About M79.8

M79.8 is the ICD-10-CM diagnosis code for other specified soft tissue disorders. 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 a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within M79, choose M79.8 (Other specified soft tissue disorders) only when documentation doesn't support a more specific option: rheumatism, unspecified (M79.0), myalgia (M79.1), neuralgia and neuritis, unspecified (M79.2), panniculitis, unspecified (M79.3), hypertrophy of (infrapatellar) fat pad (M79.4), residual foreign body in soft tissue (M79.5), pain in limb, hand, foot, fingers and toes (M79.6), Fibromyalgia (M79.7) and 2 more.

To report this condition, pick the subcode that matches the documentation: M79.81 (tissue) and M79.89 (disorders).

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