I67.6 — Nonpyogenic thrombosis of intracranial venous system

Billable / specific codeICD-10-CM

Other codes that can never be billed with I67.6

Risk adjustment

I67.6 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

I67.6 is named in 17 Medicare coverage policies — 17 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
