we had one female 14 years old patients come to the clinic with lump in breast. Clinician diagnosed Fibrocystic breast. There is ICD 9 code is 610.1 but when i am looking ICD 10 code for that, than N60.19. But this code id only used for adult population. And here my patients is 14 years old, my system doesn't allow me to use that code. So, Could you please help me , what should I do? Is there any other code available for Pediatrics age for Fibrocystic Breast?
