10 multiple-choice questions and 4 flashcards on HCPCS Level II Coding, about 6% of the Medical Coder bank. Every one carries a written rationale.
HCPCS Level II Coding is one of 6 chapters in CoStudy's Medical Coder (CPC/AAPC) bank, and it holds 10 of the bank's 173 multiple-choice questions — roughly 6% of the total. That proportion is not arbitrary: chapters follow the certifying body's published exam outline, and the number of questions in each is set by that domain's published weight, so the share of your practice time this chapter takes matches the share of the real exam it accounts for.
Studying by chapter is worth doing once you have a diagnostic score. A single overall percentage tells you whether you are close; it does not tell you which domain is dragging. Working a weak chapter in isolation, and re-testing it in isolation, is the fastest way to move a score that has stalled — and it is why the mock exams in CoStudy report by domain rather than as one number.
5 questions drawn from this chapter, with the full rationale shown — the controlling principle behind the right answer, and why each wrong option tempts and fails.
-XS modifier means:
Answer: C — Separate structure
X-modifiers (specific subsets of -59): -XE = separate encounter. -XP = separate practitioner. -XS = separate structure (organ). -XU = unusual non-overlapping.
Surgical assistant by a physician assistant is reported with modifier:
Answer: D — -AS
-AS = PA, NP, CNS as assistant at surgery. -80 = MD assistant. -81 = minimum assistant. -82 = when qualified resident surgeon not available.
HCPCS Level II is mostly used for:
Answer: D — Supplies, drugs, services not in CPT
A) ICD. B) Correct — DME, injectables, ambulance. C) CPT. D) Wrong.
Wheelchair, standard, hemi (low seat):
Answer: A — E1083
E1083 = hemi-wheelchair fixed full-length arms. E codes = DME. Specific HCPCS rentals/purchases identify exact device type.
Injection, ondansetron HCl, per 1 mg (HCPCS):
Answer: A — J2405
J2405 = ondansetron HCl injection per 1 mg. Each unit = 1 mg. J2469 = palonosetron. J3490 = unclassified drugs.
