EXERCISES
EXERCISE 6.1: OVERVIEW OF ICD-10-PCS
1. ICD-10-PCS was developed by CMS for use in hospital settings only.
Answer: inpatient
Analysis: ICD-10-PCS was developed by the CMS for use in inpatient hospital
settings only. CPT and HCPCS level II are used by all other health care settings,
such as hospital outpatient, home health, hospice, long term care (e.g., skilled
nursing facility), and physician ofiice settings.
2. ICD-10-PCS codes are reported for surgical .
Answer: procedures
Analysis: ICD-10-PCS codes are reported for surgical procedures (in inpatient
hospital settings only). While CPT and HCPCS level II codes are also reported for
procedures (and services), they are used in other than inpatient hospital settings.

, 3. ICD-10-PCS contains unique codes for all substantially different procedures, which
is a major attribute that results in a (or comprehensive) classification.
Answer: complete
Analysis: ICD-10-PCS contains unique codes for all substantially different procedures,
which is a major attribute that results in a complete (or comprehensive) classification.
4. As new procedures are developed, additional unique ICD-10-PCS codes are easily
added and incorporated to facilitate as a major attribute.
Answer: expandability
Analysis: As new procedures are developed, additional unique ICD-10-PCS codes are
easily added and incorporated to facilitate expandability as a major attribute.
5. A valid 7-character ICD-10-PCS alphanumeric code is constructed using a
structure (or axis of classification) as a major attribute.
Answer: multiaxial
Analysis: A valid 7-character ICD-10-PCS alphanumeric code is constructed using a
multiaxial structure (or axis of classification) as a major attribute.
6. A unique vocabulary was developed for ICD-10-PCS as a major attribute, using
terminology.
Answer: standardized
Analysis: A unique vocabulary was developed for ICD-10-PCS as a major attribute, using
standardized terminology. For example, root operations are defined in the ICD-10-PCS
tables.
7. Diagnostic information is not included in ICD-10-PCS code descriptions; instead,
diseases and injuries are assigned codes.
Answer: ICD-10-CM
Analysis: Diagnostic information is not included in ICD-10-PCS code descriptions;
instead, diseases and injuries are assigned ICD-10-CM codes.
8. The ICD-10-PCS classification’s level of specificity includes codes for all procedures
currently performed, resulting in construction of and valid codes.
Answer: unique
Analysis: The ICD-10-PCS classification’s level of specificity includes codes for all
procedures currently performed, resulting in construction of unique and valid codes.
9. Each April 1 and October 1, ICD-10-CM and codes are updated
immediately so that accurate codes are reported on submitted inpatient hospital
claims.

, Analysis: Each April 1 and October 1, ICD-10-CM and ICD-10-PCS codes are updated
immediately so that accurate codes are reported on submitted inpatient hospital claims.
10. ICD-10-PCS codes are reported on the (or CMS-1450) claim.
Answer: UB-04
Analysis: ICD-10-PCS codes are reported on the UB-04 (or CMS-1450) claim.
EXERCISE 6.2: ICD-10-PCS INDEX
6.2 A: Completion
1. The ICD-10-PCS index is an alphabetical listing of procedures that usually includes
the first 3–6 (and sometimes all 7) of the procedure code.
Answer: characters
Analysis: The ICD-10-PCS index is an alphabetical listing of procedures that usually
includes the first 3–6 characters of the procedure code. The rest of the seven-
character code is constructed by using the appropriate ICD-10-PCS table, where the
values (terms) associated with each character are found.
2. When the index provides a seven-character code, the coder should always consult
the appropriate ICD-10-PCS to verify that the code is valid.
Answer: table
Analysis: When the index provides a seven-character code, the coder should always
consult the appropriate ICD-10-PCS table to verify the validity of the code.
3. It is not possible to construct a procedure code by using just the ICD-10-PCS .
Answer: index
Analysis: It is not possible to construct a procedure code by using just the ICD -10-
PCS index. Even when a seven-character code is provided in the index, the
appropriate
ICD-10-PCS table must be used to verify the validity of the code.
4. The Medical and Surgical section tables are referenced by locating
operations as main terms in the ICD-10-PCS index.
Answer: root
Analysis: The Medical and Surgical section tables are referenced by locating root
operations as main terms in the ICD-10-PCS index. For example, root operations
excision, replacement, and resection are found in the ICD-10-PCS index.
5. Coders are directed to the appropriate root operation as the main term in the ICD-10-
PCS index for surgical procedures such as Appendectomy, which is considered a
procedure term.
