ICD-10 Code D16.12 – Benign neoplasm of short bones of left upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D16.12 – Benign neoplasm of short bones of left upper limb
What it is
This code identifies a noncancerous tumor arising in a short bone of the left upper limb, such as a carpal or metacarpal bone. Use it when the record specifically documents a benign neoplasm in that anatomic site.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include a localized mass, swelling, pain, or incidental imaging evidence of a benign bone lesion in the left hand or wrist region.
When to use this code
Use D16.12 when the provider documents a benign neoplasm confined to a short bone of the left upper limb. This applies to confirmed benign bone tumors in the left carpal or metacarpal area. If the note only says “bone lesion” or the site is unclear, check documentation before coding.
Do not use for
Do not use this code for malignant bone tumors, metastatic disease, or lesions in other bones or limbs. Check documentation if the lesion is uncertain, unspecified, or described only as cystic or inflammatory.
Coding tip
Verify both laterality and bone group: D16.12 requires a benign neoplasm of a short bone on the left side.
