M70.8Other soft tissue disorders related to use, overuse and pressure

M70.8 is the ICD-10-CM diagnosis code for other soft tissue disorders related to use, overuse and pressure. It belongs to category M70 (soft tissue disorders related to use, overuse and pressure), block M70-M79 (other soft tissue disorders) 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 10 subcodes must be used instead.

Within M70, choose M70.8 (Other soft tissue disorders related to use, overuse and pressure) only when documentation doesn't support a more specific option: Crepitant synovitis (acute) (chronic) of hand and wrist (M70.0), bursitis of hand (M70.1), olecranon bursitis (M70.2), other bursitis of elbow (M70.3), Prepatellar bursitis (M70.4), other bursitis of knee (M70.5), trochanteric bursitis (M70.6), other bursitis of hip (M70.7) and 1 more.

To report this condition, pick the subcode that matches the documentation: M70.80 (of unspecified site), M70.81 (of shoulder), M70.82 (of upper arm), M70.83 (of forearm), M70.84 (of hand), M70.85 (of thigh), M70.86 (lower leg), M70.87 (of ankle and foot) and 2 more.

Use an additional code for: external cause code to identify activity causing disorder (Y93.-).

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