Clinical Classification
Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.
They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.
Nervous system signs and symptoms
CCSR Code: SYM010
Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.
Clinical Information
Dysmetria
lack of coordination of movement necessary to execute a smooth action; often the person over reaches or under reaches. this condition is sometimes symptomatic of a cerebellar cognitive dysfunction.Asterixis
a tremor of the wrist that is observed when the wrist is extended.Dysgraphia
a neurological disorder characterized by impairment of handwriting ability that may be associated with other learning disabilities in children or traumatic damage to the parietal lobe in adults.

Convert R27.8 to ICD-9-CM
Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.
Lack of coordination
ICD-9-CM: 781.3
Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.
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 a disorder that slowly gets worse over time. It causes tremors, slowness of movement, and trouble walking.
- Tourette syndrome, a condition that 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.

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.
