HIMA 2400 Chapters 5 & 6 2026/2027 | 8 Exam Questions & Answers | CPT Modifiers, Pathology, Laboratory & Radiology Coding

HIMA 2400 Chapters 5 and 6 2026/2027 is a concise 3-page exam study resource containing 8 questions with correct answers focused on essential medical coding concepts for pathology, laboratory services and diagnostic radiology. The material covers CPT modifiers 90, 26 and TC, reference laboratory services, professional and technical components, quantitative and qualitative laboratory testing, X-rays, magnetic resonance angiography (MRA), and CPT pathology and laboratory code conventions. Its direct question-and-answer format makes it useful for rapid review, active recall and preparation for HIMA 2400 quizzes and examinations. A central section focuses on CPT modifiers used for laboratory and diagnostic services. The document presents a scenario involving a physician who collects blood for a T3 test but sends the specimen to an outside laboratory for analysis, identifying modifier 90 for the referenced laboratory situation described in the question. Students also review the distinction between modifier 26, representing the professional component, and modifier TC, representing the technical component. The professional component includes activities such as physician supervision, interpretation and reporting, whereas the technical component encompasses performance-related resources, supplies and equipment. These concepts should be studied alongside the current CPT Professional Edition published by the American Medical Association, which is the authoritative CPT reference for code descriptors, guidelines and modifier use. The diagnostic-services material introduces important radiology and imaging terminology. Students confirm that an X-ray uses ionizing radiation to produce images of structures inside the body and identify magnetic resonance angiography (MRA) as an imaging technique that uses magnetic resonance technology to produce images of blood vessels. Understanding these distinctions is important for health information management students because accurate coding depends on correctly interpreting the diagnostic procedure documented in the medical record. The laboratory section differentiates quantitative and qualitative testing. Quantitative studies provide results expressed as specific numerical amounts or concentrations of an analyte in a specimen, while qualitative screening identifies the presence or absence of a particular analyte, constituent or condition. The resource therefore reinforces both laboratory terminology and the conceptual distinctions students need when interpreting pathology and laboratory documentation. The final question addresses the CPT Pathology and Laboratory section, reinforcing recognition of the numerical range associated with pathology and laboratory procedures. This makes the document particularly useful for students learning how the CPT code set is organized and how laboratory services are classified before progressing to more complex code-selection scenarios. For authoritative study and code verification, students should cross-reference this material with the current American Medical Association CPT code set and official CPT guidelines, since CPT codes, descriptors and coding guidance can change between annual editions. The study document is best used as exam-review material rather than as a substitute for the current official coding manual. Relevant Students: This document is particularly relevant to students enrolled in HIMA 2400 or an equivalent Health Information Management, Medical Coding, CPT Coding, Reimbursement Methodology or Health Information Technology course. It may also benefit medical coding and billing students, health information technology students, coding certification candidates and healthcare administration students reviewing laboratory and radiology coding. The uploaded document does not identify a university or institution, so a university name should not be added to the title unless it can be verified.
