Incision & Drainage of Abscess - CDT Code Guide
Overview
CDT Code D7520 refers to the incision and drainage of an abscess located in the extraoral soft tissue, which involves making an incision through the skin. This procedure is typically performed by oral and maxillofacial surgeons to relieve pain and infection caused by abscesses that form outside the oral cavity. Common scenarios include abscesses resulting from dental infections that have spread beyond the oral cavity, trauma, or other infections. The procedure is crucial for preventing the spread of infection and alleviating discomfort for the patient. Clinically, this procedure is often necessary when antibiotics alone are insufficient to resolve the infection.
When to Use This Code
- When an abscess is present in the extraoral soft tissue and requires drainage.
- In cases where a dental infection has spread beyond the oral cavity.
- When a patient presents with facial swelling and pain due to an abscess.
- In situations where conservative treatments have failed to resolve the infection.
- When imaging confirms the presence of an extraoral abscess.
Documentation Requirements
- Detailed clinical notes describing the location and size of the abscess.
- Pre-operative and post-operative photographs, if applicable.
- A description of the incision and drainage procedure performed.
- Patient consent forms for the surgical procedure.
- Follow-up care instructions provided to the patient.
- Documentation of any complications or additional treatments required.
Billing Considerations
When billing for D7520, it is important to note that this code is specific to extraoral abscesses. Ensure that the procedure is documented thoroughly to justify the use of this code.
