About M00.87

M00.87 is the ICD-10-CM diagnosis code for arthritis due to other bacteria, ankle and foot. It belongs to category M00 (pyogenic arthritis), block M00-M02 (infectious arthropathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within M00.8, choose M00.87 (Arthritis due to other bacteria, ankle and foot) only when documentation doesn't support a more specific option: arthritis due to other bacteria, unspecified joint (M00.80), arthritis due to other bacteria, shoulder (M00.81), arthritis due to other bacteria, elbow (M00.82), arthritis due to other bacteria, wrist (M00.83), arthritis due to other bacteria, hand (M00.84), arthritis due to other bacteria, hip (M00.85), arthritis due to other bacteria, knee (M00.86), arthritis due to other bacteria, vertebrae (M00.88) and 1 more.

To report this condition, pick the subcode that matches the documentation: M00.871 (foot), M00.872 (foot) and M00.879 (foot).

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