Answer: D
N81.1 is the appropriate code because it is used to code for cystocele which is the diagnosis in this patient. In cystocele, female genital prolapse occurs that causes a feeling of heaviness in the pelvis, urine continence, urge to urinate frequently, and disturbed bowel movements.
Option A is not correct because N81.6 is used to specify rectocele, which is not the diagnosis here.
Option B is not correct because N81.5 is used to specify vaginal enterocele which is not the diagnosis here.
Option C is not correct because N81.3 is used to code for complete uterovaginal prolapse which is not the diagnosis here.
