Hint: You’ll 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.
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.
