Ambulatory Surgical Center and Birthing Center Services


Ambulatory Surgical Centers (ASC) and Birthing Centers (BC) must be licensed by the Oregon Health Division. ASC and BC services are items and services furnished by an ASC or BC in connection with a covered surgical procedure as specified in the Medical-Surgical Services rule or in the Dental Services rule. Reimbursement is made at all-inclusive global rates based on the surgical procedure codes billed.


If the client has Medicare in addition to Medicaid and Medicare covers a surgery, but not in an ASC setting, then the surgery may not be performed in an ASC.


Global rates include:


Nursing services, services of technical personnel, and other related services;


Any support services provided by personnel employed by the ASC or BC facility;


The client’s use of the ASC’s or BC’s facilities including the operating room and recovery room;


Drugs, biologicals, surgical dressings, supplies, splints, casts, appliances, and equipment related to the provision of the surgical procedure(s);


Diagnostic or therapeutic items and services related to the surgical procedure;


Administrative, record-keeping, and housekeeping items and services;


Blood, blood plasma, platelets;


Materials for anesthesia;


Items not separately identified in section (4) of this rule.


Items and services not included in ASC or BC Global Rate:


Practitioner services such as those performed by physicians, licensed physician assistants, nurse practitioners, certified registered nurse anesthetists, dentists, podiatrists and Licensed Direct Entry Midwives (for birthing centers only);


The sale, lease, or rental of durable medical equipment to ASC or BC clients for use in their homes;


Prosthetic and orthotic devices;


Ambulance services;


Leg, arm, back and neck brace, or other orthopedic appliances;


Artificial legs, arms, and eyes;


Services furnished by a certified independent laboratory.


ASCs and BCs will not be reimbursed for services that are normally provided in an office setting unless the practitioner has justified the medical appropriateness of using an ASC or BC through documentation submitted with the claim. Practitioner’s justification is subject to review by the Division. If payment has been made and the practitioner fails to justify the medical appropriateness for using an ASC or BC facility, the amount paid is subject to recovery by Division.
