ICD-10-CM Code G72.9

Myopathy, unspecified

Version 2020 Billable Code

Valid for Submission

G72.9 is a billable code used to specify a medical diagnosis of myopathy, unspecified. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code G72.9 might also be used to specify conditions or terms like chronic intestinal pseudo-obstruction or hollow visceral myopathy or myopathic facies or proximal myopathy.

Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Chronic intestinal pseudo-obstruction
  • Hollow visceral myopathy
  • Myopathic facies
  • Proximal myopathy

Clinical Information

  • INTESTINAL PSEUDO OBSTRUCTION-. a type of ileus a functional not mechanical obstruction of the intestines. this syndrome is caused by a large number of disorders involving the smooth muscles muscle smooth or the nervous system.
  • KEARNS SAYRE SYNDROME-. a mitochondrial disorder featuring the triad of chronic progressive external ophthalmoplegia cardiomyopathy cardiomyopathies with conduction block heart block and retinitis pigmentosa. disease onset is in the first or second decade. elevated csf protein sensorineural deafness seizures and pyramidal signs may also be present. ragged red fibers are found on muscle biopsy. adams et al. principles of neurology 6th ed p984
  • MUSCULAR DISEASES-. acquired familial and congenital disorders of skeletal muscle and smooth muscle.
  • MYOSITIS-. inflammation of a muscle or muscle tissue.
  • MYOTONIC DYSTROPHY-. neuromuscular disorder characterized by progressive muscular atrophy; myotonia and various multisystem atrophies. mild intellectual disability may also occur. abnormal trinucleotide repeat expansion in the 3' untranslated regions of dmpk protein gene is associated with myotonic dystrophy 1. dna repeat expansion of zinc finger protein 9 gene intron is associated with myotonic dystrophy 2.
  • MYOTONIA CONGENITA-. inherited myotonic disorders with early childhood onset myotonia. muscular hypertrophy is common and myotonia may impair ambulation and other movements. it is classified as thomsen autosomal dominant or becker autosomal recessive generalized myotonia mainly based on the inheritance pattern. becker type is also clinically more severe. an autosomal dominant variant with milder symptoms and later onset is known as myotonia levior. mutations in the voltage dependent skeletal muscle chloride channel are associated with the disorders.
  • MITOCHONDRIAL MYOPATHIES-. a group of muscle diseases associated with abnormal mitochondria function.
  • MELAS SYNDROME-. a mitochondrial disorder characterized by focal or generalized seizures episodes of transient or persistent neurologic dysfunction resembling strokes and ragged red fibers on muscle biopsy. affected individuals tend to be normal at birth through early childhood then experience growth failure episodic vomiting and recurrent cerebral insults resulting in visual loss and hemiparesis. the cortical lesions tend to occur in the parietal and occipital lobes and are not associated with vascular occlusion. vascular headache is frequently associated and the disorder tends to be familial. from joynt clinical neurology 1992 ch56 p117
  • OPHTHALMOPLEGIA CHRONIC PROGRESSIVE EXTERNAL-. a mitochondrial myopathy characterized by slowly progressive paralysis of the levator palpebrae orbicularis oculi and extraocular muscles. ragged red fibers and atrophy are found on muscle biopsy. familial and sporadic forms may occur. disease onset is usually in the first or second decade of life and the illness slowly progresses until usually all ocular motility is lost. from adams et al. principles of neurology 6th ed p1422
  • MYOPATHIES NEMALINE-. a group of inherited congenital myopathic conditions characterized clinically by weakness hypotonia and prominent hypoplasia of proximal muscles including the face. muscle biopsy reveals large numbers of rod shaped structures beneath the muscle fiber plasma membrane. this disorder is genetically heterogeneous and may occasionally present in adults. adams et al. principles of neurology 6th ed p1453
  • MYOSITIS INCLUSION BODY-. progressive myopathies characterized by the presence of inclusion bodies on muscle biopsy. sporadic and hereditary forms have been described. the sporadic form is an acquired adult onset inflammatory vacuolar myopathy affecting proximal and distal muscles. familial forms usually begin in childhood and lack inflammatory changes. both forms feature intracytoplasmic and intranuclear inclusions in muscle tissue. adams et al. principles of neurology 6th ed pp1409 10
  • MUSCULAR DYSTROPHY EMERY DREIFUSS-. a heterogenous group of inherited muscular dystrophy without the involvement of nervous system. the disease is characterized by muscular atrophy; muscle weakness; contracture of the elbows; achilles tendon; and posterior cervical muscles; with or without cardiac features. there are several inheritance patterns including x linked x chromosome autosomal dominant and autosomal recessive gene mutations.
  • MYOPATHY CENTRAL CORE-. an inherited congenital myopathic condition characterized by weakness and hypotonia in infancy and delayed motor development. muscle biopsy reveals a condensation of myofibrils and myofibrillar material in the central portion of each muscle fiber. adams et al. principles of neurology 6th ed p1452
  • MYOPATHIES STRUCTURAL CONGENITAL-. a heterogeneous group of diseases characterized by the early onset of hypotonia developmental delay of motor skills non progressive weakness. each of these disorders is associated with a specific histologic muscle fiber abnormality.
  • MYOTONIC DISORDERS-. diseases characterized by myotonia which may be inherited or acquired. myotonia may be restricted to certain muscles e.g. intrinsic hand muscles or occur as a generalized condition.
  • DISTAL MYOPATHIES-. a heterogeneous group of genetic disorders characterized by progressive muscular atrophy and muscle weakness beginning in the hands the legs or the feet. most are adult onset autosomal dominant forms. others are autosomal recessive.

Information for Patients


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 is not known.
