Summary
No tabular note links these codes. Both belong to category Y01, and nothing in the tabular list prevents reporting each when it is documented.
Registry fact- What is different?
Title wording.The titles share “Assault by pushing from high place”; Y01.XXXA says “initial encounter” where Y01.XXXS 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 Y01; 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. Y01.XXXA carries 3 Excludes1 notes and Y01.XXXS carries 3 Excludes1 notes covering other codes; the side-by-side table quotes them.
Official rule
- Is there an Excludes2 relationship?

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 Y01.

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.

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. Y01.XXXA and Y01.XXXS both belong to category Y01.
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.
