Q: Which of the following statements is false regarding ICD-10-PCS?
- Body systems designated as upper or lower contain body parts located above or below the diaphragm respectively.
- It is not required that the coder consult the index first before proceeding to the tables to complete the ICD-10-PCS code.
- It is necessary that the physician document the exact terms used in ICD-10-PCS in order for the coder to select a given value.
- When the word "and" is used in a code description, it means "and/or".
A: It is necessary that the physician document the exact terms used in ICD-10-PCS in order for the coder to select a given value.

Q: If a resection of a joint is performed and then a joint replacement is performed, the coder must:
- code both the resection of the joint and the joint replacement
- code only the resection of the joint
- code only the joint replacement
- query the physician to ask what should be coded
A: code only the joint replacement

Q: If the physician documents "partial resection of the stomach", the coder should:
- code the root operation "Excision"
- code the root operation "Removal"
- query the physician to ask if he means "excision" , "removal", or "resection"
- code the root operation "Resection"
A: code the root operation "Excision"

Q: If a patient has a laparoscopic cholecystectomy converted to an open cholecystectomy, the ICD-10-PCS coding guidelines require that the coder must code:
- open resection of the gallbladder
- percutaneous endoscopic inspection
- both percutaneous endoscopic inspection and open resection of the gallbladder
- open excision of the gallbladder
A: both percutaneous endoscopic inspection and open resection of the gallbladder

Q: If the intended procedure is discontinued before any other root operation is performed, code the root operation ___________________of the body part or anatomical region inspected.
- Inspection
- Excision
- Exploration
A: Inspection

Q: If the patient has a diagnostic procedure performed followed by a more definitive procedure on the same body site during the same operative episode, the coder must code:
- both diagnostic procedure and the more definitive procedure
- the diagnostic procedure
- the more definitive procedure
- the combination code that covers both the diagnostic procedure and the more definitive procedure
A: both diagnostic procedure and the more definitive procedure

Q: When coding non-coronary bypass operations, the fourth character identifies the
_____________________ and the seventh qualifier specifies the _____________________.
- body part bypassed "from" or the origin of the bypass; body part bypassed"to" or the destination of the bypass
- body part bypass "to" or the origin of the bypass; body part bypassed "from" or the destination of the bypass
A: body part bypassed "from" or the origin of the bypass; body part bypassed"to" or the destination of the bypass

Q: When coding coronary bypass operations, the fourth character identifies the _____________and the seventh character qualifier specifies the ______________.
- number of distinct coronary artery sites treated or bypassed to; origin of the bypass or the vessel bypassed from
- number of distinct coronary artery sites treated or bypassed to only
A: number of distinct coronary artery sites treated or bypassed to; origin of the bypass or the vessel bypassed from

Q: If a patient has a left upper lung lobectomy, the coder will code:
- Excision of lung, left
- Resection of upper lung lobe, left
- Resection of lung, left
- Excision of upper lung lobe, left
A: Resection of upper lung lobe, left

Q: If multiple tubular body parts are inspected, the coder must:
- code all body parts inspected
- code the most distal body part inspected
- code the first body part inspected
- query the physician
A: code the most distal body part inspected

Q: The physician documented that the patient had a "Biopsy of a right breast lesion". The root operation to be coded is:
- Biopsy
- Excision
- Diagnostic
- Resection
A: Excision

Q: The fourth character in ICD-10-PCS depicts the body part. Some body parts are further subdivided into more detailed parts. The lung is divided into nine unique body parts; therefore, if one of these unique body parts (such as: right upper lobe of the lung, right middle lobe of the lung right lower lobe of the lung) is removed, the appropriate root operation would be:
- Excision
- Resection
- Partial Excision
- Partial Resection
A: Resection

Q: When an entire lymph node chain is cut out, the appropriate root operation is ___________; but when a lymph node(s) is cut out, the root operation is _____________.
- Resection; Excision
- Excision; Resection
A: Resection; Excision

Q: When coding using the root operation Detachment, the term "ray" is used to describe a particular part of the hand and foot, the 5th ray describes the:
- thumb or big toe
- index finger or second toe
- little finger or little toe
- middle finger or middle toe
A: little finger or little toe

Q: An amputation at the proximal portion of the shaft of the shaft of the humerus, lower arm, femur or lower leg or amputation anywhere along the proximal phalanx of the thumb, finger or toe is called a:
- partial amputation
- low amputation
- mid amputation
- high amputation
A: high amputation

Q: The patient was treated for a wart on the thumb of his left hand. The physician performed cryotherapy of one wart on the thumb on the left hand. The root operation used to describe this procedure is:
- Destruction
- Extirpation
- Excision
- Fragmentation
A: Destruction

Q: If a patient has a cataract extraction that does not involve the insertion of an intraocular lens prosthesis, the root operation used is __________________, but if the patient has the intraocular lens prosthesis inserted at the same operative episode, then the root operation used is _____________________.
- Extraction; Replacement
- Excision: Removal
A: Extraction; Replacement

Q: When a foreign body is removed from a body part, the root operation used is:
- Fragmentation
- Removal
- Extirpation
- Extraction
A: Extirpation

Q: The root operation used to describe an "Extracorporeal Shock Wave Lithotripsy" procedure is:
- Destruction
- Extirpation
- Removal
- Fragmentation
A: Fragmentation

Q: When a drainage procedure is performed for diagnostic purposes, rather than for therapeutic purposes, this is reflected by the _________ character of the ICD-10-PCS code.
- sixth
- seventh
- fifth
A: seventh
