Summary & Overview
HCPCS S9989: Services Provided Outside the United States
HCPCS Level II code S9989 designates services provided outside of the United States and is used in claims to indicate that a listed service was delivered internationally. Nationally, accurate use of this code affects claims adjudication, network considerations, and cross-border benefit determinations for patients who receive care abroad. It is an adjunct reporting code and does not describe a clinical procedure by itself.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how S9989 is applied in claims submission, the contexts in which it appears, and the implications for billing workflows and payer review. The publication outlines typical use cases, common modifiers associated with international services (provided in separate sections), and where data is unavailable.
This summary provides national context for administrators, coding professionals, and policy stakeholders seeking clarity on handling claims for care delivered outside the United States. The report also highlights benchmarking and policy considerations relevant to payers and billing teams, and lists gaps where input data was not provided.

Clinical Context
A patient traveling internationally requires a medical procedure or professional service provided outside the United States. Typical scenarios include U.S. beneficiaries enrolled in Medicare or commercial plans who receive care while abroad for an acute condition, elective procedure, or specialist consultation not available locally. The clinical workflow begins when the patient presents to a foreign hospital or ambulatory clinic. The treating provider documents the visit, diagnoses, procedures, and any complications. The provider or facility prepares claims for submission to the U.S. payor using HCPCS Level II code S9989 to indicate the service was provided outside of the United States, in addition to the primary service codes (physician CPT codes or hospital revenue codes) for the actual care rendered. Common documentation elements include international location of service, dates of service, translated clinical notes if required, identification of the U.S. payer, beneficiary information, itemized charges for services rendered, and any applicable local procedure codes mapped to U.S. CPT/HCPCS equivalents. Claims may also include applicable modifiers to convey circumstances such as increased procedural service, unusual anesthesia, or bilateral procedures. Typical sites of service are foreign hospitals, foreign ambulatory surgical centers, and foreign outpatient clinics. Typical patient examples: a Medicare beneficiary treated for appendicitis while traveling in Europe and undergoing appendectomy at a foreign hospital; a commercial plan enrollee receiving urgent orthopedic care for an ankle fracture while abroad; a traveler obtaining a specialist consultation and diagnostic imaging overseas that is billed back to the U.S. insurer using S9989 in addition to the procedure codes for the service provided.
