Good news: ASC-US, ASC-H, LGSIL, and HGSIL will have one-to-one matches.
When a patient's cervical Pap smear returns abnormal results, you should report 795.0x (Abnormal Papanicolaou smear of cervix and cervical HPV). This code series requires a fifth digit, and if you don't include it, this "could be a reason for a denial," says Peggy Stilley, CPC, COBGC, ACS-OB, director of auditing services at the American Academy of Professional Coders.
Here how ICD-9 defines this series:
For example, a 35-year-old woman with multiple sexual partners presents for an annual exam. She has not had a Pap smear in four years. The Pap results return ASC-US, and the physician asks her to come back in three months for a repeat Pap to follow any abnormal cell progress. When the patient returns, you should code the appropriate E/M office visit with 795.01 because the Pap is repeated due to abnormal cells.
ICD-10: When Oct. 1 2013 turns around, you'll shift to R87.61x (Abnormal cytological findings in specimens from cervix uteri) for most of the current 795.0x codes. In this case, you'll need to add a sixth digit.
You'll break out this series as follows:
So, looking back at the previous example, if you're submitting a claim after Oct. 1, 2013, you would report R87.610 instead.
Here's how the correlations match up:
Note: Codes 795.05 and 795.09 do not stay within the R87.61x range. Instead, you'l report R87.810 (Cervical high risk human papillomavirus [HPV] DNA test positive) for high risk HPV and R87.820 (Cervical low risk human papillomavirus [HPV] DNA test positive) for low risk HPV.
