What is the difference between outpatient and inpatient coding? Answer: Outpatient coders focus on assigning CPT®, HCPCS Level II, and ICD-10-CM codes. They work in provider offices, outpatient clinics and facility outpatient departments. Outpatient facility coders also work with ambulatory payment classifications (APCs). Inpatient hospital coding focuses on a different subset of skills, where coders work with ICD-10-CM and ICD-10-PCS. These coders also assign Medicare severity-diagnosis related groups (MS-DRGs) for reimbursement. Outpatient coders usually have more interaction throughout the day and must communicate well with providers; inpatient coders tend to have less interaction throughout the day. 3. What is a mid-level provider? Answer: Mid-level providers include physician assistants (PA) and nurse practitioners (NP). Mid-level providers are known also as physician extenders because they extend the work of a physician. 4. Discuss the different parts of Medicare and what each program covers. Answer: l Medicare Part A helps to cover inpatient hospital care, as well as care provided in skilled nursing facilities, hospice care, and home healthcare. l Medicare Part B covers two types of services: 1) Medically necessary provider services that are needed to diagnose or treat a medical condition and that meet accepted standards of medical practice; and 2) preventive services to prevent illness or detect it at an early stage. Medicare Part B is an optional benefit for which the patient pays a premium, an annual deductible and generally has a 20% co-insurance except for preventive services covered under healthcare law. Coders working in provider offices code mainly Medicare Part B claims. l Medicare Part C, also called Medicare Advantage, combines the benefits of Medicare Part A, Part B and sometimes Part D. The plans are managed by private insurers approved by Medicare and may include preferred provider organizations, health maintenance organizations, etc. l Medicare Part D is a prescription drug coverage program available to all Medicare beneficiaries for a fee. Private companies approved by Medicare provide the coverage. CPT® copyright 2018 American Medical Association. All rights reserved. www.aapc.com 1 The Business of Medicine Chapter 1 5. Evaluation and management (E/M) services are often provided in a standard format. One such format is SOAP notes. What does SOAP represent? Answer: S—Subjective — The patient’s statement about his or her health, including symptoms. O— Objective — The provider assesses and documents the patient’s illness using observation, palpation, auscultation, and percussion. Tests and other performed services may be documented here as well. A— Assessment — Evaluation and conclusion made by the provider. This is usually where the diagnosis(es) for the services are found. P— Plan — Course of action. Here, the provider will list the next steps for the patient, whether ordering additional tests, taking over the counter medications, etc. 6. What are five tips for coding operative (OP) reports? Answer: 1. Diagnosis code reporting — Use the post-operative diagnosis for coding unless there are further defined diagnoses or additional diagnoses found in the body or op report findings. If a pathology report is available, use the findings from the pathology report for the diagnosis. 2. Start with the procedures listed — One way to start the research process quickly is by focusing on the procedures listed in the header. Read the note in its entirety to verify the procedures performed. Procedures listed in the header may not be listed correctly and procedures documented within the body of the report may not be listed in the header at all; however, it is a place to start. 3. Look for key words — Key words may include locations and involved anatomical structures, surgical approach, procedure method (debridement, drainage, incision, repair, etc.), procedure type (open, closed, simple, intermediate, etc.), size and number, and the surgical instruments used during the procedure. 4. Highlight unfamiliar words — Research for understanding. 5. Read the body — All reported procedures should be documented within the body of the report. The report’s body may indicate a procedure was abandoned or complicated, possibly indicating the need for a different procedure code or reporting of a modifier. 7. What is medical necessity and what tool can you refer to for the medical necessity of a service? Answer: The term medical necessity relates to whether a procedure or service is considered appropriate in a given circum- stance. Tools to determine medical necessity include national coverage determinations (NCDs), local coverage determina- tions (LCDs), and commercial payer policies. 8. What are common
