Clinical Classification

Clinical Information

  • 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)
  • Asthenia

    clinical sign or symptom manifested as debility, or lack or loss of strength and energy.
  • Neurocirculatory Asthenia

    a clinical syndrome characterized by palpitation, shortness of breath, labored breathing, subjective complaints of effort and discomfort, all following slight physical exertion. other symptoms may be dizziness, tremulousness, sweating, and insomnia. neurocirculatory asthenia is most typically seen as a form of anxiety disorder.
  • Dropped Head Syndrome

    condition characterized by sagging of the head due to severe neck muscles weakness in the back of the neck. it may result in severe cervical kyphosis called chin-on-chest deformity. dropped head syndrome is most often associated with other diseases, e.g., parkinson's disease; strokes; head and neck cancer; and ankylosing spondylitis.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 1 Excludes

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.

Patient Education


Muscle Disorders

Your muscles help you move and help your body work. Different types of muscles have different jobs. There are many problems that can affect muscles. Muscle disorders can cause weakness, pain or even paralysis.

Causes of muscle disorders include:

  • Injury or overuse, such as sprains or strains, cramps or tendinitis
  • A genetic disorder, such as muscular dystrophy
  • Some cancers
  • Inflammation, such as myositis
  • Diseases of nerves that affect muscles
  • Infections
  • Certain medicines

Sometimes the cause of muscle disorders is unknown.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
