D7440 is the CDT code for the excision of a malignant tumor — lesion diameter up to 1.25 cm — surgically removing a malignant (cancerous) tumor up to 1.25 cm in diameter. It's used for excising a small malignant tumor (a cancerous mass, which may involve deeper or bony structures, distinguishing it from the 'malignant lesion' codes) — serious cancer surgery, part of comprehensive cancer care with margins, pathology, and typically medical insurance.
What D7440 means
D7440 covers the excision of a malignant tumor — lesion diameter up to 1.25 cm. "D" is dental, "74" is this oral surgery group, and "40" is this small malignant tumor excision. A malignant tumor is a cancerous tumor (mass) — cancer tissue forming a tumor. The CDT distinguishes 'malignant tumor' codes (D7440/D7441) from 'malignant lesion' codes (D7413/D7414/D7415): while both involve cancer, the 'tumor' codes generally refer to a more substantial cancerous tumor that may involve deeper structures (e.g., a tumor of the jaw — involving the bone — versus a more superficial soft-tissue lesion). D7440 is for excising a malignant tumor up to 1.25 cm in diameter (a small malignant tumor). So when a small (up to 1.25 cm) malignant tumor is excised, D7440 reports this.
So it's surgically removing a small (up to 1.25 cm) malignant (cancerous) tumor — serious cancer surgery, potentially involving deeper/bony structures.
A malignant tumor (especially one involving the jaw bone or deeper structures) is a serious cancer requiring comprehensive treatment. Excising it involves removing the tumor with appropriate margins (to remove all the cancer), and the tissue is examined by pathology (confirming the cancer type/grade and margins). Because a malignant tumor may involve bone or deeper structures, the excision can be more involved than a superficial soft-tissue lesion excision (potentially requiring bone removal). The management is comprehensive cancer care — staging, a treatment plan (possibly more extensive surgery, reconstruction, radiation, chemotherapy), evaluation for spread, and ongoing care — managed by a cancer care team (oral/maxillofacial or head-and-neck surgeons, oncologists). D7440 is the small malignant tumor excision; D7441 is the larger one (over 1.25 cm). The most extensive cancer surgery (removing a large portion of the jaw) is radical resection (D7490). Oral cancer care typically involves medical insurance. This is a sensitive topic — anyone facing an oral cancer diagnosis should work closely with their cancer care team.
When it's typically used
D7440 is reported for excising a malignant (cancerous) tumor up to 1.25 cm in diameter — surgically removing a small malignant tumor (a cancerous mass, potentially involving deeper or bony structures) with margins and pathology. It's serious cancer surgery, part of comprehensive cancer care, distinguished from the 'malignant lesion' codes (D7413+) and the larger malignant tumor (D7441).
How much does D7440 cost?
Excision of a small malignant tumor is a significant fee, often roughly 700 to 2,000+ USD for the excision itself depending on region, the structures involved (e.g., bone), and complexity — but oral cancer care is typically much more comprehensive (staging, possibly extensive surgery, reconstruction, and other treatments), with the overall cost far exceeding the excision. The pathology is critical (separate fee). Medical insurance is typically the primary coverage. This is a sensitive topic — work closely with your cancer care team.
Is D7440 covered by insurance?
Typically involves medical insurance (oral cancer care is a medical matter). Documentation of the malignant tumor (the diagnosis, size up to 1.25 cm, the structures involved, the excision with margins) and coordination with the cancer care team apply. The pathology is critical. It's distinguished from the 'malignant lesion' codes (D7413+) and the larger malignant tumor (D7441). Cancer care involves comprehensive coverage considerations; verifying with both medical and the care team is important.
Malignant tumor vs malignant lesion
The 'tumor' and 'lesion' codes are distinct, and understanding this clarifies D7440.
The CDT has separate codes for malignant 'tumors' (D7440/D7441) and malignant 'lesions' (D7413/D7414/D7415) — and understanding the distinction clarifies D7440. Both involve cancer (malignancy), but the codes are distinguished by the nature/extent of the cancerous growth: malignant lesion (D7413-D7415) — generally a more superficial cancerous lesion (e.g., of the soft tissue/mucosa — a cancer of the lining of the mouth), excised from the soft tissue; malignant tumor (D7440/D7441) — generally a more substantial cancerous tumor that may involve deeper structures, including the bone (e.g., a malignant tumor of the jaw — involving the maxilla or mandible), requiring a more involved excision (potentially including bone). So the 'tumor' codes (D7440/D7441) typically refer to a more substantial/deeper cancer than the 'lesion' codes.
This distinction reflects the different surgical considerations: removing a malignant tumor involving bone (D7440/D7441) is more involved than removing a superficial malignant lesion (D7413-D7415) — involving deeper/bony structures and a more extensive procedure. So D7440 (small malignant tumor) is for a small but more substantial/deeper cancer, versus D7413 (small malignant lesion) for a superficial one. The surgeon/cancer team codes based on the nature of the cancer (a superficial lesion vs a more substantial tumor involving deeper structures). Both are serious cancer, managed comprehensively. So D7440 is the small malignant tumor excision (distinct from the lesion codes). The cancer team codes by the cancer's nature. For patients, understanding that the 'tumor' and 'lesion' codes are distinct clarifies D7440. It's for a tumor (more substantial/deeper). The team codes by the nature. Understanding this helps patients see that the CDT distinguishes malignant 'tumor' codes (D7440/D7441) from malignant 'lesion' codes (D7413-D7415) — both involving cancer, but the 'tumor' codes generally referring to a more substantial cancerous tumor that may involve deeper structures including bone (e.g., a malignant tumor of the jaw), requiring a more involved excision, versus the 'lesion' codes for a more superficial cancer (e.g., of the soft tissue) — so D7440 is the small (up to 1.25 cm) malignant tumor excision, distinct from D7413 (the small malignant lesion), with the cancer team coding based on the nature and extent of the cancer.
Excising a malignant tumor
Excising a malignant tumor is serious cancer surgery, and understanding it clarifies the procedure.
Excising a malignant tumor (D7440) is serious cancer surgery — and understanding it clarifies the procedure. The procedure involves removing the cancerous tumor with the goals of complete removal and clear margins, and (since a tumor may involve deeper/bony structures) it can be more involved: excision with margins — removing the tumor along with a margin of surrounding normal tissue (to remove all the cancer, including microscopic extension, and achieve clear margins — critical for cancer); involving deeper structures — for a tumor involving the bone (e.g., the jaw), the excision includes the involved bone (removing the tumor and the affected bone with margins), a more extensive procedure than a soft-tissue excision; critical pathology — examining the removed tissue (confirming the cancer type/grade and the margins); and reconstruction — for a tumor removal involving bone/significant tissue, reconstruction may be needed (restoring the area), as part of the broader treatment. So excising a malignant tumor is an involved cancer surgery.
Given the seriousness and potential bone involvement, this surgery is typically done by an oral/maxillofacial or head-and-neck surgeon, often in a surgical/hospital setting (under general anesthesia for an involved removal). It's part of comprehensive cancer care — staging (determining how advanced the cancer is), evaluation for spread (e.g., to lymph nodes), and the overall treatment plan (which may include additional surgery, radiation, chemotherapy, and reconstruction). So excising a malignant tumor is serious, comprehensive cancer surgery. The cancer care team manages it. For patients, understanding that excising a malignant tumor is serious cancer surgery clarifies the procedure. It's involved cancer surgery. The team manages it. Understanding this helps patients see that excising a malignant tumor (D7440) is serious cancer surgery — removing the cancerous tumor with margins (for complete removal and clear margins), potentially involving deeper/bony structures (e.g., removing the affected jaw bone for a tumor involving it, a more extensive procedure), with critical pathology and possible reconstruction — typically done by an oral/maxillofacial or head-and-neck surgeon in a surgical setting, as part of comprehensive cancer care (staging, evaluation for spread, and a treatment plan that may include additional surgery, radiation, chemotherapy, or reconstruction) managed by the cancer care team.
The malignant tumor and resection codes
The malignant tumor codes relate to other cancer codes, and understanding this clarifies the coding.
The malignant tumor excision codes relate to the other cancer-surgery codes — and understanding this clarifies the coding. The malignant tumor codes: D7440 — excision of malignant tumor, lesion diameter up to 1.25 cm (small — this code); D7441 — excision of malignant tumor, lesion diameter greater than 1.25 cm (larger). These are for excising a malignant tumor (by size). Related cancer-surgery codes: malignant lesion excisions (D7413/D7414/D7415) — for more superficial malignant lesions (by size and complexity), as discussed; and radical resection (D7490) — radical resection of the maxilla or mandible, the most extensive cancer surgery (removing a large portion of the jaw for an extensive cancer). So the cancer-surgery codes span from lesion excisions (more superficial) to tumor excisions (D7440/D7441, more substantial/deeper) to radical resection (D7490, the most extensive).
The coding reflects the extent of the cancer surgery: a superficial malignant lesion → the lesion codes (D7413-D7415); a more substantial malignant tumor (possibly involving bone), excised → the tumor codes (D7440 up to 1.25 cm, D7441 over 1.25 cm); a very extensive cancer requiring radical resection of the jaw → D7490. So the surgeon/cancer team codes based on the extent of the cancer and the surgery. D7440 specifically is the small malignant tumor excision (more involved than a lesion excision, but less than a radical resection). The diagnosis and surgical extent determine the code. So D7440 fits among these cancer-surgery codes. The team codes by the extent. For patients, understanding that the malignant tumor codes relate to the other cancer codes clarifies the coding. D7440 is the small tumor excision. The team codes by the extent. Understanding this helps patients see that the malignant tumor excision codes (D7440 up to 1.25 cm, D7441 over 1.25 cm) fit among the cancer-surgery codes — which span from the more superficial malignant lesion excisions (D7413-D7415), to the more substantial malignant tumor excisions (D7440/D7441, possibly involving bone), to the most extensive radical resection of the jaw (D7490) — so the cancer team codes based on the extent of the cancer and surgery, with D7440 being the small malignant tumor excision (more involved than a lesion excision but less than a radical resection).
Comprehensive care for a malignant tumor
A malignant tumor requires comprehensive care, and understanding this is important for anyone facing it.
A malignant tumor (the subject of D7440) requires comprehensive, specialist cancer care — and understanding this is important. As serious cancer (potentially involving the jaw/deeper structures), it's managed by a team and a comprehensive approach: the specialist team — oral/maxillofacial or head-and-neck surgeons, medical and radiation oncologists, pathologists, reconstructive surgeons, and others (rehabilitation, support); diagnosis and staging — establishing the diagnosis (biopsy/pathology) and staging the cancer (its extent and spread), which guides treatment; comprehensive treatment — a plan based on the cancer's type and stage, which may include the surgical excision (D7440 for a small tumor), reconstruction (restoring the area, especially if bone was removed), radiation therapy, and/or chemotherapy; and ongoing care — follow-up (monitoring for recurrence) and rehabilitation (restoring function, e.g., after jaw surgery). So a malignant tumor needs comprehensive, coordinated care.
The excision (D7440) is one component of this broader treatment. Early detection and treatment improve outcomes. For anyone facing such a diagnosis, the essential step is to work closely with the cancer care team — they provide the individualized diagnosis, staging, treatment plan, surgery, reconstruction, and care. This is a serious, sensitive medical situation where professional, individualized guidance is essential; this page provides general context (about the D7440 code), not a substitute for that care. So a malignant tumor needs comprehensive care, guided by the cancer care team. For patients, understanding that a malignant tumor requires comprehensive care is important for anyone facing it. It needs comprehensive specialist care. The team guides it. Understanding this helps patients see that a malignant tumor (D7440) requires comprehensive, specialist cancer care — a team (surgeons, oncologists, pathologists, reconstructive surgeons), diagnosis and staging (guiding treatment), and a treatment plan that may include the surgical excision, reconstruction (especially if bone was removed), radiation, and/or chemotherapy, plus ongoing follow-up and rehabilitation — with the excision being one component, so anyone facing such a diagnosis should work closely with their cancer care team for personalized care (this general information being provided for context, not as a substitute for professional medical guidance).
Frequently asked questions
- What is the D7440 dental code?
- It's the excision of a malignant tumor — lesion diameter up to 1.25 cm — surgically removing a small malignant (cancerous) tumor (a cancerous mass, which may involve deeper or bony structures) with margins and pathology. It's serious cancer surgery, part of comprehensive cancer care, distinct from the 'malignant lesion' codes (D7413+).
- How is a malignant 'tumor' different from a malignant 'lesion'?
- Both involve cancer, but the 'tumor' codes (D7440/D7441) generally refer to a more substantial cancerous tumor that may involve deeper structures including bone (e.g., a malignant tumor of the jaw), requiring a more involved excision — versus the 'lesion' codes (D7413-D7415) for a more superficial cancer (e.g., of the soft tissue).
- What does the procedure involve?
- Removing the cancerous tumor with margins (for complete removal and clear margins), potentially involving deeper/bony structures (e.g., removing affected jaw bone), with critical pathology and possible reconstruction. It's typically done by an oral/maxillofacial or head-and-neck surgeon in a surgical setting, as part of comprehensive cancer care.
- Who manages the treatment?
- A team of specialists — oral/maxillofacial or head-and-neck surgeons, medical and radiation oncologists, pathologists, reconstructive surgeons, and others — providing comprehensive, individualized treatment based on the cancer's type and stage. Anyone facing such a diagnosis should work closely with their cancer care team.
- How much does it cost, and what insurance applies?
- The excision itself may be roughly 700 to 2,000+ USD, but oral cancer care is typically much more comprehensive (staging, possibly extensive surgery, reconstruction, and other treatments), with the overall cost far exceeding the excision. Medical insurance is typically the primary coverage. Work with your care team and medical insurer.
- How does it relate to the other cancer codes?
- The malignant tumor codes are D7440 (up to 1.25 cm — this code) and D7441 (over 1.25 cm). They relate to the more superficial malignant lesion excisions (D7413-D7415) and the most extensive radical resection of the jaw (D7490). The cancer team codes based on the extent of the cancer and surgery.
