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.

Walking Problems
What are walking problems?
If you are like most people, you walk thousands of steps each day. You walk to do your daily activities, get around, and exercise. It's something that you usually don't think about. But for those people who have a problem with walking, daily life can be more difficult.
Walking problems may cause you to:
- Walk with your head and neck bent over
- Drag, drop, or shuffle your feet
- Have irregular, jerky movements when walking
- Take smaller steps
- Waddle
- Walk more slowly or stiffly
What causes walking problems?
The pattern of how you walk is called your gait. Many different diseases and conditions can affect your gait and lead to problems with walking. They include:
- Abnormal development of the muscles or bones of your legs or feet
- Arthritis of the hips, knees, ankles, or feet
- Cerebellar disorders, which are disorders of the area of the brain that controls coordination and balance
- Foot problems, including corns and calluses, sores, and warts
- Infections
- Injuries, such as fractures (broken bones), sprains, and tendinitis
- Movement disorders, such as Parkinson's disease
- Neurologic diseases, including multiple sclerosis and peripheral nerve disorders
- Vision problems
How is the cause of a walking problem diagnosed?
To make a diagnosis, your health care provider will ask about your medical history and do a physical exam. This will include checking your bones and muscles and doing a neurological exam. In some cases, you may have other tests, such as lab or imaging tests.
What are the treatments for walking problems?
Treatment of walking problems depends on the cause. If the cause is a medical condition, treating that condition often improves your walking. Some common types of treatments for walking problems may include:
- Medicines
- Mobility aids such as walkers and canes
- Physical therapy
- Special shoes, insoles, splints, or braces
- Surgery

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.
