Code Classification

  • Neoplasms
    (C00–D49)
    • Malignant neoplasms of bone and articular cartilage
      (C40-C41)
      • Malignant neoplasm of bone and articular cartilage of other and unspecified sites
        (C41)

C41.4 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of pelvic bones, sacrum and coccyx. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic bone (periosteum) acetabulum ; Neoplasm, neoplastic bone (periosteum) coccygeal vertebra ; Neoplasm, neoplastic bone (periosteum) coccyx ; Neoplasm, neoplastic bone (periosteum) hip ; Neoplasm, neoplastic bone (periosteum) ilium ; Neoplasm, neoplastic bone (periosteum) innominate ; Neoplasm, neoplastic bone (periosteum) ischium ; etc

Clinical Classification

Clinical Information

  • Coccyx

    the last bone in the vertebral column in tailless primates considered to be a vestigial tail-bone consisting of three to five fused vertebrae.

  • Ischium

    one of three bones that make up the coxal bone of the pelvic girdle. in tetrapods, it is the part of the pelvis that projects backward on the ventral side, and in primates, it bears the weight of the sitting animal.

  • Pubic Bone

    a bone that forms the lower and anterior part of each side of the hip bone.

Table of Neoplasms

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.

Patient Education


Bone Cancer

Cancer that starts in a bone is uncommon. Cancer that has spread to the bone from another part of the body is more common.

There are three types of bone cancer:

  • Osteosarcoma - occurs most often between ages 10 and 19. It is more common in the knee and upper arm.
  • Chondrosarcoma - starts in cartilage, usually after age 40
  • Ewing's sarcoma - occurs most often in children and teens under 19. It is more common in boys than girls.

The most common symptom of bone cancer is pain. Other symptoms vary, depending on the location and size of the cancer. Surgery is often the main treatment for bone cancer. Other treatments may include amputation, chemotherapy, and radiation therapy. Because bone cancer can come back after treatment, regular follow-up visits are important.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
