D12.9 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of anus and anal canal. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2025 through September 30, 2026.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic anorectum, anorectal (junction) ; Neoplasm, neoplastic anus, anal ; Neoplasm, neoplastic anus, anal canal ; Neoplasm, neoplastic anus, anal cloacogenic zone ; Neoplasm, neoplastic anus, anal sphincter ; Neoplasm, neoplastic canal ; Neoplasm, neoplastic canal anal ; etc

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.

• Anorectal tubulovillous adenoma
• Benign neoplasm of anal canal
• Benign neoplasm of anal canal
• Benign neoplasm of anus
• Benign neoplasm of anus
• Benign neoplasm of rectum
• Benign neoplasm of rectum and anal canal

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.

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: 211.4

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.

Anal Disorders

What is the anus?

Your anus is the opening at the end of your large intestine. It is where stool (poop) leaves your body.

What are anal disorders?

Problems with the anus are common. They include:

• Hemorrhoids
• Abscesses
• Fissures, small cracks or tears in the lining of your anus
• Anorectal fistula, an abnormal tunnel from your anus or rectum to the skin surface
• Anal itching (pruritus ani)
• Cancer

What are the symptoms of anal disorders?

Your symptoms will depend on which disorder you have. But some of the more common symptoms may include:

• Bleeding
• Discharge
• Itching
• Pain
• Swelling

How are anal disorders diagnosed?

To make a diagnosis, your health care provider will ask about your symptoms and medical history. Depending upon your symptoms, your provider may:

• Check the skin around your anus for anything that looks abnormal.
• Perform a digital rectal exam (DRE). For this exam, your provider inserts a lubricated, gloved finger into the lower part of your rectum to feel for lumps or anything unusual.
• Order tests, such as an anoscopy.

You may be embarrassed to talk about your anal troubles. But it's important to let your provider know about your symptoms, especially if you have pain or bleeding. The more details you can give about your problem, the better your provider can help you.

How are anal disorders treated?

Treatments vary, depending on the condition you have.

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.
