ICD-10-PCS GUIDELINES |UPDATED 2026’27 |
COMPLETE SOLUTION
How many characters are ICD-10-PCS codes composed of? -ACCURATE
ANSWER seven characters.
Each character is an____ that specifies information about the procedure performed.
-ACCURATE ANSWER axis of classification
Where does a character specify the same type of information in that axis of
classification? -ACCURATE ANSWER Within a defined code range. Example:
The fifth axis of classification specifies the approach in sections 0 through 4 and 7
through 9 of the system.
How many possible values can be assigned to each axis of classification in the
seven-character code? -ACCURATE ANSWER 34 possible valuesValues include:
numbers 0 through 9 and the alphabet (except I and O because they are easily
confused with the numbers 1 and 0).
The number of unique values used in an axis of classification ___. -ACCURATE
ANSWER differs as needed. Example: Where the fifth axis of classification
specifies the approach, seven different approach values are currently used to
specify the approach.
The __ for an axis of classification can be added as needed. -ACCURATE
ANSWER valid values. Example: If a significantly distinct type of device is used
in a new procedure, a new device value can be added to the system.
,As with words in their context, the meaning of any single value is a combination of
its ____. -ACCURATE ANSWER axis of classification and any preceding values
on which it may be dependent. Example: The meaning of a body part value in the
Medical and Surgical section is always dependent on the body system value. The
body part value 0 in the Central Nervous body system specifies Brain and the body
part value 0 in the Peripheral Nervous body system specifies Cervical Plexus.
True or False? As the system is expanded to become increasingly detailed, over
time more values will depend on preceding values for their meaning. -ACCURATE
ANSWER True. Example: In the Lower Joints body system, the device value 3 in
the root operation Insertion specifies Infusion Device and the device value 3 in the
root operation Replacement specifies Ceramic Synthetic Substitute.
What is the purpose of the Alphabetic Index? -ACCURATE ANSWER To locate
the appropriate table that contains all information necessary to construct a
procedure code
What should always be consulted to find the most appropriate valid code? -
ACCURATE ANSWER the PCS tables
What is not required to be consulted first before proceeding to the tables to
complete the code? -ACCURATE ANSWER the index
Where must a valid code be chosen? -ACCURATE ANSWER directly from the
tables.
How many characters must be specified to be a valid code? -ACCURATE
ANSWER All seven characters
, What should a coder do if the document is incomplete for coding purposes? -
ACCURATE ANSWER the physician should be queried for the necessary
information.
True or false? You can build a code using characters from any row of the table. -
ACCURATE ANSWER False. Within a PCS table, valid codes include all
combinations of choices in characters 4 through 7 contained in the same row of the
table. In the example below, 0JHT3VZ is a valid code, and 0JHW3VZ is not a
valid code
What does "and"mean? -ACCURATE ANSWER means "and/or," except when
used to describe a combination of multiple body parts for which separate values
exist for each body part (e.g., Skin and Subcutaneous Tissue used as a qualifier,
where there are separate body part values for "Skin" and "Subcutaneous Tissue").
Example: Lower Arm and Wrist Muscle means lower arm and/or wrist muscle.
True or false?The physician has to use PCS terms. -ACCURATE ANSWER False.-
terms used to construct PCS codes are defined within the system. - It is the coder's
responsibility to determine what the documentation in the medical record equates
to in the PCS definitions. - only query the physician when the documentation in
relation to the defined PCS terms is unclear. Example: When the physician
documents "partial resection" the coder can independently correlate "partial
resection" to the root operation Excision without querying the physician for
clarification
Where can the procedure codes in the Anatomical Regions, General Anatomical
Regions, Upper Extremities and Anatomical regions, lower Extremitiesbe used? -
ACCURATE ANSWER when the procedure is performed on an anatomical region
rather than a specific body part, or on the rare occasion when no information is
available to support assignment of a code to a specific body part. Examples: Chest
tube drainage of the pleural cavity is coded to the root operation Drainage found in
