The use of alpha 1 antitrypsin inhibitors (Aralast, Prolastin, and Zemira) is an important part of the treatment of emphysema in selected circumstances. It is covered, but subject to preauthorization in accordance with medical criteria.


Medical Statement

Alpha 1-antitrypsin inhibitor therapy (e.g., Prolastin, Aralast, and Zemira) is considered medically necessary for selected members with emphysema due to alpha 1-antitrypsin deficiency when all of the following criteria are met:

  1. Member is a non-smoker or an ex-smoker (at least 6 months) (Z87.891); and
  2. Member has PiZZ, PiZ (null) or Pi (null, null) phenotype (homozygous) alpha 1-antitrypsin deficiency (E88.01) or other phenotypes associated with serum alpha 1-antitrypsin concentrations of less than 80 mg per deciliter (mg/dL). (Alpha1-antitrypsin inhibitor is considered not medically necessary for use in individuals with the PiMZ or PiMS phenotypes of alpha 1-antitrypsin deficiency because these individuals appear to be at small risk of developing pan acinar emphysema); and
  3. Member has a low serum concentration of alpha 1-antitrypsin (AAT) less than 80 mg/dL or less than 11 uM/L or less than 0.8 g/L (35% of normal); and
  4. Member has progressive pan acinar emphysema (J43.1) with a documented rate of decline in forced expiratory volume in 1 second (FEV1) of greater than 50cc per year.

Repeat doses of alpha 1-antitrypsin inhibitor therapy are considered medically necessary for members who met the requirements for alpha 1-antitrypsin inhibitor at therapy initiation and who demonstrate a substantial reduction in rate of deterioration of lung function.

Codes Used In This BI:

J0256             Inj: alpha 1-proteinase inhibitor – human, 10 mg (Prolastin, Zemira, Aralast)

S9346            Home infusion: alpha 1-proteinase inhibitor (e.g. Prolastin)


Limits

Because pan acinar emphysema does not develop in some individuals who have alpha 1-antitrypsin deficiency, replacement therapy with alpha 1-antitrypsin inhibitor is of no proven value in affected individuals without clinical evidence of emphysema and is therefore considered experimental and investigational for these individuals.

If the patient starts or resumes smoking, this benefit will end.
