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.

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.

CCSR Code: NEO073

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.

• Cleft Palate

congenital fissure of the soft and/or hard palate, due to faulty fusion.

• Palatal Obturators

appliances that close a cleft or fissure of the palate.

• Palate

the structure that forms the roof of the mouth. it consists of the anterior hard palate (palate, hard) and the posterior soft palate (palate, soft).

• Palate, Hard

the anteriorly located rigid section of the palate.

• Palate, Soft

a movable fold suspended from the posterior border of the hard palate. the uvula hangs from the middle of the lower border.

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.

ICD-9-CM: 210.4

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.

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form a tumor.

Treatment often involves surgery. Benign tumors usually don't grow back.

Mouth Disorders

Your mouth is one of the most important parts of your body. It has many different functions. It allows you to:

• Take in food and drink
• Breathe in air
• Start digestion, with your teeth chewing the food you eat and your salivary glands releasing saliva to help break down the food
• Speak and sing
• Show emotion, by smiling or pouting

Any problem that affects your mouth can make it hard to eat, drink, or even smile. Some common mouth problems include:

• Cold sores - painful sores on the lips and around the mouth, caused by a virus
• Canker sores - painful sores in the mouth, caused by bacteria or viruses
• Thrush - a yeast infection that causes white patches in your mouth
• Leukoplakia - white patches of excess cell growth on the cheeks, gums or tongue, common in smokers
• Dry mouth - a lack of enough saliva, caused by some medicines and certain diseases
• Gum or tooth problems
• Bad breath

Treatment for mouth disorders varies, depending on the problem. If a mouth problem is caused by some other disease, treating that disease can help. It is also important to keep your mouth clean and healthy by brushing, flossing, and not using tobacco.
