M24.375Pathological dislocation of left foot, not elsewhere classified

M24.375 is the ICD-10-CM diagnosis code for pathological dislocation of 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 M24.37 (pathological dislocation of ankle and foot, not elsewhere classified), M24.375 is specifically for pathological dislocation of left foot, not elsewhere classified. Related codes cover right ankle, not elsewhere classified (M24.371), left ankle, not elsewhere classified (M24.372), unspecified ankle, not elsewhere classified (M24.373), right foot, not elsewhere classified (M24.374) and unspecified foot, not elsewhere classified (M24.376).

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 562 (Fracture, Sprain, Strain and Dislocation Except Femur, Hip, Pelvis and Thigh with MCC, relative weight 1.398) and DRG 563 (Fracture, Sprain, Strain and Dislocation Except Femur, Hip, Pelvis and Thigh without MCC, relative weight 0.8985), 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 718.27 (pathological dislocation of joint, ankle and foot).
