D29.21 is a billable ICD-10 code used to specify a medical diagnosis of benign neoplasm of right testis. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
This code is applicable to male patients only. It is clinically and virtually impossible to use this code on a non-male patient.
The following anatomical sites found in the Table of Neoplasms reference the parent code D29.2 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic testis, testes ; Neoplasm, neoplastic testis, testes descended ; Neoplasm, neoplastic testis, testes ectopic ; Neoplasm, neoplastic testis, testes retained ; Neoplasm, neoplastic testis, testes scrotal ; Neoplasm, neoplastic testis, testes undescended ; Neoplasm, neoplastic testis, testes unspecified whether descended or undescended ; etc
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Benign neoplasm of right testis
- Benign neoplasm of testis
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:

|Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.|
Table of Neoplasms
The parent code D29.2 of the current diagnosis 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.

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.

Testicles, or testes, make male hormones and sperm. They are two egg-shaped organs inside the scrotum, the loose sac of skin behind the penis. It's easy to injure your testicles because they are not protected by bones or muscles. Men and boys should wear athletic supporters when they play sports.
You should examine your testicles monthly and seek medical attention for lumps, redness, pain or other changes. Testicles can get inflamed or infected. They can also develop cancer. Testicular cancer is rare and highly treatable. It usually happens between the ages of 15 and 40.
