1.1  The contractor shall follow this policy for reimbursing services provided by either network or non-network providers. However, the contractor may use alternative network reimbursement methodologies when approved by the Defense Health Agency (DHA) and the contractor specifically includes them in the network provider agreement.
1.2  This reimbursement policy applies to covered surgical procedures performed in freestanding Ambulatory Surgical Centers (FASCs).
1.3  The contractor shall not exempt ambulatory surgery services provided by FASCs in Maryland from this system and shall reimburse these services using the procedures set forth in this section.
2.1  An FASC is any distinct entity that is classified by the Centers for Medicare and Medicaid Services (CMS) as an ASC under 42 CFR part 416, and has an active participation agreement with both Medicare and TRICARE. FASCs that specifically serve pediatric populations and do not have a Medicare participation agreement, meet TRICARE’s ASC requirements when the facility:
•  Is accredited by the Joint Commission or the Accreditation Association for Ambulatory Health Care, Inc. (AAAHC); and
•  Enters into a participation agreement with TRICARE.
2.2  The contractor shall ensure FASCs do not bill TRICARE beneficiaries for non-covered procedures, unless the beneficiary agreed in advance in writing to pay for the services.
3.1  Effective for service dates on or after October 1, 2023, TRICARE is adopting the Medicare ASC reimbursement system including their ASC fee schedule rules, payment rates, payment indicators, list of covered procedures and ancillary services, and wage indices.
3.2  The payment rates established under this system shall apply only to the facility charges for ambulatory surgery in an FASC. The contractor shall make facility payments to FASCs only for covered services listed on Medicare’s ASC list, except for Current Procedural Terminology (CPT) code 41899 and certain dental procedures. For covered dental procedures (e.g., CPT procedure code 41899), the contractor shall reimburse the ASC facility at the Outpatient Prospective Payment System (OPPS) rate. Refer to TRICARE Policy Manual (TPM), Chapter 8, Section 13.2 for dental care covered in an ASC. Additional services, which are not otherwise packaged into the OPPS payment for a covered dental procedure, and provided on a claim with covered a dental procedures will be subject to the payment methodology as described in this section.
3.3  The facility rate is a standard overhead amount that includes nursing and technician services; use of the facility; drugs, biologicals, and radiology services, for which separate payment is not allowed under OPPS; surgical dressings, splints, casts and equipment directly related to provision of the surgical procedure; materials for anesthesia; Intraocular Lenses (IOLs); and administrative, recordkeeping and housekeeping items and services.
3.4  This facility rate does not include items such as physicians’ fees (or fees of other professional providers authorized to render the services and to bill independently for them); certain laboratory, X-rays or diagnostic procedures for which separate payment is allowed under OPPS; orphan drugs; prosthetic devices (except IOLs); corneal acquisition tissue; brachytherapy services; certain implantable devices with pass-through status under OPPS; ambulance services; leg, arm, and back braces; artificial limbs; and Durable Medical Equipment (DME) for use in the patient’s home.
4.1  Reimbursement
The contractor shall ensure payment to an FASC for covered services and items are the lower of the ASC payment rate or the billed charge. For surgical procedures which are covered under TRICARE, but are not on Medicare’s ASC list of covered surgical procedures, the contractor shall reimburse the rendering provider related professional services bill under the allowable charge method, and shall not make a separate payment for the facility charges. Refer to Chapter 3, Section 1 and Chapter 5 for payment of individual professional services.
4.2  Wage Index
The contractor shall base the reimbursement rates for covered procedure on the national rates established in Medicare’s ASC list, and wage-adjusted for geographic wage variations. To adjust for wage differences, the contractor shall apply the wage adjustment factor to the labor-related portion of the national rate (currently 50%), using the Core-Based Statistical Area (CBSA) value. The contractor shall also apply wage adjustments to covered dental procedures (e.g., CPT procedure code 41899).
4.2.1  The contractor shall not adjust for geographic wage differences for the following: corneal tissue acquisition; drugs and devices with pass-through status under OPPS; brachytherapy sources; IOLs and New Technology IOLs; and separately payable drugs and biologicals.
4.2.2  The contractor shall implement any future changes made by Medicare to the labor-related share, the items and services subject to wage adjustments, and the methodology by which wage adjustments are made.
4.3  Multiple Surgeries and Bilateral Procedures
The contractor shall follow Medicare rules for discounting of multiple surgeries and bilateral procedures performed in freestanding ASCs.
4.4  Payment Indicators
Payment indicators identify whether a procedure code is covered, packaged, or separately payable. The contractor shall follow Medicare guidelines for packaged and bundled items/services. The contractor shall not make a separate payments for such items/services.
4.5  Subsequent Hospital Admission
