Code Classification

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

D16.22 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of long bones of left lower limb. 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 the parent code D16.2 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic bone (periosteum) femur (any part) ; Neoplasm, neoplastic bone (periosteum) fibula (any part) ; Neoplasm, neoplastic bone (periosteum) knee ; Neoplasm, neoplastic bone (periosteum) leg NEC ; Neoplasm, neoplastic bone (periosteum) limb NEC lower (long bones) ; Neoplasm, neoplastic cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] semilunar (knee) ; Neoplasm, neoplastic femur (any part) ; etc

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Benign neoplasm of bone of left lower limb
  • Benign neoplasm of long bone of left lower limb
  • Bilateral enostosis of femurs
  • Enostosis of femur
  • Enostosis of fibula
  • Enostosis of left fibula

Clinical Classification

Convert D16.22 to ICD-9-CM

  • ICD-9-CM Code: 213.7 - Ben neo long bones leg
    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 D16.2 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.

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

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.
