Code Classification

  • Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified
    (R00–R99)
    • Symptoms and signs involving the nervous and musculoskeletal systems
      (R25-R29)
      • Other lack of coordination
        (R27)

R27 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other lack of coordination. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.

Specific Coding Applicable to Other lack of coordination

Non-specific codes like R27 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for other lack of coordination:

  • Use R27.0 for Ataxia, unspecified - BILLABLE CODE

  • Use R27.8 for Other lack of coordination - BILLABLE CODE

  • Use R27.9 for Unspecified lack of coordination - BILLABLE CODE

Tabular List of Diseases and Injuries

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.
  • ataxic gait R26.0
  • hereditary ataxia G11

Patient Education


Movement Disorders

Movement disorders are neurologic conditions that cause problems with movement, such as:

  • Increased movement that can be voluntary (intentional) or involuntary (unintended)
  • Decreased or slow voluntary movement

There are many different movement disorders. Some of the more common types include:

  • Ataxia, the loss of muscle coordination
  • Dystonia, in which involuntary contractions of your muscles cause twisting and repetitive movements. The movements can be painful.
  • Huntington's disease, an inherited disease that causes nerve cells in certain parts of the brain to waste away. This includes the nerve cells that help to control voluntary movement.
  • Parkinson's disease, which is disorder that slowly gets worse over time. It causes tremors, slowness of movement, and trouble walking.
  • Tourette syndrome, a condition which causes people to make sudden twitches, movements, or sounds (tics)
  • Tremor and essential tremor, which cause involuntary trembling or shaking movements. The movements may be in one or more parts of your body.

Causes of movement disorders include:

  • Genetics
  • Infections
  • Medicines
  • Damage to the brain, spinal cord, or peripheral nerves
  • Metabolic disorders
  • Stroke and vascular diseases
  • Toxins

Treatment varies by disorder. Medicines can cure some disorders. Others get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms and relieve pain.
