PHYSICIAN CASE EXAMPLES PHYSICIAN REIMBURSEMENT Appropriate physician reimbursement relies on thorough documentation which supports accurate coding. The endovascular repair of abdominal aortic aneurysm can be very complex, requiring many component steps, and sometimes involving two physicians acting as either co-surgeons or a primary and an assistant surgeon. The following cases provide reimbursement estimations for various EVAR scenarios. Consult all professional coding resources available for complete discussion of component coding practice. Confirm practices and requirements with local carriers, and utilize a current CPT Professional edition for complete definitions of codes, terminology, and modifiers. MODIFIERS -50 Bilateral Procedure (RVU x 150%) -51 Multiple Procedures (RVU x 50%) -62 Two Surgeons (RVU x 62.5%) -80 Assistant Surgeon (RVU x 16%) -26 Professional Modifier -51 has been used in this Guide to indicate those procedures that are subject to multiple procedure payment reductions. It is not typically necessary to apply this modifier on the claim for professional services, as the payment reduction will be applied automatically by the payer.

TERMINOLOGY AND ACRONYMS A/B MAC: A/B Medicare Administrative Contractor. A Medicare contractor responsible for administration and adjudication of claims for hospital inpatient, hospital outpatient, physicians and ASC treatment settings. ABN: Advance Beneficiary Notice. A legal, written notice to a Medicare beneficiary from a physician or hospital informing the patient that the health service or item that the physician has prescribed is not or may not be a covered service under Medicare and that the patient will be responsible for payment if denied. Anesthesia Guidelines: The rules for coding and charging are complex. Variable circumstances can include duration, method of anesthesia / sedation, the physician or specialist administering services, and the site of service. Local Medicare policies and the AMA CPT coding book, professional edition, should be consulted for questions regarding the proper coding and billing for anesthesia services. APC: Ambulatory Payment Classification. These are numeric classifications used by Medicare to reimburse services performed in a hospital outpatient setting. An APC will contain multiple HCPCS codes that are similar both clinically and in terms of resources used by the hospital. The APC rate is set prospectively by CMS based on historic claims data. APC Status Indicator: Alpha characters are used to designate the APC payment calculation method. For multiple APCs on a single claim with status indicator T the first APC will be paid at 100% and all others at 50%. For all APCs with Status Indicator S each APC will be paid at 100% without discounting. ASC: Ambulatory Surgery Center. When used by Medicare, this designation describes a legal licensing status establishing a site of service distinct from a physician s office or hospital-based facility. Bundled: Certain supplies / procedures provided by a physician as described by CPT / HCPCS codes may be included ( bundled ) with another service for reimbursement purposes. C-APC: Comprehensive Ambulatory Payment Classification. These APCs provide all-inclusive payments for certain procedures. This policy packages payment for all items and services typically packaged under the OPPS and also packages payment for other items and services that are not typically packaged under the OPPS. The single payment for a comprehensive APC excludes services that cannot be covered by Outpatient Department (OPD) services or cannot by statute be paid under the OPPS. Carrier / Part B: A Medicare contractor responsible for physician and ASC medical policies, adjudication of claims, and other administrative functions. CC: Complications and Comorbidities. Patient conditions utilized as two of several factors in MS-DRG groupers. CCI: Correct Coding Initiative. A listing of CPT codes that are designated as comprehensive or component codes. If comprehensive and component codes are submitted on the same bill, only the comprehensive code will be paid unless a modifier is submitted. Medicare uses these as NCCI (National Correct Coding Initiative) edits. CMS: Centers for Medicare & Medicaid Services. The federal agency that runs the Medicare program. CMS also works with the states to run the Medicaid program. CPT Code: Current Procedural Terminology Code. These 5-digit numeric codes are the property of the American Medical Association and are used to describe physician services. Additionally, Medicare licenses these codes from the AMA and uses them to describe physician, hospital outpatient, ASC services, and other outpatient services. DRG: Diagnosis-Related Group. A numeric classification system used by Medicare and some commercial payers to reimburse for hospital inpatient services. The DRG is assigned by software that considers the ICD-10 procedure and diagnosis codes submitted on a claim. DME: Durable Medical Equipment. Certified supplies, prosthetics, equipment, etc. provided to patients in other than a hospital inpatient setting. DMERC: Durable Medical Equipment Regional Contractor. Medicare contractor that adjudicates claims for DME providers. Facility / Non-Facility: For some physician procedures, the reimbursement is determined by the site of service. If the fee is designated as facility, the procedure is performed in a site of service other than a physician office. If the fee is designated as non-facility, the procedure is performed in a physician office. FI: Fiscal Intermediary / Part A. A Medicare contractor responsible for hospital inpatient and outpatient medical policies, adjudication of claims, and other administrative functions. HCPCS: Healthcare Common Procedure Coding System. The name of a coding system established by Medicare to describe services and supplies. The base (Level I) codes are CPT codes. ICD-10: International Classification of Diseases. Alphanumeric clinical coding system for diagnoses and procedures. The combination of procedure and diagnosis codes determines DRG assignment for inpatient reimbursement. ICD-10 procedure 7 character alphanumeric codes (e.g., 04V03DZ Restriction of Abdominal Aorta with Intraluminal Device, Percutaneous Approach) Abbrev: Px. ICD-10 diagnosis 3 7 alphanumeric codes (e.g., I71.4 Abdominal aortic aneurysm, without rupture) Abbrev: Dx. Inpatient: The status used to describe a patient who has been admitted to the hospital. Usually involves multi-day stay. IPPS: Inpatient Prospective Payment System. Medicare per case (see DRG and MS DRG ) methodology for hospital inpatient services. LCD: Local Coverage Determination. The written policies produced by Medicare contractors applicable to geographic areas. A CMS national policy (see NCD ) supersedes a LCD. MCC: Major Complications and Comorbidities. Patient conditions utilized as two of several factors in MS DRG groupers. MCC are typically significant acute manifestations or advanced stages of chronic conditions that would result in higher resource utilization in the course of treatment. MDC: Major Diagnostic Category. Individual MS-DRGs are grouped into mutually exclusive groups based on principal diagnosis. Each group (MDC) generally corresponds to a single organ system and is further organized into a medical or surgical section. A case is assigned to a surgical section MDC based on operating room procedure performed. MS-DRG: Medicare Severity Diagnosis-Related Group. A numeric classification system used by Medicare to reimburse for hospital inpatient services. The MS-DRG is assigned by the combination of ICD-10 procedure codes, diagnosis codes, and the presence or absence of MCC / CCs as derived from the medical record documentation. The MS-DRG system was designed to more accurately pay hospitals based on patient severity of illness. Modifier: A 2-digit alphanumeric code that is appended to a CPT code for further specificity. NCD: National Coverage Determination. The written policies from Medicare that have a national jurisdiction. A NCD supersedes a LCD. Observation: Hospital outpatient services to monitor and assess a patient for determination of hospital admission. OPPS: Outpatient Prospective Payment System. Medicare per group (see APC ) methodology for hospital outpatient services. Outpatient: A patient admitted to a hospital to receive treatment but not admitted as an inpatient (see Observation ). Packaged: Certain supplies / procedures provided by a facility as described by CPT / HCPCS codes may be included ( packaged ) with another service for reimbursement purposes. Prospective: A predetermined reimbursement rate, regardless of the cost of that service. Pro / Tech: Professional / Technical. For some diagnostic tests, the physician reimbursement is established in two components. The professional component is for the physician supervision, interpretation, and other personal service. The technical component is for the equipment, supplies, staff, and other costs related to the test. S&I: Supervision and Interpretation. This term is sometimes used to differentiate the imaging service (professional reading / interpretation) from other components of the procedure, such as introduction and placement of catheters. Unadjusted Rate: The prospective reimbursement rate before it is adjusted for local factors such as the wage index, graduate medical education, outlier cases, disproportionate share, and other factors. This is sometimes called the national average rate. All Medicare reimbursement will have local adjustment factors. RESOURCES Suggested Resources: Coding and reimbursement is complex, specific to case documentation and variable by geographic location. Always consult current physician, hospital and ASC resources.
