Hint: Abnormal versus insufficient cells mean different diagnosis codes When a patient returns to your office for a repeat Pap smear, you-ve got to weigh your options of E/M and specimen-handling codes, as well as diagnosis codes. Take this challenge to see how you fare and prevent payment from slipping through your fingers. Question 1: When a patient comes in for a second Pap smear, what CPT code(s) should you apply and why? Question 2: Will you receive reimbursement for handling the repeat Pap smear? Why or why not? Question 3: If the patient comes back in for a Pap smear due to abnormal results, what ICD-9 code(s) should you use and why? Question 4: If the patient has a repeat Pap because the lab did not have enough cells in the specimen to interpret the results, what ICD-9 code(s) should you use and why?
