CPT code 20931 refers to a specific medical procedure where a piece of bone from a donor is used to help with spinal surgery.
Procedure Explanation:
This procedure involves the use of a donated bone piece—called an allograft—to aid in spine surgery. It’s important to know that this procedure is not the main surgery itself but is often added to support or enhance spinal surgeries. The term “structural” means that the bone piece serves as a sturdy support in the spinal area during surgery. Usually, this is not used by itself but in addition to the main surgical procedure for improving spinal stability or correcting issues.
Common Names:
- Spinal Allograft
- Bone Graft for Spine
- Structural Allograft
Relative Value Units (RVU):
The RVUs associated with this code are 1.81.
How This Procedure Appears:
- Operating Room Schedule Name: Spinal Bone Grafting
- Surgical Consent Form Name: Donor Bone Graft for Spine Support
Typical Patients and Diagnoses:
This procedure is most commonly used for patients with spinal problems that may require added bone support for conditions like degenerative disc disease or scoliosis. For example, someone who has a slipped disc or curvature of the spine may need this procedure as part of their surgery to help in stabilizing the spinal column.
Associated ICD-10 Codes:
- M51.26: This code refers to a condition affecting the lumbar part of the spine where discs are deteriorating, often causing back pain.
- M41.9: This indicates scoliosis, a condition where the spine curves sideways, affecting posture and sometimes mobility.
- M48.06: This represents a spinal collapse or fusion issue, frequently seen in the middle of the spine due to conditions like arthritis.
Summary
In summary, code 20931 describes the use of a donor bone piece in spinal surgeries to provide structural support. Typical ICD-10 codes associated with 20931 include M51.26 (Lumbar disc degeneration) and M41.9 (Scoliosis).
