Payment Policy for
OWCP pays the lesser of the billed charge (the ASC’s usual and customary fee) or the maximum allowed rate. The base maximum allowable rate for any ASC surgical procedure is 200% of the maximum allowable rate for physician’s professional charge as determined from RVU and conversion factor values associated with each CPT/HCPCS code, and from GPCI values associated with site of service.
State waiver: Ambulatory surgery services provided in a hospital-based ambulatory surgery center in

ASC Billing Information
Modifiers required for ASC.
Modifier –SG must be appended as the first modifier to all surgical procedure codes (CPT/HCPCS) billed by an
Modifiers accepted for ASC.
OWCP will accept all valid CPT and HCPCS modifiers, though only a few will affect payment.
Modifiers affecting payment for ASC
Modifier -50, Bilateral modifier
Modifier -50 identifies cases where a procedure typically performed on one side of the body is performed on both sides of the body during the same operative session. Providers must bill using a single line item for each procedure performed and append modifier -50 to indicate that a procedure was performed bilaterally. The bilateral procedure will be paid at 150% of the allowed amount for that procedure.
Example: Bilateral Procedure, Modifier -50,
Line item CPT Code Maximum Bilateral policy Max allowed
on bill modifier allowable applied amount
1 64721–SG–50 $1,370.76 $2,056.141 $2,056.141
Total allowed amount $2,056.141
1. Bilateral procedure is paid at 150% of maximum allowed amount.
Modifier -51, Multiple surgical procedures modifier,
Modifier -51 identifies when multiple surgeries are performed on the same patient at the same operative session. Providers must bill using separate line items for each procedure performed. Modifier -51 should be applied to the second and subsequent line items. The total payment equals the sum of
100% of the maximum allowable fee for the highest valued procedure according to the fee schedule, plus
50% of the maximum allowable fee for the subsequent procedures with the next highest values according to the fee schedule.
Example: Multiple Procedure, Modifier -51,
Line item CPT code Maximum Multiple procedures Allowed
on bill modifier payment policy applied amount
1 29881–SG $2,113.76 $2,113.761
2 64721–SG–51 $1,370.76 $685.38 $ 685.382
Total allowed amount $2,799.143
1. Highest valued procedure is paid at 100% of maximum allowed amount.
2. When applying the multiple procedure payment policy the secondary procedure billed with a modifier -51 is paid at 50% of the maximum allowed amount for that line item.
3. Represents sum of allowed amounts for line 1 + line 2.
* Pricing examples given in this document are for purposes of illustration only, and reflect RVU and GPCI values that are subject to change.
If the same procedure is performed on multiple levels the provider must bill using the proper number of units to indicate the number of levels.
Modifier -73, Discontinued procedure prior to the administration of anesthesia
Modifier -73 is used when a physician cancels a surgical procedure due to the onset of medical complications subsequent to the patient’s preparation, but prior to the administration of anesthesia. Payment will be at 50% of the maximum allowable fee for the primary procedure only. Multiple and bilateral procedure pricing will not apply.
Modifier -74, Discontinued procedure after administration of anesthesia
Modifier -74 is used when a physician terminates a surgical procedure due to the onset of medical complications after the administration of anesthesia or after the procedure was started. Payment will be at 85% of the maximum allowable fee. Multiple and bilateral procedure pricing may apply to this if appropriate to the circumstances.
Implanted Durable Medical Equipment & Prosthetic Implants
Implants must be billed on a separate line using the appropriate HCPCS code. Many implant items have maximum fees under the OWCP fee schedule and the appropriate HCPCS codes should be used. If no maximum allowable levels are set by the fee schedule, OWCP will pay acquisition cost for implants when the bill is accompanied by a copy of the original invoice clearly showing invoice cost less applicable discounts.
Exception: Intraocular Lenses
Intraocular lenses, including new technology lenses, are bundled into the fee for the associated procedure. Please include the cost of the lens in the charge for the procedure. It is permissible to include a line on the bill with the HCPCS code for an intraocular lens (e.g., V2630, V2631 and V2632) and its associated cost for information purposes only.
Acquisition Costs Policy
Acquisition cost equals the wholesale cost plus shipping, handling and sales tax, net of all discounts. These items must be billed together as one charge. Wholesale invoices for all devices must be retained in the provider’s office files for a minimum of three years. A provider must submit a hard copy of the wholesale invoice when an individual device or supply costs $150.00 or more, or upon request. Payment of a provider’s bill may be delayed if this information is not submitted.
Example: Surgical Procedure with Implant,
Line item CPT code Maximum Acquisition cost Allowed
on bill modifier payment policy applied amount
1 27446–SG $3,651.67 $3,651.671
2 L8699 $9,025.00 $9,025.002
Total allowed amount $12,676.673
1. Highest valued procedure is paid at 100% of maximum allowed amount.
2. Represents the total of wholesale implant cost plus associated shipping, handling and taxes, net of all discounts.
3. Represents sum of allowed amounts for line 1 + line 2.
Spinal Injections
Injection procedures are billed in the same manner as all other surgical procedures with the following considerations:
1. For purpose of multiple procedures discounting, each procedure in a bilateral set is considered to be a single procedure.
2. For injection procedures which require the use of fluoroscopic localization and guidance, ASCs may no longer bill separately for the technical component of the radiological CPT code (e.g., 77003 –TC). Payment for these codes is bundled into payment for the primary procedure.
