E72.3 — Disorders of lysine and hydroxylysine metabolism
E72.3 is a billable, specific ICD-10-CM code for disorders of lysine and hydroxylysine metabolism. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Glutaric aciduria NOS
- Glutaric aciduria (type I)
- Hydroxylysinemia
- Hyperlysinemia
Other codes that can never be billed with E72.3
These codes carry an Excludes1 note pointing at E72.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E72.3 alone.
- E71.313Glutaric aciduria type II
Risk adjustment
E72.3 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.
How E72.3 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to E72.3.
