Q82.0 — Hereditary lymphedema
Q82.0 is a billable, specific ICD-10-CM code for hereditary lymphedema. It is valid for submission on a claim.
Other codes that can never be billed with Q82.0
These codes carry an Excludes1 note pointing at Q82.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q82.0 alone.
Risk adjustment
Q82.0 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
Q82.0 is named in 10 Medicare coverage policies — 9 listing it as supporting medical necessity, and 1 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
