Pathology/Lab Coding Alert

Apply the same PIN rules even when the codes change.

If you don't have any trouble using the ICD-9 neoplasm table, you shouldn't have a hard time transitioning to ICD-10 neoplasm codes starting Oct. 1, 2013.

For example, here's how the two code set options for malignant prostate cancer coding compare:

ICD-9: Under ICD-9, your prostate neoplasm options include:

• Primary: 185, Malignant neoplasm of prostate
• Secondary: 198.82, Secondary malignant neoplasm of genital organs
• Ca in Situ: 233.4, Carcinoma in situ of prostate.

If you report prostatic intraepithelial neoplasia (PIN), you should use 233.4 for PIN III. But you should use 602.3 (Dysplasia of prostate) for PIN I or PIN II.

ICD-10: Your ICD-10 options offer up familiar terms:

• Primary: C61, Malignant neoplasm of prostate
• Secondary: C79.82, Secondary malignant neoplasm of genital organs
• Ca in Situ: D07.5, Carcinoma in situ of prostate.

If you report PIN III, you should use D07.5. For PIN I or PIN II, you should use N42.3 (Dysplasia of prostate) instead.

Remember: When ICD-10 goes into effect on Oct. 1, 2013, you should apply the code set and official guidelines in effect for the date of service reported. Learn more at www.cms.gov/ICD10/ and www.cdc.gov/nchs/icd/icd10cm.htm#10update
