S92.146K — Nondisplaced dome fracture of unspecified talus, subsequent encounter for fracture with nonunion
Is S92.146K billable?
Yes, but S92.146K will trip a Medicare edit. S92.146K is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S92.146K under Medicare Code Editor edit 20, “Unspecified code” — meaning a code specifying laterality (right, left or bilateral) exists in the same family. On an inpatient claim this triggers the edit, because CMS holds that there are very limited circumstances in which laterality cannot be documented.

What Medicare edits apply to S92.146K?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name S92.146K directly.
A code specifying laterality (right, left or bilateral) exists in the same family. CMS holds that there are very limited circumstances in which laterality cannot be documented.
Which MS-DRGs does S92.146K group to?
S92.146K 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.

- 565Other Musculoskeletal System and Connective Tissue Diagnoses with CCmedical
- 566Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCCmedical
As a secondary diagnosis, S92.146K is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from S92.14
The conditions below can never be reported together with S92.146K on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- osteochondritis dissecans (M93.2)
Use additional code — inherited from Chapter 19
Report an additional code alongside S92.146K to fully describe the condition. S92.146K 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 S92.146K, but a patient may have both at the same time. When documentation supports it, S92.146K and the excluded code may both be reported.
Excludes2 — not included here — inherited from S90-S99
The conditions below are not part of S92.146K, but a patient may have both at the same time. When documentation supports it, S92.146K and the excluded code may both be reported.
Excludes2 — not included here — inherited from S92

How long has S92.146K existed?
S92.146K 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.
