Thanks!
I did a reverse Google lookup on the code you provided and see this
http://bioportal.bioontology.org/ontologies/CPT?p=classes&conceptid=17380, among others.
The code is:
Surgery | Surgical Procedures on the Integumentary System | Other Procedures on the Integumentary System | Electrolysis epilation
I had to look up the word Integumentary System. In laywoman's term, the translation is "skin". That means that 17380 means "electrolysis on the skin". Surgery, well, spraying liquid nitrogen on the skin is a surgery. By this definition, I can submit a 17380 for electrolysis on hair on my back, thighs, face, or anywhere else.
There is nothing in the 17380 CPT code that says "GRS".
Since insurance companies do not pay for electrolysis as a general rule, but do pay for electrolysis with respect to GRS, what will tell the insurance company, Blue Shield of California in this case, that 17380 is for GRS? Since my physician wants only a single code and the form presumably does not have a space to write explanations, what keys the insurance company into GRS?
Is the CPT code used possibly with an ICD code 302.85 (gender dysphoria), although even there that does not say "genital electrolysis in preparation for gender reassignment surgery in M2F individuals".
