Summary
These codes represent different levels of the same hierarchy: S61.204 is the non-billable header that contains S61.204D, so only S61.204D (or a sibling) is reported.
Registry fact- What is different?
Title wording and billing status.S61.204D’s title adds “subsequent encounter” to the wording the two share (“Unspecified open wound of right ring finger without damage to nail”). S61.204 is a non-billable header; S61.204D is billable.
Registry fact
- Can these codes be reported together?
Not as a pair.S61.204 is the non-billable header that contains S61.204D. A header is not reported on a claim, so the choice is S61.204D 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. S61.204 carries 3 Excludes1 notes and S61.204D 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. S61.204 carries 4 Excludes2 notes and S61.204D carries 4 Excludes2 notes covering other codes; the side-by-side table quotes them.
Official rule
- Is one more specific?
Yes.S61.204D is a subdivision of S61.204 in the tabular hierarchy, so it is the more specific of the two.
Registry fact
- Is one a parent or header code?
Yes.S61.204 is the non-billable header that contains S61.204D. 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 — S61.204 is not reportable. S61.204 is the non-billable category that contains S61.204D.
A header stands for the whole family of codes beneath it and is not reported on a claim, so the choice is S61.204D 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: S61.204 and S61.204D
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.
