NCICS study guide
NCICS · Work through your exam, one topic at a time.
The Insurance and Coding Specialist certification, designated NCICS, is one of the credentials offered by the National Center for Competency Testing (NCCT), an independent credentialing organization that has tested healthcare professionals and instructors throughout the United States since 1989. NCCT states that its Insurance and Coding Specialist certification is accredited by NCCA. According to NCCT, Insurance and Coding Specialists provide medical billing and coding services to physician's offices and medical specialty practices for health care providers to be paid for services rendered. The credential therefore targets people who work, or want to work, on the revenue side of a medical practice: translating documented encounters into coded claims, handling payer requirements, and supporting reimbursement. Because NCCT publishes a single certification domain description for this role, candidates should expect the exam to draw on the full billing and coding workflow rather than a narrow slice of it. Preparation is self-directed: NCCT lists exam prep materials, including an Interactive Review System, a Practice Exam, and Practice Exam PLUS, alongside a review system demo. Topics on this exam: Medical Billing and Coding Services. The NCICS study guide has 1 section and about 536 words.
01Medical Billing and Coding Services
The Medical Billing and Coding Services domain tests the revenue-cycle mechanics a coding specialist is expected to run end to end: turning provider documentation into defensible codes, assembling a clean claim, and pushing that claim through edits, adjudication, and appeal. Questions typically pair a coding decision with its billing consequence, so you need both the code-set rule and the downstream effect. CPT describes professional and outpatient procedures and services; ICD-10-CM supplies the diagnosis on every claim and is also the inpatient procedure-adjacent vocabulary for morbidity reporting, while ICD-10-PCS is used for inpatient procedures only - never on a physician office claim. HCPCS Level II carries drugs, biologicals, supplies, DME, and ambulance services (J-, A-, E-codes).
