Benign neoplasm of bone and articular cartilage (D16)
ICD-10 code D16 covers benign neoplasms (non-cancerous tumors) originating in bone and articular cartilage. These codes specify the location of benign bone tumors in various parts of the body, such as upper and lower limbs, skull and face, vertebral column, ribs, pelvis, and other skeletal regions.
The detailed subcodes like D16.0 to D16.9 help precisely classify benign bone tumors by their location and laterality. For example, D16.00 relates to unspecified benign neoplasms of the scapula and long bones of the upper limb, with common synonyms including osteoid osteoma and osteochondroma. Similarly, D16.4 identifies benign neoplasms of skull and facial bones, incorporating terms like osteoma and fibromyxoma of maxilla. These codes also recognize specific benign tumor types linked to bones such as enchondroma, chondroma, and ameloblastoma. Utilizing this section ensures accurate coding of benign bone tumors, supporting targeted clinical documentation and care management for conditions like bone islands, osteoid osteomas, and benign cartilaginous growths commonly referenced in clinical practice and imaging findings.

Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- benign neoplasm of connective tissue of ear D21.0
- benign neoplasm of connective tissue of eyelid D21.0
- benign neoplasm of connective tissue of larynx D14.1
- benign neoplasm of connective tissue of nose D14.0
- benign neoplasm of synovia D21
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Cementoma
An odontogenic fibroma in which cells have developed into cementoblasts and which consists largely of cementum.
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.
Clavicle
A bone on the ventral side of the shoulder girdle, which in humans is commonly called the collar bone.
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.
Costal Cartilage
Bars of HYALINE CARTILAGE extending from the anterior ends of the upper RIBS. They attach to the STERNUM directly or indirectly by connecting to upper costal cartilage that attaches to the STERNUM. Costal cartilages extend the ribs anteriorly and contribute to the enhanced elasticity of the THORACIC WALL.
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.
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.
Mandible
The largest and strongest bone of the FACE constituting the lower jaw. It supports the lower teeth.
Nucleus Pulposus
Fibrocartilage inner core of the intervertebral disc. Prolapsed or bulged nucleus pulposus leads to INTERVERTEBRAL DISC DISPLACEMENT while proliferation of cells in the nucleus pulposus is associated with INTERVERTEBRAL DISC DEGENERATION.
Osteoblastoma
A benign, painful, tumor of bone characterized by the formation of osteoid tissue, primitive bone and calcified tissue. It occurs frequently in the spine of young persons. (From Dorland, 27th ed; Stedman, 25th ed)
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)
Osteoma
A benign tumor composed of bone tissue or a hard tumor of bonelike structure developing on a bone (homoplastic osteoma) or on other structures (heteroplastic osteoma). (From Dorland, 27th ed)
Osteoma, Osteoid
A benign osteoblastic tumor with central vascularized nidus surrounded by normal reactive bone. It occurs especially in second decade of life most commonly in the femoral neck but can occur in any bone and any site within a bone.
Osteomalacia
Disorder caused by an interruption of the mineralization of organic bone matrix leading to bone softening, bone pain, and weakness. It is the adult form of rickets resulting from disruption of VITAMIN D; PHOSPHORUS; or CALCIUM homeostasis.
Pubic Bone
A bone that forms the lower and anterior part of each side of the hip bone.
Sternum
A long, narrow, and flat bone commonly known as BREASTBONE occurring in the midsection of the anterior thoracic segment or chest region, which stabilizes the rib cage and serves as the point of origin for several muscles that move the arms, head, and neck.
