Summary
No tabular note links these codes. Both belong to category V90, and nothing in the tabular list prevents reporting each when it is documented.
Registry fact- What is different?
Title wording.The titles share “Drowning and submersion due to unspecified watercraft overturning”; V90.09XA says “initial encounter” where V90.09XS says “sequela”.
Registry fact
Nothing found in 7 other checks
- Can these codes be reported together?
No instruction prevents it.No note in either entry names the other. Both belong to category V90; 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. V90.09XA carries 4 Excludes1 notes and V90.09XS 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.
Official rule
- Is one more specific?
No.Both titles are unspecified forms within category V90, and neither is a subdivision of the other.
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. V90.09XA and V90.09XS both belong to category V90.
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.
Side by side
Similar descriptions do not make codes interchangeable. The documentation and the official instructions decide which code applies.

No Excludes2, Code first, Use additional code and Code also note at either code.
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. In a row that differs, each code’s own notes are listed under it, and the notes every code shares are listed once beneath them.
