V91.20XA vs V91.20XS
V91.20XA (Fall due to collision between merchant ship and other watercraft or other object, initial encounter) compared with V91.20XS (Fall due to collision between merchant ship and other watercraft or other object, sequela), from the official CMS tabular data.
Summary
No tabular note links these codes. Both belong to category V91, and nothing in the tabular list prevents reporting each when it is documented.
Registry fact- What is different?
Title wording.The titles share “Fall due to collision between merchant ship and other watercraft or other object”; V91.20XA says “initial encounter” where V91.20XS 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 V91; 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. V91.20XA carries 4 Excludes1 notes and V91.20XS carries 4 Excludes1 notes 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. V91.20XA carries 1 Excludes2 note and V91.20XS carries 1 Excludes2 note covering other codes; the side-by-side table quotes them.
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 V91.
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. V91.20XA and V91.20XS both belong to category V91.
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.
