Mastery of the 2026 CPC examination requires transcending rote memorization to achieve fluid,
intuitive navigation of the CPT®, ICD-10-CM, and HCPCS Level II frameworks. By internalizing
the architectural logic of these code sets, the medical coder forges academic theory into elite,
audit-proof clinical application.

PART II: THE ELITE TEST BANK
Tier 1: Foundational Syntax & Application
Q1: A 68-year-old patient with confirmed Stage 3b chronic kidney disease (CKD) and essential
hypertension presents for a routine metabolic evaluation. The provider’s documentation lists
both conditions in the assessment but does not explicitly state that the hypertension caused the
CKD. Based on the principles of the ICD-10-CM Official Guidelines for Coding and Reporting,
which diagnostic sequencing is the MOST ACCURATE? A) I10, N18.32 B) N18.32, I10 C) I12.9,
N18.32 D) N18.9, I12.0
● The Answer: C (I12.9, N18.32)
● Distractor Analysis:
○ A is incorrect: The use of I10 (Essential (primary) hypertension) fails to recognize
the mandatory assumed causal relationship between hypertension and CKD
explicitly outlined in the guidelines.
○ B is incorrect: This sequence ignores the causal relationship entirely and incorrectly
lists the localized manifestation code prior to the systemic etiology code, violating
standard sequencing protocols.
○ D is incorrect: Code I12.0 is strictly reserved for hypertensive CKD presenting with
Stage 5 or End Stage Renal Disease (ESRD). Furthermore, N18.9 indicates an
unspecified CKD stage, which directly contradicts the highly specific Stage 3b data
documented by the provider.
The Mentor's Analysis: The classification framework fundamentally assumes a causal
relationship between hypertension and chronic kidney disease, creating a mandatory
, combination code. When facing concurrent diagnoses of hypertension and CKD, the immediate
priority is locating the Hypertensive Chronic Kidney Disease category (I12.-) and pairing it with
the specific anatomical stage. By utilizing I12.9, the coder bypasses the common trap of
fragmenting related systemic pathologies into isolated, unrelated symptoms.
Professional/Academic Intuition: Unless explicitly unlinked by the provider, hypertension
and CKD are clinically inseparable in ICD-10-CM.
Q2: Under the 2026 CPT updates for Remote Physiologic Monitoring (RPM), a clinical team
monitors a patient's blood pressure using a digitally connected device. The device successfully
transmits data for exactly 12 days within a 30-day period. Based on the principles of the Digital
Medicine Services Taxonomy, which action is the MOST ACCURATE? A) Report CPT 99454
because 12 days rounds up to the 16-day clinical minimum. B) Report CPT 99445 to capture
the episodic 2-to-15 day monitoring duration. C) Report CPT 99470 to reflect the device supply
and treatment management. D) Do not report any code, as RPM requires a strict 16-day
transmission minimum.
● The Answer: B (Report CPT 99445 to capture the episodic 2-to-15 day monitoring
duration.)
● Distractor Analysis:
○ A is incorrect: Medical coding strictly prohibits rounding up transmission days to
meet statutory minimums; 99454 explicitly requires 16 or more days without
exception.
○ C is incorrect: Code 99470 is a treatment management code requiring 10-19
minutes of clinical staff time, not a code utilized for the physical supply and
transmission of a digital device.
○ D is incorrect: The 2026 update established 99445 specifically to eradicate the
legacy 16-day limitation, allowing for episodic monitoring reimbursement that was
previously unbillable.
The Mentor's Analysis: The evolution of digital medicine necessitates granular tracking of
physiological data without overburdening the patient with unnecessary extended monitoring.
When facing an episodic data transmission window of less than 16 days, the immediate priority
is applying the newly established episodic supply codes. By utilizing 99445, the facility bypasses
the legacy trap of forfeiting revenue for short-term, highly targeted clinical monitoring.
Professional/Academic Intuition: The 16-day RPM threshold is no longer absolute; 2-15
days of transmission now secures baseline episodic reimbursement.
Q3: An established patient initiates an audio-only telephone communication with their primary
care provider to determine if an in-person evaluation is necessary for a new rash. The total
medical discussion lasts exactly 8 minutes, and the provider decides an in-person visit is not
required. Based on the principles of the 2026 Telemedicine CPT framework, which action is the
MOST ACCURATE? A) Report CPT 98016 for a brief communication technology-based service.
B) Report CPT 98004 utilizing the audio-only modifier 93. C) Report an unlisted E/M service
because the encounter was under 10 minutes. D) Append modifier 25 to the standard office visit
code to indicate the triage nature of the call.
● The Answer: A (Report CPT 98016 for a brief communication technology-based service.)
● Distractor Analysis:
○ B is incorrect: Code 98004 is reserved for synchronous audio-video E/M services
for established patients that meet straightforward medical decision-making criteria
and must exceed 10 minutes in duration.
○ C is incorrect: An unlisted code is inappropriate when a highly specific Level I CPT
code (98016) exists for this exact service.
