Melanoma in situ of right lower limb, including hip
ICD10CM code
Name of the Condition
- Melanoma in situ of right lower limb, including hip
- Medical term: Melanoma in situ (MIS)
- ICD-10 Code: D03.71
Summary
Melanoma in situ is a very early form of skin cancer where the malignant cells are confined to the outermost layer of the skin, known as the epidermis. When located on the right lower limb, including the hip, it indicates the specific area affected by these precancerous changes.
Causes
Melanoma in situ is primarily caused by damage to skin cells from ultraviolet (UV) radiation, typically from sun exposure or tanning beds. Genetic predisposition and a history of sunburns also contribute to its development.
Risk Factors
- Excessive exposure to UV radiation
- Having fair skin, light hair, and eye color
- A large number of moles or atypical moles
- Family history of melanoma
- Weakened immune system
Symptoms
- A new or existing mole that changes in size, shape, or color
- A mole that becomes itchy, red, or swollen
- Asymmetry in the shape of the mole
- Irregular borders or multiple colors in a mole
Diagnosis
- Dermatological examination
- Dermoscopy to view moles more clearly
- Skin biopsy to examine the tissue for cancerous cells
Treatment Options
- Surgical excision: The primary treatment involves the complete removal of the affected skin area.
- Cryotherapy: Using extreme cold to destroy the tumor cells, though less common for treating MIS.
- Topical therapies: Such as imiquimod in selected cases.
These treatments aim to remove the melanoma cells before they penetrate deeper layers of the skin and spread.
Prognosis and Follow-Up
With early detection and proper treatment, the prognosis for melanoma in situ is excellent, with a low risk of recurrence. Regular skin checks and monitoring by a dermatologist are crucial to identify any new changes early.
Complications
If left untreated, melanoma in situ can progress to invasive melanoma, which can spread to other parts of the body and become life-threatening.
Lifestyle & Prevention
- Regular use of sunscreen with SPF 30 or higher
- Wearing protective clothing and hats when outdoors
- Avoiding tanning beds
- Routine self-examination of the skin for any new moles or changes
When to Seek Professional Help
Seek medical attention if you notice any new or changing moles, particularly if they exhibit the symptoms listed under the "Symptoms" section.

Tips for Medical Coders
- Ensure that the code D03.71 aligns with the location specified as the right lower limb, including the hip.
- Verify that the diagnosis is precisely documented as "in situ" to avoid confusion with invasive melanoma codes.
- Be meticulous with anatomical site specification to prevent coding errors related to laterality.
