Question:
Would I code a melanocytic nevi of the right shoulder with ICD-10-CM code D48.5?

Answer:
No, you would not use D48.5 which is neoplasm of uncertain behavior. The only time you would report D48.5 is when you have confirmation from a pathology or histology report stating behavior is uncertain or unpredictable.
You should report D22.61 (Melanocytic nevi of right upper limb, including shoulder).
Keep in mind D22.6- and D22.7- require the specific anatomic location of the nevi documented.
