Code Classification

  • Neoplasms
    (C00–D49)
    • Benign neoplasms, except benign neuroendocrine tumors
      (D10-D36)
      • Benign neoplasm of bone and articular cartilage
        (D16)

D16.9 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of bone and articular cartilage, unspecified. 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) ; Neoplasm, neoplastic bone (periosteum) cartilage NEC ; Neoplasm, neoplastic bone (periosteum) cuneiform ; Neoplasm, neoplastic bone (periosteum) limb NEC ; Neoplasm, neoplastic cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] ; Neoplasm, neoplastic joint NEC [See Also: Neoplasm, bone] ; Neoplasm, neoplastic skeleton, skeletal NEC ; etc

Unspecified diagnosis codes like D16.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • Chondromatosis

    multiple formation of chondromas. (dorland, 27th ed)
  • Chondromatosis, Synovial

    rare, benign, chronic, progressive metaplasia in which cartilage is formed in the synovial membranes of joints, tendon sheaths, or bursae. some of the metaplastic foci can become detached producing loose bodies. when the loose bodies undergo secondary calcification, the condition is called synovial osteochondromatosis.
  • Exostoses, Multiple Hereditary

    hereditary disorder transmitted by an autosomal dominant gene and characterized by multiple exostoses (multiple osteochondromas) near the ends of long bones. the genetic abnormality results in a defect in the osteoclastic activity at the metaphyseal ends of the bone during the remodeling process in childhood or early adolescence. the metaphyses develop benign, bony outgrowths often capped by cartilage. a small number undergo neoplastic transformation.
  • Osteochondroma

    a cartilage-capped benign tumor that often appears as a stalk on the surface of bone. it is probably a developmental malformation rather than a true neoplasm and is usually found in the metaphysis of the distal femur, proximal tibia, or proximal humerus. osteochondroma is the most common of benign bone tumors.
  • Osteochondromatosis

    a condition marked by the presence of multiple osteochondromas. (dorland, 27th ed)

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


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.

Bone Diseases

Your bones help you move, give you shape and support your body. They are living tissues that rebuild constantly throughout your life. During childhood and your teens, your body adds new bone faster than it removes old bone. After about age 20, you can lose bone faster than you make bone. To have strong bones when you are young, and to prevent bone loss when you are older, you need to get enough calcium, vitamin D, and exercise. You should also avoid smoking and drinking too much alcohol.

Bone diseases can make bones easy to break. Different kinds of bone problems include:

  • Low bone density and osteoporosis, which make your bones weak and more likely to break
  • Osteogenesis imperfecta makes your bones brittle
  • Paget's disease of bone makes them weak
  • Bones can also develop cancer and infections
  • Other bone diseases, which are caused by poor nutrition, genetics, or problems with the rate of bone growth or rebuilding

Cartilage Disorders

Cartilage is the tough but flexible tissue that covers the ends of your bones at a joint. It also gives shape and support to other parts of your body, such as your ears, nose and windpipe. Healthy cartilage helps you move by allowing your bones to glide over each other. It also protects bones by preventing them from rubbing against each other.

Injured, inflamed, or damaged cartilage can cause symptoms such as pain and limited movement. It can also lead to joint damage and deformity. Causes of cartilage problems include :

  • Tears and injuries, such as sports injuries
  • Genetic factors
  • Other disorders, such as some types of arthritis

Osteoarthritis results from breakdown of cartilage.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
