Question 1: A 68-year-old male is admitted to the inpatient unit with a
primary diagnosis of acute ST-elevation myocardial infarction (STEMI)
of the anterior wall. On day three, the patient develops a secondary acute
myocardial infarction of the inferior wall. The physician documents both
the initial anterior STEMI and the subsequent inferior STEMI in the
final discharge summary. According to ICD-10-CM guidelines, how
should the coder sequence the diagnoses? A) Code the inferior STEMI
first, followed by the anterior STEMI. B) Code the anterior STEMI first,
followed by the inferior STEMI. C) Code only the most recent inferior
STEMI as the principal diagnosis. D) Code both myocardial infarctions
with the same ICD-10-CM code. Correct Answer: B Rationale:
According to ICD-10-CM Official Guidelines, when a patient is admitted
with an acute myocardial infarction and develops another acute
myocardial infarction during the encounter, the code for the infarction
that caused the admission should be sequenced first. Therefore, the
anterior STEMI is the principal diagnosis, followed by the inferior
STEMI.
Question 2: An inpatient is admitted with pneumonia. The physician
documents "pneumonia due to Pseudomonas." The patient also has a
documented history of asthma, which is not currently being treated or
exacerbated during this stay. Which ICD-10-CM codes should be
assigned? A) J18.9, J45.909 B) J15.1, J45.909 C) J15.1 D) J18.1, J45.20
Correct Answer: C Rationale: The code J15.1 specifically identifies
pneumonia due to Pseudomonas. According to coding guidelines, a
history of a condition that is not currently affecting the patient's care or
treatment during the encounter should not be coded. Since the asthma
is not exacerbated or treated, it is not coded.
,Question 3: A patient presents to the outpatient clinic for a follow-up
visit regarding type 2 diabetes mellitus. The physician documents that
the diabetes is well-controlled with diet alone. The patient also has a
documented history of a healed fracture of the right femur from three
years ago. The encounter involves a straightforward medical decision-
making (MDM) level. What is the appropriate E/M code and diagnosis
code(s)? A) 99212, E11.65, Z87.81 B) 99213, E11.9 C) 99212, E11.9 D)
99213, E11.65, Z87.81 Correct Answer: C Rationale: For an established
patient, a straightforward MDM corresponds to CPT code 99212. The
diabetes is controlled by diet, so E11.9 (Type 2 diabetes mellitus without
complications) is appropriate. A history of a healed fracture (Z87.81) is
not coded unless it impacts current care, which is not indicated here.
Question 4: A patient undergoes an inpatient procedure where the
surgeon completely removes the entire gallbladder through an open
incision. In ICD-10-PCS, what is the correct root operation and approach
for this procedure? A) Excision, Open B) Resection, Open C) Excision,
Percutaneous Endoscopic D) Resection, Percutaneous Correct Answer: B
Rationale: In ICD-10-PCS, "Resection" is defined as cutting out or off,
without replacement, all of a body part. Since the entire gallbladder
was removed, Resection is the correct root operation. The approach is
"Open" because it was performed through an open incision.
Question 5: An outpatient undergoes a laparoscopic cholecystectomy.
The surgeon also performs a laparoscopic exploration of the common
bile duct, which reveals no abnormalities. How should the exploration be
coded? A) Code the exploration as a separate procedure with modifier
59. B) Code the exploration using an unlisted laparoscopy code. C) Do
not code the exploration separately, as it is integral to the
cholecystectomy. D) Code the exploration with modifier 52 (Reduced
Services). Correct Answer: C Rationale: Laparoscopic exploration is
considered an integral part of a laparoscopic surgical procedure and is
not coded separately unless a separate, distinct procedural service is
performed and documented. Simply looking around does not constitute
a separate procedure.
Question 6: A patient is admitted to the inpatient facility with urosepsis
and acute urinary retention. The physician documents "urosepsis" but
does not specify the causative organism. According to ICD-10-CM
guidelines, how should this be coded? A) Code N39.0 (Urinary tract
infection) and A41.9 (Sepsis). B) Code R65.20 (Severe sepsis without
septic shock) and N39.0. C) Code A41.9 (Sepsis) and N39.0 (Urinary
,tract infection). D) Code N39.0 only, as "urosepsis" is synonymous with
UTI. Correct Answer: C Rationale: The term "urosepsis" is not a specific
diagnosis in ICD-10-CM. The coder must query the physician or code
the underlying infection (N39.0) and the systemic infection (A41.9). The
sepsis code (A41.9) is sequenced first, followed by the localized infection
(N39.0).
Question 7: An outpatient visits a physician for a routine follow-up of
hypertension. During the visit, the physician also evaluates a newly
developed, significantly itchy rash on the patient's left arm, prescribing a
topical steroid. The E/M service is coded at a level 3. How should the
rash evaluation be reported? A) It cannot be coded separately because it
was evaluated during the same encounter. B) It should be reported with
the appropriate E/M code and modifier 25. C) It should be reported with
the appropriate E/M code and modifier 59. D) It should be reported with
modifier 24 (Unrelated E/M Service by Same Physician). Correct
Answer: B Rationale: Modifier 25 is used to report a significant,
separately identifiable evaluation and management service by the same
physician on the same day of the procedure or other service. Here, the
evaluation of the new rash is distinct from the routine hypertension
follow-up, justifying a separate E/M code with modifier 25.
Question 8: An inpatient has type 2 diabetes mellitus with diabetic
chronic kidney disease (CKD) stage 4. The physician also documents
hypertensive chronic kidney disease. How should these conditions be
coded? A) E11.22, I12.9, N18.4 B) E11.22, I10, N18.4 C) E11.21, I12.9,
N18.4 D) E11.22, N18.4 Correct Answer: A Rationale: Type 2 diabetes
with CKD requires the combination code E11.22. Hypertensive CKD
requires code I12.9. Additionally, the specific stage of CKD (N18.4 for
stage 4) must be coded as an additional code. All three codes are
required to fully capture the clinical picture.
Question 9: A patient undergoes an inpatient cardiac catheterization
where a stent is inserted into the left anterior descending (LAD)
coronary artery using a percutaneous approach. What is the correct ICD-
10-PCS root operation? A) Dilation B) Bypass C) Insertion D)
Replacement Correct Answer: C Rationale: In ICD-10-PCS, the insertion
of a coronary stent is coded to the root operation "Insertion" if it is a
drug-eluting stent, or "Dilation" if it is a bare metal stent or if the stent
is not specified. However, current guidelines specify that the insertion
of a drug-eluting stent is coded to Insertion, while a bare-metal stent is
coded to Dilation. Assuming a standard stent placement without
, specification, "Insertion" or "Dilation" may apply, but "Insertion" is
explicitly used for drug-eluting. Let's clarify: if the question implies a
standard stent, "Insertion" is the root operation for putting in a device.
Wait, coronary stents are coded to Dilation of the coronary artery, and
the stent is coded as the device. Let's correct this: The root operation for
placing a coronary stent is Dilation, and the device is Intraluminal
Device. Let me adjust the question to be precise. Correction for Question
9: A patient undergoes an inpatient cardiac catheterization where a
drug-eluting stent is inserted into the LAD coronary artery. What is the
correct ICD-10-PCS root operation and device? A) Dilation,
Intraluminal Device, Drug-Eluting B) Insertion, Intraluminal Device,
Drug-Eluting C) Bypass, Drug-Eluting Stent D) Replacement,
Intraluminal Device Correct Answer: B (Wait, ICD-10-PCS guidelines
state that the insertion of a drug-eluting stent is coded to the root
operation "Insertion" of the coronary artery, device "Intraluminal
Device, Drug-Eluting". Bare metal stents are coded to "Dilation". I will
use the Insertion root operation for the drug-eluting stent). Let's
rewrite Question 9 clearly: Question 9: A patient undergoes an inpatient
procedure where a drug-eluting stent is placed into the left anterior
descending coronary artery via a percutaneous approach. According to
ICD-10-PCS guidelines, what is the correct root operation? A) Dilation
B) Insertion C) Bypass D) Replacement Correct Answer: B Rationale:
According to ICD-10-PCS guidelines, the placement of a drug-eluting
coronary stent is coded to the root operation "Insertion" with the device
"Intraluminal Device, Drug-Eluting". If a bare-metal stent were placed,
the root operation would be "Dilation".
Question 10: An outpatient undergoes closed treatment of a right distal
radius fracture without manipulation. The physician applies a cast. What
is the appropriate CPT code? A) 25600 B) 25605 C) 25620 D) 25607
Correct Answer: A Rationale: CPT code 25600 represents closed
treatment of a distal radial fracture (epiphyseal separation or fracture)
without manipulation. Code 25605 is with manipulation, and 25607 is
with manipulation and percutaneous skeletal fixation.
Question 11: An inpatient is admitted for a pathological fracture of the
femur due to postmenopausal osteoporosis. The physician performs an
open reduction with internal fixation (ORIF). What is the principal
diagnosis? A) The pathological fracture code (M80.051-) B) The
osteoporosis code (M81.0) C) The external cause code for the fall D) The
code for the ORIF procedure Correct Answer: A Rationale: According to
