Melanoma down to the Fascia

I have a few questions - I have a patient who had a 1.1 centimeters excision of melanoma insitu with wide margins up the upper arm
Here is the majority of the OP report

Patient taken to OP room , General anesthesia was done . An Elliptical incision was made and carried DOWN TO THE FASCIA , the lesion was then removed and a stitch placed at the 12 oclock for orientation purposes. we then widely undermined the tissues using electrocautery so that we could effect a primary closure .

Path came back - Melanoma in Situ

Path says the following : skin biopsy , skin left arm, superficial spreading melanoma in situ : received in formalin pink tan skin with underlying fatty tissue

So here is my question : Since the excision went down to the fascia, would this be a code that codes to the integumentary system or will this get coded to the musculoskeletal system. I need solid proof .
I thought perhaps it would code to 24075 ,however, I was told since melanoma is a skin lesion originally it would only be coded to the 11602 .
I guess I am looking for SOLID proof that states, melanomas can only be coded to the 11600 series .

I thought the musculoskeletal codes were used for patients where the excision went down to subcutaneous regardless of if it was cancer or not cancer.

Any advice or help is appreciated.

24075 Excision, tumor, soft tissue of upper arm or elbow area, subcutaneous; less than 3 cm
24071 Excision, tumor, soft tissue of upper arm or elbow area, subcutaneous; 3 cm or greater
24076 Excision, tumor, soft tissue of upper arm or elbow area, subfascial (e.g., intramuscular);
less than 5 cm
24073 Excision, tumor, soft tissue of upper arm or elbow area, subfascial (e.g., intramuscular); 5
cm or greater

Layers of skin...

dermis
epidermis
subcutaenous fat
fascia
muscle (i.e.sub-fascia)

HOWEVER, just because you cut that far doesn't mean you code that far. You should code based on where it was located.

According to the AMA, you should use the soft tissue excision codes when the tumor is located in the subcutaneous, fascial or muscular location.

The path report shows it was SUPERFICIAL, or on the surface.

Use the 11602 series

The 2407X series codes are usually for cysts/lipomas located further down.

Thank you -
I will keep all this in mind the next time I have one similar :)
