S92.526P — Nondisplaced fracture of middle phalanx of unspecified lesser toe(s), subsequent encounter for fracture with malunion
Is S92.526P billable?
Yes, but S92.526P will trip a Medicare edit. S92.526P is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S92.526P 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 S92.526P?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name S92.526P 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 S92.526P group to?
S92.526P 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, S92.526P is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is S92.526P listed in the Alphabetic Index?
The Alphabetic Index lists these routes under S92.52, the nearest indexed parent of S92.526P. Use them to find the family, then select the specific code.
- Fracture, traumatic › toe › lesser › middle phalanx (abduction) (adduction) (separation)
- Fracture, traumatic › toe › lesser › middle phalanx › nondisplaced (abduction) (adduction) (separation)
