- Is there an Excludes1 relationship?
None.Neither entry carries an Excludes1 note that names the other code. V91.39XA carries 2 Excludes1 notes and V91.39XS carries 2 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. V91.39XA carries 2 Excludes2 notes and V91.39XS carries 2 Excludes2 notes covering other codes; the side-by-side table quotes them.

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. V91.39XA and V91.39XS 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.
