V21.01XD vs V21.01XS
V21.01XD (Electric (assisted) bicycle driver injured in collision with pedal cycle in nontraffic accident, subsequent encounter) compared with V21.01XS (Electric (assisted) bicycle driver injured in collision with pedal cycle in nontraffic accident, sequela), from the official CMS tabular data.
Summary
No tabular note links these codes. Both belong to category V21, and nothing in the tabular list prevents reporting each when it is documented.
Registry fact- What is different?
Title wording.The titles share “Electric (assisted) bicycle driver injured in collision with pedal cycle in nontraffic accident”; V21.01XD says “subsequent encounter” where V21.01XS says “sequela”.
Registry fact
- Can these codes be reported together?
No instruction prevents it.No note in either entry names the other. Both belong to category V21; each may be reported when its own documentation is present.
Registry fact
- Is there an Excludes1 relationship?
None.Neither entry carries an Excludes1 note that names the other code. V21.01XD carries 1 Excludes1 note and V21.01XS carries 1 Excludes1 note covering other codes; the side-by-side table quotes them.
Official rule
- Is there an Excludes2 relationship?
None.Neither entry carries an Excludes2 note that names the other code.
Official rule
- Is one more specific?
No.Neither is a subdivision of the other, and neither title is the unspecified form; they describe different conditions within category V21.
Registry fact
- Is one a parent or header code?
No.Both are billable codes, and neither contains the other.
Registry fact
- Are there sequencing instructions?
None.Neither entry carries a Code First or Use Additional Code note that names the other.
Official rule
- Are there other coding relationships?
None found.No laterality, encounter-phase, Table of Neoplasms, Table of Drugs and Chemicals, or history-versus-active-disease relationship links these codes.
MedCoder-derived
Official rule: a tabular instructional note or a section of the ICD-10-CM Official Guidelines, quoted as published. Registry fact: the codes’ own published attributes (titles, billable status, position in the hierarchy, code set). MedCoder-derived: a reading MedCoder computes from those facts; it is not itself a rule. How to read the labels
Can these codes be reported together?
Yes, when each is documented. V21.01XD and V21.01XS both belong to category V21.
No Excludes1/Excludes2 relationship exists between these codes in the official tabular list. The code titles state what each one covers, and the documentation decides which applies.

Notes are the code’s own tabular entry, quoted as published. A note that names the other code is the one the verdict above rests on.
