Melanoma in situ of other part of trunk
ICD10CM code
Name of the Condition
- Melanoma in situ of other part of trunk
- Also known as “Stage 0 melanoma” or “non-invasive melanoma.”
Summary
Melanoma in situ of the trunk refers to an early, non-invasive stage of melanoma skin cancer located on the trunk of the body. At this stage, abnormal melanocytes (the cells that produce pigment) are confined to the outermost skin layer (epidermis) and have not invaded deeper layers.
Causes
- Genetic mutations affecting melanocyte behavior.
- Prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds.
Risk Factors
- Fair skin, light hair, and eye color.
- History of excessive sun exposure or sunburns.
- Family history of melanoma or other skin cancers.
- Presence of multiple or atypical moles.
Symptoms
- Appearance of a new or unusual dark spot or mole on the skin.
- Changes in size, shape, or color of existing moles.
- Sometimes, the area may be itchy or tender.
Diagnosis
- Skin Examination: Initial visual inspection by a dermatologist.
- Biopsy: Removal and microscopic examination of suspicious skin tissue to confirm melanoma in situ.
Treatment Options
Surgical Excision: Removal of the melanoma along with some surrounding normal skin.
- Ensures complete removal to prevent progression to invasive melanoma.
- Topical Treatments: In specific cases, creams like imiquimod may be used, though surgery is preferred.
- Photodynamic Therapy: Occasionally used, involving a photosensitizing agent and light to destroy cancer cells.
Prognosis and Follow-Up
- Prognosis: Excellent when treated early, as it is non-invasive at this stage.
- Follow-Up: Regular skin checks to monitor for recurrence or new melanomas.
Complications
- Progression to invasive melanoma if untreated.
- Potential for local recurrence even after treatment.
Lifestyle & Prevention
- Sun Protection: Use sunscreen, wear protective clothing, and avoid peak sun hours.
- Avoid Tanning Beds.
- Regular Skin Checks: Self-examinations and professional evaluations.
When to Seek Professional Help
- Changes in skin appearance, such as a new growth or changes in an existing mole.
- Any lesion that bleeds, itches, or does not heal properly.

Tips for Medical Coders
- Ensure precise documentation of the lesion's location on the trunk for accurate coding.
- Avoid coding errors by confirming the diagnosis of "in situ" and not confusing it with invasive melanoma.
