Other disorders of muscle (M62) ICD-10-CM

The M62 code range covers other disorders of muscle with 175 ICD-10-CM diagnosis codes. 131 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the M62 range.

Muscle Weakness

A vague complaint of debility, fatigue, or exhaustion attributable to weakness of various muscles. The weakness can be characterized as subacute or chronic, often progressive, and is a manifestation of many muscle and neuromuscular diseases. (From Wyngaarden et al., Cecil Textbook of Medicine, 19th ed, p2251)

Myotonia

Prolonged failure of muscle relaxation after contraction. This may occur after voluntary contractions, muscle percussion, or electrical stimulation of the muscle. Myotonia is a characteristic feature of MYOTONIC DISORDERS.

Rhabdomyolysis

Necrosis or disintegration of skeletal muscle often followed by myoglobinuria.

Sarcopenia

Progressive decline in muscle mass due to aging which results in decreased functional capacity of muscles.

Spasm

An involuntary contraction of a muscle or group of muscles. Spasms may involve SKELETAL MUSCLE or SMOOTH MUSCLE.

About the M62 Code Range

Muscle problems here include separation or rupture not caused by injury, contracture, wasting, weakness, and spasm.

The first subdivisions distinguish the kind of disorder. M62.0 identifies muscle separation, M62.1 other muscle rupture, and M62.2 nontraumatic ischemic infarction of muscle. M62.3 identifies immobility syndrome, while M62.4 identifies muscle contracture and M62.5 muscle wasting and atrophy.

These groups subdivide mainly by body site, such as shoulder, hand, or lower leg. M62.8 groups other specified muscle disorders, including generalized weakness and spasm. M62.9 identifies an unspecified muscle disorder.
