2022 ICD-10-CM Code D12.9
Benign neoplasm of anus and anal canal
Code Classification
D12.9 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of anus and anal canal. The code D12.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code D12.9 might also be used to specify conditions or terms like 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 and anal canal, etc.
The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: anorectum, anorectal (junction) ; anus, anal ; anus, anal canal ; anus, anal cloacogenic zone ; anus, anal sphincter ; canal ; canal anal ; etc
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code D12.9:
Inclusion Terms
Inclusion TermsThese 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.
- Benign neoplasm of anus NOS
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- 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 and anal canal
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code D12.9 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 393 | OTHER DIGESTIVE SYSTEM DIAGNOSES WITH MCC | 06 | 1.6536 |
| 394 | OTHER DIGESTIVE SYSTEM DIAGNOSES WITH CC | 06 | 0.9386 |
| 395 | OTHER DIGESTIVE SYSTEM DIAGNOSES WITHOUT CC/MCC | 06 | 0.6497 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert D12.9 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D12.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Table of Neoplasms
The code D12.9 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.

Information for Patients
Anal Disorders
The anus is the opening of the rectum through which stool passes out of your body. Problems with the anus are common. They include hemorrhoids, abscesses, fissures (cracks), and cancer.
You may be embarrassed to talk about your anal troubles. But it is important to let your doctor know, especially if you have pain or bleeding. The more details you can give about your problem, the better your doctor will be able to help you. Treatments vary depending on the particular problem.

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