R40.24 vs R40.2410
R40.24 (Glasgow coma scale, total score) compared with R40.2410 (Glasgow coma scale score 13-15, unspecified time), from the official CMS tabular data.
Summary
These codes represent different levels of the same hierarchy: R40.24 is the non-billable header that contains R40.2410, so only R40.2410 (or a sibling) is reported.
Registry fact- What is different?
Title wording and billing status.The titles share “Glasgow coma scale”; R40.24 says “total score” where R40.2410 says “score 13-15, unspecified time”. R40.24 is a non-billable header; R40.2410 is billable.
Registry fact
- Can these codes be reported together?
Not as a pair.R40.24 is the non-billable header that contains R40.2410. A header is not reported on a claim, so the choice is R40.2410 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. R40.24 carries 4 Excludes1 notes and R40.2410 carries 4 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. R40.24 carries 1 Excludes2 note and R40.2410 carries 1 Excludes2 note covering other codes; the side-by-side table quotes them.
Official rule
- Is one more specific?
Yes.R40.2410 is a subdivision of R40.24 in the tabular hierarchy, so it is the more specific of the two.
Registry fact
- Is one a parent or header code?
Yes.R40.24 is the non-billable header that contains R40.2410. 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 — R40.24 is not reportable. R40.24 is the non-billable category that contains R40.2410.
A header stands for the whole family of codes beneath it and is not reported on a claim, so the choice is R40.2410 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: R40.24 and R40.2410
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.
