About S42.034S

S42.034S is the ICD-10-CM diagnosis code for nondisplaced fracture of lateral end of right clavicle, sequela. It belongs to category S42 (fracture of shoulder and upper arm), block S40-S49 (injuries to the shoulder and upper arm) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

The 7th character "S" means sequela: use it for complications or conditions that arise as a direct result of the original condition.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 559 (Aftercare, Musculoskeletal System and Connective Tissue with MCC, relative weight 1.8088), DRG 560 (Aftercare, Musculoskeletal System and Connective Tissue with CC, relative weight 1.1238) and DRG 561 (Aftercare, Musculoskeletal System and Connective Tissue without CC/MCC, relative weight 0.8258), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 905.2 (late effect of fracture of upper extremities).
