S06.0X1D vs S06.81
S06.0X1D (Concussion with loss of consciousness of 30 minutes or less, subsequent encounter) compared with S06.81 (Injury of right internal carotid artery, intracranial portion, not elsewhere classified), from the official CMS tabular data.
Summary
No tabular note links these codes. Both belong to category S06, and nothing in the tabular list prevents reporting each when it is documented.
Registry fact- What is different?
The conditions named and billing status.S06.0X1D is “Concussion with loss of consciousness of 30 minutes or less, subsequent encounter”; S06.81 is “Injury of right internal carotid artery, intracranial portion, not elsewhere classified”. S06.81 is a non-billable header; S06.0X1D is billable.
Registry fact
- Can these codes be reported together?
No instruction prevents it.No note in either entry names the other. Both belong to category S06; 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. S06.0X1D carries 2 Excludes1 notes and S06.81 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. S06.0X1D carries 9 Excludes2 notes and S06.81 carries 9 Excludes2 notes 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 S06.
Registry fact
- Is one a parent or header code?
One is a header.S06.81 is a non-billable header, but S06.0X1D is not one of its subdivisions.
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. S06.0X1D and S06.81 both belong to category S06.
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.
