Risk adjustment in I80-I89
0 codes in this block map to a CMS-HCC, which means the diagnosis carries a risk-adjustment payment when it is documented and coded. Under-coding here is money left on the table; over-coding here is what audits are for.

- HCC 383 Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle
- HCC 63 Chronic Liver Failure/End-Stage Liver Disorders
What else to watch in I80-I89
- 144 codes are laterality-specific. They come in left and right pairs, and the pair is mutually exclusive on a single site: coding both without a bilateral code is a contradiction a scrubber should catch before the payer does.
- 288 codes are named in Medicare coverage policies. An LCD or NCD lists them as supporting medical necessity, or explicitly as not supporting it. Which applies depends on the MAC for your state.
