If a patient undergoes a biopsy immediately before the definitive surgery for a
frozen section, how should this be coded with ICD-10-PCS codes?
a. The approach to the definitive surgery
b. Suture method
c. Exploratory surgery
d. Open biopsy and definitive surgery - THE CORRECT ANSWER -
Correct Answer: D
The open biopsy is performed prior to the definitive surgery so that the
pathologist can perform a frozen section of the tissue to determine malignancy.
Approaches, suturing, and closure are not coded separately. Exploratory surgery
is not coded when definitive surgery is performed (Leon- Chisen 2017, 92).
A patient is admitted with hypotension due to dobutamine taken and prescribed
correctly. How should this be coded?
a. I95.1, Orthostatic hypotension
T44.5X5A, Adverse effects of dobutamine
b. I95.2, Hypotension due to drugs
T44.5X5A, Adverse effects of dobutamine
c. I95.89, Other hypotension
T44.995A, Adverse effects of dobutamine
d. I95.81, Postprocedural hypotension
T44.995A, Adverse effects of dobutamine - THE CORRECT ANSWER -
Correct Answer: B
This is an adverse effect of a drug as the dopamine was prescribed correctly and
the patient took it correctly. Hypotension, should be assigned to describe the
condition related to the adverse effect. A "T" code should be assigned to indicate
that it is an adverse effect of the drug (HHS 2017, Section I.C.19.e., 74).
In outpatient surgery, a PTCA is completed with insertion of a drug-eluting stent
in the left circumflex artery and a non-drug-eluting stent inserted into the left
,anterior descending artery of this 56-year-old female. Assign the correct CPT
code(s) for this procedure.
92920 Percutaneous transluminal coronary angioplasty; single major coronary
artery or branch
+92921 Each additional branch of a major coronary artery (List separately in
additional to code for primary procedure.)
92928 Percutaneous transcatheter placement of intracoronary stent(s), with
coronary angioplasty when performed; single major coronary artery or branch
+92929 Each additional branch of a major coronary artery (List separately in
addition to code for primary procedure.)
G0290 Transcatheter placement of a drug eluting intracoronary stent(s),
percutaneous, with or without other therapeutic intervention, any method; single
vessel
G0291 Transcathet - THE CORRECT ANSWER - Correct Answer: B
CPT codes 92920-LC and 92921-LD would be reported for transcatheter stenting
(Smith 2017, 227-228).
A patient is treated for esophageal varices with hemorrhage due to cirrhosis. The
diagnostic codes that would be assigned are:
I85.01 Esophageal varices with bleeding
I85.11 Secondary esophageal varices with bleeding
K74.60 Unspecified cirrhosis of liver
a. I85.01, K74.60
b. I85.10, K74.60
c. K74.60, I85.01
d. K74.60, I85.11 - THE CORRECT ANSWER - Correct Answer: D
The patient has cirrhosis of the liver with resulting bleeding esophageal varices.
Cirrhosis of liver is sequenced first followed by the code for the bleeding
esophageal varices (HHS 2017, Section I.A.13, 11).
An example of breast reconstruction is:
a. Total reconstruction
b. Insertion of drains
c. Removal of lymph nodes
d. Mammography - THE CORRECT ANSWER - Correct Answer: A
Both augmentation of breast for improved appearance and reduction of breast size
are considered types of reconstruction (Leon-Chisen 2017, 276-278).
,Assign the correct CPT code for a 50-year-old female patient admitted to
outpatient surgery department for laparoscopic surgical repair of a recurrent,
incarcerated incisional hernia with mesh insertion.
49561 Repair initial incisional or ventral hernia; incarcerated or strangulated
49565 Repair recurrent incisional or ventral hernia, reducible
49566 Repair recurrent incisional or ventral hernia; incarcerated or strangulated
49657 Laparoscopy, surgical, repair, recurrent incisional hernia (includes mesh
insertion, when performed); incarcerated or strangulated
a. 49561
b. 49565
c. 49566
d. 49657 - THE CORRECT ANSWER - Correct Answer: D
Codes 49650-49659 describe procedures related to laparoscopic hernia repairs.
Note that 49657 was a new code in 2009 to specifically describe laparoscopic
surgical repair of recurrent incisional hernia, incarcerated (including mesh
insertion) (Smith 2017, 129).
When coding "arthrocentesis," the code assignment is determined by:
a. Contrast used
b. Size of the joint
c. Approach
d. Description of the closure - THE CORRECT ANSWER - Correct Answer:
B
The size of the joint is a key determination because arthrocentesis codes are based
on whether the joint is small, intermediate, or major (AMA CPT Professional
Edition 2017, 107).
A patient is admitted to the hospital for pain due to displacement of pacemaker
electrode. The patient also has hypothyroidism due to partial thyroidectomy seven
years ago and a breast cyst. The pacemaker electrode was relocated and Synthroid
was given during hospitalization. The diagnostic codes (excluding External
Cause codes) that should be assigned are:
T82.110A Breakdown (mechanical) of cardiac electrode, initial encounter
T82.110D Breakdown (mechanical) of cardiac electrode, subsequent encounter
T82.120A Displacement of cardiac electrode, initial encounter
T82.120S Displacement of cardiac electrode, sequela
N60.09 Solitary cyst of breast
E89.0 Postsurgical hypothyroidism
, a. T82.110A, E89.0
b. T82.110D, E89.0, N60.09
c. T82.120A, E89.0
d. T82.120S, E89.0, N60.09 - THE CORRECT ANSWER - Correct Answer:
C
Code T82.110A pertains to mechanical complications and would not be used. In
this case, there is pain due to the displacement of the electrode. The breast cyst
(N60.09) would not be coded because it does not meet the criteria of the UHDDS
as a secondary condition; it is an incidental finding (HHS 2017, Section III, 103).
Review the Alphabetic Index under Absence, thyroid, with hypothyroidism,
which directs the coder to code E89.0.
Inpatient procedures are coded with:
a. HCPCS
b. CPT
c. ICD-10-PCS
d. ICD-O - THE CORRECT ANSWER - Correct Answer: C
The UHDDS specifies ICD-10-PCS as the code system for inpatient procedures.
Patient with renal tumors received percutaneous cryotherapy ablation of three
tumors on the right kidney in the same operative episode at Memorial Hospital.
Assign a CPT code for this procedure.
50250 Ablation, open, 1 or more renal mass lesion(s), cryosurgical, including
intraoperative ultrasoundguidance and monitoring, if performed
50590 Lithotripsy, extracorporeal shock wave
50592 Ablation, 1 or more renal tumor(s), percutaneous, unilateral,
radiofrequency
50593 Ablation, renal tumor(s), unilateral, percutaneous, cryotherapy
a. 50250
b. 50590
c. 50592
d. 50593 - THE CORRECT ANSWER - Correct Answer: D
Code 50593, Ablation, renal tumor(s), unilateral, percutaneous, cryotherapy is
used for cryoablation of renal tumors (AMA CPT Professional Edition 2017,
333).
If a patient has an excision of a malignant lesion of the skin, the CPT code is
determined by the body area from which the excision occurs and the:
