Summary
No coding relationship between these codes was found in the tabular notes or in MedCoder’s derived relationships.
- What is different?
The conditions named, billing status and chapter.T86.2 is “Complications of heart transplant”; Z94.1 is “Heart transplant status”. T86.2 is a non-billable header; Z94.1 is billable. T86.2 sits in S00-T88 — Injury, Poisoning and Certain Other Consequences of External Causes (S00-T88); Z94.1 in Z00-Z99 — Factors Influencing Health Status and Contact with Health Services (Z00-Z99).
Registry fact
- Is one a parent or header code?
One is a header.T86.2 is a non-billable header, but Z94.1 is not one of its subdivisions.
Registry fact
Nothing found in 5 other checks; 1 check does not apply
- Can these codes be reported together?
No instruction prevents it.No note in either entry names the other, and no derived relationship links them. Each may be reported when its own documentation requirements are met.
Registry fact
- Is there an Excludes1 relationship?
None.Neither entry carries an Excludes1 note that names the other code. T86.2 carries 3 Excludes1 notes and Z94.1 carries 3 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. T86.2 carries 21 Excludes2 notes and Z94.1 carries 1 Excludes2 note covering other codes; the side-by-side table quotes them.
Official rule
- Is one more specific?
Not comparable.The codes sit in different categories; specificity is only comparable within one category.
- 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.
No Excludes1/Excludes2 relationship exists between these codes in the official tabular list. Each may be reported when its own documentation requirements are met.
Side by side
Similar descriptions do not make codes interchangeable. The documentation and the official instructions decide which code 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. 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.
