M79.6Pain in limb, hand, foot, fingers and toes

M79.6 is the ICD-10-CM diagnosis code for pain in limb, hand, foot, fingers and toes. 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 7 subcodes must be used instead.

Within M79 (other and unspecified soft tissue disorders, not elsewhere classified), M79.6 is specifically for pain in limb, hand, foot, fingers and toes. Related codes cover 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), Fibromyalgia (M79.7), other specified soft tissue disorders (M79.8) and 2 more.

To report this condition, pick the subcode that matches the documentation: M79.60 (unspecified), M79.62 (arm), M79.63 (forearm), M79.64 (fingers), M79.65 (thigh), M79.66 (leg) and M79.67 (toes).

The conditions in its Excludes2 note aren't part of M79.6, but may be coded alongside it if the patient has both: pain in joint (M25.5-).

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