S82.301C — Unspecified fracture of lower end of right tibia, initial encounter for open fracture type IIIA, IIIB, or IIIC
Is S82.301C billable?
Yes, but S82.301C is an unspecified code. S82.301C is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S82.301C is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting S82.301C — the more specific alternatives are listed below.

Which MS-DRGs does S82.301C group to?
S82.301C sits in MDC 08 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 562Fracture, Sprain, Strain and Dislocation Except Femur, Hip, Pelvis and Thigh with MCCmedical
- 563Fracture, Sprain, Strain and Dislocation Except Femur, Hip, Pelvis and Thigh without MCCmedical
As a secondary diagnosis, S82.301C is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG. It also carries Hospital-Acquired Condition category 05.
How is S82.301C listed in the Alphabetic Index?
The Alphabetic Index lists these routes under S82.30, the nearest indexed parent of S82.301C. Use them to find the family, then select the specific code.
- Fracture, traumatic › tibia › lower end (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from S82
The conditions below can never be reported together with S82.301C on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- traumatic amputation of lower leg (S88.-)
Excludes1 — never code together — inherited from S82.3
The conditions below can never be reported together with S82.301C on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from Chapter 19
Report an additional code alongside S82.301C to fully describe the condition. S82.301C is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of S82.301C, but a patient may have both at the same time. When documentation supports it, S82.301C and the excluded code may both be reported.
Excludes2 — not included here — inherited from S80-S89
The conditions below are not part of S82.301C, but a patient may have both at the same time. When documentation supports it, S82.301C and the excluded code may both be reported.
Excludes2 — not included here — inherited from S82

How long has S82.301C existed?
S82.301C has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
