D17.79 — Benign lipomatous neoplasm of other sites
D17.79 is a billable, specific ICD-10-CM code for benign lipomatous neoplasm of other sites. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Benign lipomatous neoplasm of peritoneum
- Benign lipomatous neoplasm of retroperitoneum
Other codes that can never be billed with D17.79
These codes carry an Excludes1 note pointing at D17.79. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D17.79 alone.
Risk adjustment
D17.79 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
D17.79 is named in 9 Medicare coverage policies — 9 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
