Breast cancer icd 10

In the realm of medical coding, the genesis of comprehending and categorizing breast cancer unfurls through the intricate lexicon of ICD-10. This system, intricately designed for the classification of diseases, unveils the labyrinthine nuances of breast cancer diagnosis.

ICD-10, with its intricate web of diagnostic codes, serves as the linguistic prism through which healthcare professionals decipher the intricate tapestry of breast cancer. It delves deep into the domain of medical nomenclature, elucidating the multifarious manifestations of this ailment.

The advent of breast cancer, as encapsulated within the annals of ICD-10, unveils the enigmatic journey from asymptomatic beginnings to the intricate web of diagnostic criteria. The obscure subtleties of disease progression are unraveled as physicians navigate the convoluted landscape of coding.

Breast cancer icd 10

Within the realm of breast cancer, a myriad of classifications and subcategories exist. Although their symptoms may appear analogous, their repercussions on the body and overall well-being are markedly distinct. The breast cancer ICD-10, as delineated by the World Health Organization, stands as an international statistical classification of diseases and related conditions. In its entirety, the ICD-10 encompasses a staggering array of 14,000 distinctive codes. Furthermore, there exist modified iterations of the ICD-10, boasting an additional compendium of over 70,000 procedure codes (CM). Within the domain of breast cancer, the classifications C50, D05, and Z85 encapsulate the diverse spectrum of malignant neoplasms affecting the breast, afflicting both females and males alike.

The breast cancer ICD-10 CM code C50 is minutely subdivided into its respective subcategories, including C50.911, C50.022, and C50.829, facilitating precise identification of the tumor’s anatomical location within the breast tissue. Among the panoply of breast cancer variants, invasive ductal carcinoma and invasive lobular carcinoma dominate the landscape, both in terms of diagnosis frequency and rapid disease progression, culminating in expedited health complications.

Invasive Ductal Carcinoma

Also recognized as infiltrating ductal carcinoma, this is the predominant variety of breast cancer diagnosed in women, constituting over 70% of total cases. Within this classification, cancer initiates its progression within the milk ducts and extends into the surrounding breast tissue. The breast cancer ICD 10 CM code employed for the identification of invasive ductal carcinoma stands at C50.919.

It is imperative to comprehend that early-stage symptoms of invasive ductal carcinoma are exceedingly rare. Manifestations of this malady typically become discernible during the advanced stages of breast cancer. To ensure timely detection of breast cancer, it is imperative to undergo bi-annual mammograms or other breast cancer diagnostic procedures recommended by your medical practitioner. A self-breast examination can also be conducted to identify any anomalous growths within the breast. Nonetheless, the aforementioned diagnostic methods remain the quintessential standard for detection.

Let us delve into the potential indicators and manifestations that may arise due to this ailment. If you observe any of the following breast alterations, it is advisable to promptly consult your healthcare provider and seek further assessment.

The signs and symptoms of breast cancer icd 10

The indications and manifestations associated with breast cancer, specifically designated by the ICD-10 CM code C50.919, also recognized as invasive ductal carcinoma, encompass the following:

  1. The presence of a solid or pliable lump detectable through self-breast examination or mammography.
  2. Generalized thickening of the skin enveloping the breast, resulting in a coarser, more substantial texture.
  3. Pruritus accompanied by a rash or discernible redness on the breast’s dermal surface.
  4. Enlargement of the afflicted breast.
  5. Uneven skin texture with dimpling, particularly in the vicinity of the nipple.
  6. An unexpected alteration or the experience of discomfort in any region of the breast.
  7. Nipple transformations, such as inversion, swelling, or alterations in the adjacent skin.
  8. Emission from the nipple, which can be malodorous or odorless.
  9. Enlargement of lymph nodes around the collarbone, neck, and underarm.

It is imperative to acknowledge that these symptoms, linked to breast cancer ICD-10 CM code C50.919, may also manifest in various other medical conditions. Hence, consulting with a local healthcare professional is crucial to obtain a definitive diagnosis. Various diagnostic methods, including mammography, breast ultrasound examinations, CT scans, MRIs, and biopsies, are employed to accurately ascertain the specific cancer type.

The choice of treatment for invasive ductal carcinoma is contingent upon the extent of cancer dissemination. Managing patients in advanced stages of this cancer can be quite challenging. The potential treatments encompass:

  1. Mastectomy and Lumpectomy, both surgical procedures employed to independently excise abnormal masses or lumps within the breast.
  2. Lymph node biopsy, performed post-breast cancer diagnosis to determine the most appropriate treatment approach.
  3. Axillary node dissection, conducted when cancer has metastasized to distant bodily regions. The breast cancer ICD-10 CM code C50.919 involves axillary lymph nodes, and this dissection varies based on the extent of lymph node involvement, spanning three distinct levels.
  4. Hormone therapy, recommended for select patients, targeting specific hormones that can precipitate breast cancers like invasive ductal carcinoma.
  5. Radiation therapy or chemotherapy, suitable for patients with widespread cancer dissemination throughout the body.
  6. In severe instances of breast cancer, it may be necessary to remove healthy breast tissue along with cancerous tissues, resulting in alterations in breast shape. Several breast reconstruction procedures are available to restore breast contours.

As advancements in cancer detection and treatment continue to evolve, the prospects of successfully addressing nearly all cancer types become increasingly viable. Invasive ductal carcinoma, exemplified by breast cancer ICD-10 CM code C50.919, indeed represents an aggressive form of cancer. However, diligent monitoring of one’s current health status and adherence to scheduled bi-annual breast screening tests can contribute significantly to early detection and successful treatment.


Vigilance and early detection play pivotal roles in the battle against breast cancer, including the formidable invasive ductal carcinoma (ICD-10 CM code C50.919). With advancing medical techniques and a proactive approach to health, there is hope for successful treatment and recovery. Remember, regular screenings and consultation with healthcare professionals are essential in safeguarding your well-being. Stay proactive, stay informed, and prioritize your health.
