Which MS-DRGs does S82.432N group to?
S82.432N sits in MDC 08 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 564Other Musculoskeletal System and Connective Tissue Diagnoses with MCCmedical
- 565Other Musculoskeletal System and Connective Tissue Diagnoses with CCmedical
- 566Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCCmedical
As a secondary diagnosis, S82.432N is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

- Fracture, traumatic › fibula › oblique › nondisplaced (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from S82
The conditions below can never be reported together with S82.432N 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.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S82.432N to fully describe the condition. S82.432N 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 S82.432N, but a patient may have both at the same time. When documentation supports it, S82.432N and the excluded code may both be reported.
Excludes2 — not included here — inherited from S80-S89
The conditions below are not part of S82.432N, but a patient may have both at the same time. When documentation supports it, S82.432N and the excluded code may both be reported.
Excludes2 — not included here — inherited from S82
The conditions below are not part of S82.432N, but a patient may have both at the same time. When documentation supports it, S82.432N and the excluded code may both be reported.
Excludes2 — not included here — inherited from S82.4
The conditions below are not part of S82.432N, but a patient may have both at the same time. When documentation supports it, S82.432N and the excluded code may both be reported.
- fracture of lateral malleolus alone (S82.6-)
How long has S82.432N existed?
S82.432N 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.
