Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

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.

Other specified status

CCSR Code: FAC025

Inpatient Default: X - Not applicable.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

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.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Chairridden
  • Reduced mobility NOS

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • wheelchair dependence Z99.3

Code Edits

The Medicare Code Editor (MCE) detects errors and inconsistencies in ICD-10-CM diagnosis coding that can affect Medicare claim validity. These Medicare code edits help medical coders and billing professionals determine when a diagnosis code is not appropriate as a principal diagnosis, does not meet coverage criteria. Use this list to verify whether a code is valid for Medicare billing and to avoid claim rejections or denials due to diagnosis coding issues.

Unacceptable principal diagnosis

There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal 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
