FH Foundation Guidance: Prior Authorization Criteria for PCSK9 inhibitors for Familial Hypercholesterolemia Treatment in Adults
Diagnostic Criteria for FH
The FH Foundation endorses “The Agenda for Familial Hypercholesterolemia: A Scientific Statement from the AHA”clinical criteria for FH diagnosis.
FH Diagnosis: ICD-10 E78.01
Heterozygous FH: LDL ≥190 at baseline, not due to secondary causes*, and a 1st degree relative similarly affected or with premature Coronary Artery Disease OR a positive genetic test result. Do not require genetic testing.
Homozygous FH: Untreated LDL-C ≥400 mg/dL and 1 or both parents having clinically diagnosed familial hypercholesterolemia, positive genetic testing for an LDL-C-raising (LDL receptor, apoB, or PCSK9) gene defect, or autosomal recessive FH. Do not require genetic testing. If LDL-C ≥560 mg/dL or LDL-C ≥400 mg/dL with aortic valve disease or xanthomata at < 20 years of age, homozygous FH highly likely.
High intensity statin (atorvastatin 40-80mg or rosuvastatin 20-40mg) or maximally tolerated statin or statin intolerant.
Tried 2 statins (one high intensity, one at lowest recommended dose).
Trial optional. 4 weeks.
Treated LDL > 70 with or without ASCVD.
Allow for physician attestation, particularly for pre-treatment LDL-C.
Initial re-authorization after 3 months**, then re-authorization for 3 years.
Abbreviations: FH (familial hypercholesterolemia), PCSK9 (proprotein convertase subtilisin/kexin 9), LDL-C (low density lipoprotein cholesterol), ASCVD (atherosclerotic cardiovascular disease)
*Hypothyroidism, nephrotic syndrome, extreme dietary patterns.
**If patient has 30% or more reduction in LDL-C.
