S62.90XK — Unspecified fracture of unspecified hand, subsequent encounter for fracture with nonunion
Is S62.90XK billable?
Yes, but S62.90XK will trip a Medicare edit. S62.90XK is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S62.90XK 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.

Which MS-DRGs does S62.90XK group to?
S62.90XK 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.

How is S62.90XK listed in the Alphabetic Index?
The Alphabetic Index lists these routes under S62.9, the nearest indexed parent of S62.90XK. Use them to find the family, then select the specific code.
- Fracture, traumatic › hand (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from S62
The conditions below can never be reported together with S62.90XK 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 wrist and hand (S68.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S62.90XK to fully describe the condition. S62.90XK 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 S62.90XK, but a patient may have both at the same time. When documentation supports it, S62.90XK and the excluded code may both be reported.
Excludes2 — not included here — inherited from S60-S69
The conditions below are not part of S62.90XK, but a patient may have both at the same time. When documentation supports it, S62.90XK and the excluded code may both be reported.
