M24.875Other specific joint derangements left foot, not elsewhere classified

M24.875 is the ICD-10-CM diagnosis code for other specific joint derangements left foot, not elsewhere classified. It belongs to category M24 (other specific joint derangements), block M20-M25 (other joint disorders) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M24.87 (other specific joint derangements of ankle and foot, not elsewhere classified), M24.875 is specifically for other specific joint derangements left foot, not elsewhere classified. Related codes cover of right ankle, not elsewhere classified (M24.871), of left ankle, not elsewhere classified (M24.872), of unspecified ankle, not elsewhere classified (M24.873), of right foot, not elsewhere classified (M24.874) and of unspecified foot, not elsewhere classified (M24.876).

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 564 (Other Musculoskeletal System and Connective Tissue Diagnoses with MCC, relative weight 1.4908), DRG 565 (Other Musculoskeletal System and Connective Tissue Diagnoses with CC, relative weight 0.9783) and DRG 566 (Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCC, relative weight 0.7378), 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 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 718.77 (developmental dislocation of joint, ankle and foot) and 718.87 (other joint derangement, not elsewhere classified, ankle and foot).
