select (Group A)** | Outpatient Lab | $0 copay (Network) / 25% of allowable charge (Non-network) | | **TRICARE Select (Group B)** | Outpatient Lab | $0 copay (Network) / 25% of allowable charge (Non-network) |
*Note: While the lab test itself (89086) often has a $0 copay for many beneficiaries, the **amniocentesis** procedure (the physical collection of the fluid, often CPT 59000) may trigger a separate cost-share depending on your plan and the location of service.*
### Regional Management As of 2026: * **East Region:** Managed by Humana Military. * **West Region:** Managed by TriWest Healthcare Alliance. Regardless of your region, the laboratory must be TRICARE-certified. If you are using a non-network provider, you may be required to pay upfront and file a claim for reimbursement.
## Who this applies to * **Active Duty Service Members (ADSMs):** Fully covered with no out-of-pocket costs; requires a referral from a primary care manager. * **Active Duty Family Members (ADFMs):** Covered under Prime or Select. Prime users pay $0; Select users pay $0 for the lab but may have cost-shares for the office visit or the amniocentesis procedure. * **Retirees and their Families:** Covered; subject to plan-specific cost-shares and enrollment fees. * **High-Risk Pregnancies:** Specifically those facing preeclampsia, premature rupture of membranes (PROM), or gestational diabetes where early delivery is being considered.
Common scenarios
**1. TRICARE Prime (Active Duty Family Member) in the West Region** Sarah is 34 weeks pregnant and showing signs of preeclampsia. Her doctor at a military facility orders an amniotic fluid test (89086) to see if the baby can be delivered safely. Because she is on Prime and at a military hospital, her total out-of-pocket cost for the test and the procedure is **$0**.
**2. TRICARE Select (Retiree Family Member) in the East Region** Jane (Group B) is 36 weeks pregnant. Her civilian network OB/GYN orders CPT 89086. The lab is a network facility. Jane pays **$0** for the lab test (89086), but she may have a network copay for the specialist office visit (approximately **$39** in 2026) associated with the amniocentesis procedure.
## Related terms * **Amniocentesis:** The surgical procedure used to remove a small amount of amniotic fluid for testing. * **Lamellar Body Count (LBC):** The specific measurement performed under code 89086. * **Fetal Lung Maturity (FLM):** The medical status used to determine if a newborn will likely experience respiratory distress. * **Surfactant:** The substance in the lungs that the 89086 test is indirectly measuring. * **T-5 Contract:** The current TRICARE contract (effective 2025) which transitioned the West Region to TriWest Healthcare Alliance.
