S32.401K — Unspecified fracture of right acetabulum, subsequent encounter for fracture with nonunion
Is S32.401K billable?
Yes, but S32.401K is an unspecified code. S32.401K is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S32.401K 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 S32.401K — the more specific alternatives are listed below.

What does the 7th character "K" mean in S32.401K?
In S32.401K, the 7th character K means subsequent encounter for fracture with nonunion. The 7th character is required for S32.401K to be a valid, complete code.
Same condition, different episode of care — switch the 7th character:
Which MS-DRGs does S32.401K group to?
S32.401K 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.
- 521Hip Replacement with Principal Diagnosis of Hip Fracture with MCCsurgical
- 522Hip Replacement with Principal Diagnosis of Hip Fracture without MCCsurgical
As a secondary diagnosis, S32.401K is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is S32.401K listed in the Alphabetic Index?
The Alphabetic Index lists these routes under S32.40, the nearest indexed parent of S32.401K. Use them to find the family, then select the specific code.
- Fracture, traumatic › acetabulum (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from S32
The conditions below can never be reported together with S32.401K on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- transection of abdomen (S38.3)
Code first — inherited from S32
The underlying condition below must be sequenced before S32.401K. S32.401K describes a manifestation and cannot be the principal or first-listed diagnosis.
- any associated spinal cord and spinal nerve injury (S34.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S32.401K to fully describe the condition. S32.401K 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 S32.401K, but a patient may have both at the same time. When documentation supports it, S32.401K and the excluded code may both be reported.
Excludes2 — not included here — inherited from S30-S39
The conditions below are not part of S32.401K, but a patient may have both at the same time. When documentation supports it, S32.401K and the excluded code may both be reported.
Excludes2 — not included here — inherited from S32
The conditions below are not part of S32.401K, but a patient may have both at the same time. When documentation supports it, S32.401K and the excluded code may both be reported.
- fracture of hip NOS (S72.0-)
Code also — inherited from S32.4
Two codes may be needed to describe the condition fully. Whether S32.401K is sequenced first depends on the reason for the encounter.
- any associated fracture of pelvic ring (S32.8-)
How long has S32.401K existed?
S32.401K 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.
