I work in a dermatology office and many times we have patients come in for "a spot on the back" (this is for ones that they say are not painful and that have or have not notices changes in) the doctor looks at it and charges and OV but they do not biopsy it therefore not confirming that it's a DN, SCC, BCC etc what would be the correct ICD-9 code to use for diagnosis where the notes are limited or state something like possible nevus possible ISK? etc Any help is greatly appreciated!!!! THANK U
