Furthermore, CMS issued quarterly updates to the lists of covered surgical procedures and ancillary services to set payment indicators and rates for newly introduced Level II HCPCS and Category III CPT Codes pertaining to ASC billing and coding.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><a href=\"https:\/\/www.medicalbillersandcoders.com\/speciality\/ambulatory-surgical-centers-medical-billing-services.html\">ASC (Ambulatory Surgical Center) billing and coding<\/a> utilizes Current Procedural Terminology (CPT) codes to document and bill for procedures performed in the facility accurately. Here are some common CPT codes used in ASC billing and coding:<\/p>\n<ol>\n<li><strong>CPT codes for surgical procedures:<\/strong>\n<ul>\n<li>10000 &#8211; 69999 range: These codes cover a wide range of surgical procedures performed in ASCs, including but not limited to:\n<ul>\n<li>Excision of lesions or tumors<\/li>\n<li>Repair of fractures<\/li>\n<li>Arthroscopy procedures<\/li>\n<li>Endoscopic procedures<\/li>\n<li>Laparoscopic procedures<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li><strong>CPT codes for diagnostic procedures:<\/strong>\n<ul>\n<li>70000 &#8211; 79999 range: These codes are used for diagnostic procedures such as:\n<ul>\n<li>Diagnostic endoscopies<\/li>\n<li>Diagnostic colonoscopies<\/li>\n<li>Diagnostic arthroscopies<\/li>\n<li>Diagnostic laparoscopies<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li><strong>CPT codes for anesthesia services:<\/strong>\n<ul>\n<li>00100 &#8211; 01999 range: These codes cover anesthesia services provided during surgical procedures in the ASC.<\/li>\n<\/ul>\n<\/li>\n<li><strong>CPT codes for ancillary services:<\/strong>\n<ul>\n<li>80000 &#8211; 89999 range: These codes include various ancillary services such as:\n<ul>\n<li>Pathology and laboratory services<\/li>\n<li>Radiology services<\/li>\n<li>Rehabilitation services<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li><strong>CPT codes for supplies and materials:<\/strong>\n<ul>\n<li>99000 &#8211; 99091 range: These codes are used to report supplies and materials used during procedures in the ASC.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p>ASC must use the appropriate CPT codes to accurately reflect the services provided, ensuring proper reimbursement and compliance with coding regulations and guidelines. ASCs may also use modifiers with CPT codes to provide additional information about the procedure or service rendered. Keep reading to learn about ASC billing and coding.<\/p>\n<p style=\"text-align: justify;\">The CMS website provides the complete lists of ASC-covered surgical procedures and ancillary services, the applicable payment indicators, payment rates for each covered procedure, and ancillary service before adjustments for regional wage variations, wage-adjusted payment rates, and wage indices.<\/p>\n<p style=\"text-align: justify;\">To be paid under this provision, a facility must be certified as meeting an ASC&#8217;s requirements and enter into a written agreement with CMS. ASCs must accept Medicare\u2019s payment as payment in full for services with respect to those services defined as ASC services. The physician and anesthesiologist may bill and be paid for the professional component of the service.<\/p>\n<p style=\"text-align: justify;\">Other services, such as lab or non-implantable DME, may be performed when billed using the appropriate certified provider\/supplier UPIN\/NPI. The basics of ambulatory surgery center billing aren\u2019t hard to master, but they differ from physician and facility requirements. ASC billing and coding differ from regular physician or facility billing. Unlike physician medical billing, which requires adherence to a few highly specialized guidelines to get reimbursed, Ambulatory Surgery Centers&#8217;\u00a0billing and coding aren&#8217;t centered on a specific medical specialty.<\/p>\n<h2 style=\"text-align: left;\">The following overview will help you know what\u2019s most important in the ASC Billing and Coding:<\/h2>\n<h3 style=\"text-align: left;\">Medicare Claims Submissions<\/h3>\n<p style=\"text-align: justify;\">ASCs have a separate set of billing rules. While CMS may address some issues, most billing guidelines are best obtained from your local carrier or intermediary. Some carriers\/intermediaries issue very detailed guides (e.g., Trailblazer), while others may provide a list of links to the CMS website (e.g., Empire).<\/p>\n<p style=\"text-align: justify;\">To reiterate, an ASC must not report separate line items, HCPCS Level II codes, or any other charges for procedures, services, drugs, devices, or supplies packaged into the payment allowance for covered surgical procedures. The allowance for the surgical procedure itself includes these other services or items. However, CMS strongly encourages billing for drugs and biologicals eligible for separate payments. ASCs should report supplies with the correct HCPCS Level II code and number of units on the claim form.<\/p>\n<h3 style=\"text-align: left;\">Coding for ASC<\/h3>\n<p style=\"text-align: justify;\">Coding for Ambulatory Surgery Centers is a specialty unto itself. It is a facility service, but Medicare requires ASCs to send their bills to the professional fee (Part B) payers using the facility fee (Part A) claim form. There is a different set of regulations and bundling edits for ASCs. Many ASCs use the same codes as the surgeons, but that can be a revenue \u201ckiss of death\u201d and create compliance exposure for every shareholder or partner in the ASC.<\/p>\n<p style=\"text-align: justify;\">The rules of the game are different for ASCs than for surgeons or hospitals; at times, ASCs must follow the rules for doctors, and at other times, they must adhere to the hospital\u2019s rules. A simple modifier used incorrectly can deliver a \u201cfatal blow\u201d to an otherwise clean claim for thousands of dollars.<\/p>\n<h3 style=\"text-align: left;\">Approved Surgical Procedures<\/h3>\n<p style=\"text-align: justify;\">You cannot perform just any procedure in the ASC setting for Medicare patients. Medicare has an \u201capproved\u201d list of procedures for the ASC that CMS has determined does not pose a significant safety risk and does not expect an overnight stay following the surgical procedure. Medicare publishes this list of covered procedures annually and updates it quarterly or as necessary.<\/p>\n<h4 style=\"text-align: left;\">The list of approved procedures is based on the criteria:<\/h4>\n<ul style=\"text-align: justify;\">\n<li style=\"text-align: left;\">They are NOT emergent or life-threatening (for example, a heart transplant or reattachment of a severed limb).<\/li>\n<li style=\"text-align: left;\">They cannot be performed safely in a physician\u2019s office.<\/li>\n<li style=\"text-align: left;\">They can be electives.<\/li>\n<li style=\"text-align: left;\">They can be urgent.<\/li>\n<li style=\"text-align: left;\">Procedures also do not involve major blood vessels or result in major blood loss and cannot involve prolonged invasion of a body cavity.<\/li>\n<\/ul>\n<h3 style=\"text-align: left;\">Device Intensive Procedures<\/h3>\n<p style=\"text-align: justify;\">A modified payment methodology is used for device-intensive procedures (i.e., procedures done specifically to insert a device, such as a pacemaker). The ASC will get paid for the device but will not submit a separate line item. Instead, the ASC would include the cost of the device in the procedure code and submit one line item.<\/p>\n<p style=\"text-align: justify;\">ASCs cannot base prices on the allowable code from the Medicare Physician Fee Schedule (MPFS). For example, if a device-intensive procedure is performed, and the formula is to bill the Medicare allowable plus 10 percent, you may leave money on the table. If the 10 percent increase does not cover the cost of the device, the money will not be recouped. It is important to know the cost to the ASC and add the cost of the device into the allowable.<\/p>\n<h3 style=\"text-align: left;\">Modifiers in the ASC<\/h3>\n<p style=\"text-align: justify;\">Some modifiers used in the ASC are the same as those used by physicians, while others are unique to the ASC facility.\u00a0 ASCs have their modifiers for discontinued procedures. Modifier 73 Discontinued outpatient hospital\/ambulatory surgery center (ASC) procedure before anesthesia is used when preparing for surgery has begun, but anesthesia has not been administered.<\/p>\n<p style=\"text-align: justify;\">The patient has returned to the \u201cprep\u201d area and completed the paperwork. The reason may be that the patient has a low-grade temperature or has eaten within the past four hours. The facility charges for the preparation, etc., but adds the modifier to show that the procedure was not completed.<\/p>\n<p style=\"text-align: justify;\">Modifier 74 Discontinued outpatient hospital\/ambulatory surgery centers (ASC) procedure after the administration of anesthesia is used when the procedure is terminated after anesthesia is administered. Plans can pay from 25 percent to 65 percent of the allowable amount, based on the <a href=\"https:\/\/www.cms.gov\/files\/document\/mln1783722-proper-use-modifiers-59-xe-xp-xs-and-xu.pdf\">modifier<\/a> and documentation of how much of the service was performed.<\/p>\n<p style=\"text-align: justify;\">New modifier PT Colorectal cancer screening test; converted to diagnostic test or other procedure designates that screening colonoscopy was converted to a diagnostic or therapeutic service. For example, a patient presents to the ASC for a screening colonoscopy. He is not high-risk and has no symptoms or complaints. During the colonoscopy, a polyp is found in the sigmoid.<\/p>\n<p style=\"text-align: justify;\">The ASC reports 45380 Colonoscopy, flexible, proximal to splenic flexure; with biopsy, single or multiple instead of 45378 Colonoscopy, flexible, proximal to splenic flexure; diagnostic, with or without the collection of specimen(s) by brushing or washing, with or without colon decompression (separate procedure) or G0121 Colorectal cancer screening; colonoscopy on individual not meeting criteria for high risk. Modifier PT designates the procedure as a screening but results in a diagnostic procedure.\u00a0For Medicare patients, this allows the procedure to be paid as a screening with no co-insurance.<\/p>\n<p style=\"text-align: justify;\">If you feel staffing a skilled revenue cycle team for your ASC is challenging, consider outsourcing. Partnering with a vendor that offers leading technology solutions and services throughout the continuum of care can realize significant efficiencies and bottom-line improvements.<\/p>\n<div class=\"react-scroll-to-bottom--css-wqbpu-1n7m0yu\">\n<div class=\"flex flex-col text-sm pb-9\">\n<div class=\"w-full text-token-text-primary sm:AIPRM__conversation__response\" data-testid=\"conversation-turn-11\">\n<div class=\"px-4 py-2 justify-center text-base md:gap-6 m-auto\">\n<div class=\"flex flex-1 text-base mx-auto gap-3 md:px-5 lg:px-1 xl:px-5 md:max-w-3xl lg:max-w-[40rem] xl:max-w-[48rem] group final-completion\">\n<div class=\"relative flex w-full flex-col agent-turn\">\n<div class=\"flex-col gap-1 md:gap-3\">\n<div class=\"flex flex-grow flex-col max-w-full\">\n<div class=\"min-h-[20px] text-message flex flex-col items-start gap-3 whitespace-pre-wrap break-words [.text-message+&amp;]:mt-5 overflow-x-auto\" data-message-author-role=\"assistant\" data-message-id=\"0eb82276-6ed1-4613-ab49-1243e4ac53d8\">\n<div class=\"markdown prose w-full break-words dark:prose-invert light AIPRM__conversation__response\">\n<p>&#8220;Understanding ASC Billing and Coding&#8221; delves into the intricacies of ASC billing and coding practices.
