2025 ICD-10-CM code N63.1

Unspecified lump in the right breast.

Use additional codes to identify any associated symptoms (e.g., pain, nipple discharge) or the results of diagnostic testing. Do not use this code if the lump is identified as a specific condition (e.g., fibroadenoma, cyst). If the lump is in the axillary tail of the breast, use N63.3.

Medical necessity is established by the presence of a palpable lump or abnormality detected during a breast exam, raising concern for a potential underlying condition.Further diagnostic testing, such as imaging or biopsy, is medically necessary to evaluate the lump and determine its nature (benign or malignant).

In simple words: You have a lump in your right breast.Breasts are made up of fatty tissue, connective tissue, and the mammary gland. The mammary gland produces milk during and after pregnancy to feed a baby. You may feel one or more parts of your breast are firmer than usual. These lumps can have many different causes, some harmless, and some may indicate a more severe condition.

Unspecified lump in the right breast.A mass in the mammary gland, either mobile or immobile. Once the mass has reached the size of a small garden pea, it can be detected by palpation. With mammography, a larger number of early breast cancers are being detected since this technique allows detection prior to the point at which the mass can be felt. Breast masses are not always malignant. Benign fibrocystic breast disease is not uncommon. A fine needle biopsy aspiration can distinguish a cystic mass from a solid one.

Example 1: A 45-year-old female patient presents with a palpable lump in her right breast.No other symptoms are present. After examination, the physician documents "Unspecified lump in the right breast" and orders a mammogram., A 60-year-old female patient reports a lump she discovered in her right breast during a self-exam. She has a family history of breast cancer. The physician palpates a mass and documents "Unspecified lump in right breast" prior to ordering further diagnostic testing including mammogram and possible biopsy., During a routine physical examination, a 30-year-old female patient is found to have a small, mobile lump in her right breast.It is not painful, and she had not previously noticed it. The physician notes "Unspecified lump in the right breast" and recommends follow-up imaging.

Detailed clinical documentation of the lump's location (right breast), size, shape, consistency (mobile or fixed), any associated symptoms (pain, nipple discharge), and relevant patient history (family history of breast cancer). Results of any imaging studies (mammogram, ultrasound) or biopsies performed should also be included.

** This code is used when the nature of the lump is unspecified, and further diagnostic evaluation is needed.The final diagnosis may be a benign condition or a malignant tumor. It is crucial to perform a thorough evaluation and document all findings for accurate coding and appropriate patient management.
