7th Character Guide
"The appropriate 7th character is to be added to each code from category S76"
- A — initial encounter
- D — subsequent encounter
- S — sequela
How the encounter character is assigned. “Initial encounter” means the patient is receiving active treatment for the condition — it is not limited to the first visit, and a different or new provider giving active treatment still assigns it. “Subsequent encounter” covers care during the healing or recovery phase after active treatment. “Sequela” is for complications or conditions that arise as a direct result of the original condition.
ICD-10-CM Official Guidelines for Coding and Reporting, Section I.C.19.a (paraphrased by MedCoder).
Variant codes in this family
Character meanings are CMS's official 7th-character extensions for this family, as carried in each variant code's official description; variant codes are registry rows. The explanation of how the encounter character is assigned is MedCoder editorial, distinct from the official content above it.
Coder workflow for S76.999
MedCoder structured workflow — derived from this code’s own official record
Before you code S76.999
- S76.999 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).
See the relationships section · Guide: How to choose an ICD-10-CM code →
- Unspecified does not mean incorrect. When the record gives no greater specificity, S76.999 may be the appropriate code. Check the record for detail that supports a more specific sibling. An unspecified code is for records that do not provide the detail a more specific code needs; a query, not an assumption, is the route to specificity (Guidelines I.A.9.b, I.B.18).
See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →
- A 7th character is required in this family. Confirm the documented encounter: initial (active treatment), subsequent (healing or recovery phase), or sequela. S76.999 is not valid without one. “Initial” means active treatment, not the first visit (Guidelines I.C.19.a).
See the 7th Character Guide · Guide: 7th characters: initial, subsequent, sequela →
- Laterality is coded in this family. Confirm the side documented — right, left, or bilateral — and select the matching code (this page’s code: unspecified). The unspecified-side code applies only when the record states no side. Laterality is assigned from the documented side; where a bilateral code exists and both sides are documented, it is used instead of two unilateral codes (Guidelines I.B.13).
- Confirm the injury type, the anatomical site at the most specific level documented, laterality where the family codes it, and the encounter for the 7th character. Each injury is coded separately unless the classification provides a combination code, and a superficial injury is not coded when a more severe injury of the same site is documented. Injury chapter guidelines (Guidelines I.C.19.b, I.C.19.b.1).
Choose the right path
- Does the documentation support one of the more specific codes beneath S76.999?
Yes → Select that code and continue the checks below on its own page.
No → S76.999 cannot be reported as written; query for the specificity its subcategory needs. - Does the record document the detail a more specific sibling code needs?
Yes → Review the specific siblings in this subcategory.
No → Continue — S76.999 is appropriate when the documentation goes no further. - Is the side documented?
Yes → Select the code for the documented side (or the bilateral code when both sides are documented and one exists).
No → Use the unspecified-side code only when the record states no side; a query is the alternative. - Is the encounter phase documented — active treatment, healing or recovery, or a sequela?
Yes → Assign the matching 7th character; the variant codes are in the 7th Character Guide.
No → The code is invalid without its 7th character — query for the missing element.
Consider S76.999. Then review the Code Also note, and confirm the code is valid for the date of service in the Verify section.
Documentation check
- The provider’s diagnostic statement
- Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
- Anatomical site
- At the most specific level the record states; a site the classification separates cannot be assumed from a procedure or a measurement.
- Laterality
- Right, left or bilateral as documented; unspecified only when the record states no side (Guidelines I.B.13).
- Encounter type
- Active treatment, healing or recovery phase, or sequela — the basis of the 7th character (Guidelines I.C.19.a).
- External cause, place and activity
- For the external cause codes reported with the injury or poisoning, where documented (Guidelines I.C.20.a).
- Any detail beyond this code’s title
- What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.
Official instructions as workflow

Coding workflow: The conditions named in this note are not included in S76.999. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Code Also — related condition(1 note)
Coding workflow: Review the related condition when both are documented and the instruction applies. A Code Also note does not fix sequencing; the order follows the circumstances of the encounter.

Coding decision scenarios
Pattern scenarios for this code’s structure — decision rules, not clinical cases
Documentation: The provider documents the condition in the terms of this code’s title and records no further detail.
Coding question: Is a more specific sibling code supportable?
Path: Review the subcategory for a sibling that names the missing detail.
Reason: A more specific code needs documentation of the distinguishing element; without it the unspecified code is appropriate, and a provider query is the route to specificity (Guidelines I.A.9.b, I.B.18).
Documentation: The patient returns during the healing or recovery phase after active treatment of the same condition.
Coding question: Which 7th character applies?
Path: Review the official 7th-character definitions for this family in the 7th Character Guide.
Reason: “Initial encounter” means active treatment, not the first visit; care during recovery takes “subsequent encounter”, and a complication arising from the original condition takes “sequela” (Guidelines I.C.19.a).
Documentation: The record documents the condition on one side only.
Coding question: Which code in this family applies?
Path: Select the sibling code for the documented side.
Reason: Laterality is assigned from the documented side; the unspecified-side code is for records that state no side (Guidelines I.B.13).

Decision Points
The directives on this code's own record, as a pre-claim checklist.
- A 7th character applies in this family. Confirm the documented encounter matches the character assigned. See the official 7th-character definitions and this code’s variants
- 1 Code Also note — a second code may apply; the guidelines leave its sequencing to the circumstances of the encounter. See the Code Also notes
- 6 Excludes2 entries — those conditions are not part of this code and may be reported additionally when documented. See the Excludes2 notes
Checklist rows are derived from this code's own official directives; the wording of each check is MedCoder editorial. The official notes themselves are in the sections each row links to.

Common coding questions
Can S76.999 be billed directly?
No. S76.999 (Other specified injury of unspecified muscles, fascia and tendons at thigh level, unspecified thigh) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
Does S76.999 require a 7th character?
Yes. The appropriate 7th character is to be added to each code from category S76.
