Summary
These codes represent different levels of the same hierarchy: X83 is the non-billable header that contains X83.0XXA, so only X83.0XXA (or a sibling) is reported.
Registry fact- What is different?
Title wording and billing status.The titles share “Intentional self-harm by”; X83 says “other specified means” where X83.0XXA says “crashing of aircraft, initial encounter”. X83 is a non-billable header; X83.0XXA is billable.
Registry fact
- Can these codes be reported together?
Not as a pair.X83 is the non-billable header that contains X83.0XXA. A header is not reported on a claim, so the choice is X83.0XXA or a sibling that matches the documentation.
Registry fact
- Is there an Excludes1 relationship?
None.Neither entry carries an Excludes1 note that names the other code. X83 carries 1 Excludes1 note and X83.0XXA 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.
Official rule
- Is one more specific?
Yes.X83.0XXA is a subdivision of X83 in the tabular hierarchy, so it is the more specific of the two.
Registry fact
- Is one a parent or header code?
Yes.X83 is the non-billable header that contains X83.0XXA. A header stands for the whole family beneath it and is not reported on a claim.
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?
Not as a pair — X83 is not reportable. X83 is the non-billable category that contains X83.0XXA.
A header stands for the whole family of codes beneath it and is not reported on a claim, so the choice is X83.0XXA or a sibling that matches the documentation. No Excludes1/Excludes2 relationship exists between these codes in the official tabular list.
Official guidance behind these answers
Section I.B.2 — Level of Detail in Coding · applies to: X83 and X83.0XXA
Diagnosis codes are to be used and reported at their highest number of characters available and to the highest level of specificity documented in the medical record. ICD-10-CM diagnosis codes are composed of codes with 3, 4, 5, 6 or 7 characters. Codes with three characters are included in ICD-10-CM as the heading of a category of codes that may be further subdivided by the use of fourth and/or fifth characters and/or sixth characters, which provide greater detail. A three-character code is to be used only if it is not further subdivided. A code is invalid if it has not been coded to the full number of characters required for that code, including the 7th character, if applicable.

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.
