T81.60 vs T81.60XD
T81.60 (Unspecified acute reaction to foreign substance accidentally left during a procedure) compared with T81.60XD (Unspecified acute reaction to foreign substance accidentally left during a procedure, subsequent encounter), from the official CMS tabular data.
Summary
These codes represent different levels of the same hierarchy: T81.60 is the non-billable header that contains T81.60XD, so only T81.60XD (or a sibling) is reported.
Registry fact- What is different?
Title wording and billing status.T81.60XD’s title adds “subsequent encounter” to the wording the two share (“Unspecified acute reaction to foreign substance accidentally left during a procedure”). T81.60 is a non-billable header; T81.60XD is billable.
Registry fact
- Can these codes be reported together?
Not as a pair.T81.60 is the non-billable header that contains T81.60XD. A header is not reported on a claim, so the choice is T81.60XD 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.
Official rule
- Is there an Excludes2 relationship?
None.Neither entry carries an Excludes2 note that names the other code. T81.60 carries 32 Excludes2 notes and T81.60XD carries 32 Excludes2 notes covering other codes; the side-by-side table quotes them.
Official rule
- Is one more specific?
Yes.T81.60XD is a subdivision of T81.60 in the tabular hierarchy, so it is the more specific of the two.
Registry fact
- Is one a parent or header code?
Yes.T81.60 is the non-billable header that contains T81.60XD. 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 — T81.60 is not reportable. T81.60 is the non-billable category that contains T81.60XD.
A header stands for the whole family of codes beneath it and is not reported on a claim, so the choice is T81.60XD 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: T81.60 and T81.60XD
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.
