About M79.672

M79.672 is the ICD-10-CM diagnosis code for pain in left foot. It belongs to category M79 (other and unspecified soft tissue disorders, not elsewhere classified), block M70-M79 (other soft tissue 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 M79.67 (pain in foot and toes), M79.672 is specifically for pain in left foot. Related codes cover right foot (M79.671), unspecified foot (M79.673), right toe(s) (M79.674), left toe(s) (M79.675) and unspecified toe(s) (M79.676).

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 555 (Signs and Symptoms of Musculoskeletal System and Connective Tissue with MCC, relative weight 1.2913) and DRG 556 (Signs and Symptoms of Musculoskeletal System and Connective Tissue without MCC, relative weight 0.8211), 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 729.5 (pain in limb).
