aetna covering formula-help!!!!

Rosa
Hi! I was wondering if any of you have gone through this situation I am in.
My baby is allergic to milk protein. He has gone through a specialist who put him on special formula (Elecare $45.99 a can) and aetna is refusing to cover for it. They say they will cover once I meet my deductible of $1,500. To me it sounds ridiculous because by then I probably won't even need the formula. My thing is that I have done my research and through the state of TX, which is where we live, the insurance provider is required to cover for the formula. I am just a bit confused to whether they are technically covering for it, since they say they will if I meet my deductible or if they should cover before I even meet it? 
Here is what the state bill reads-
"Texas 

Statute–Tx. Ins. Code § 1377.051Weblink– http://www.statutes.legis.state.tx.us/Docs/IN/htm/IN.1377.htmRequires insurance coverage for amino acid-based elemental formulas for treatment of eosinophilic disordersLanguage of StatuteCoverage for Certain Amino Acid Based Elemental Formulasa) A health benefit plan must provide coverage as provided by this chapter for amino acid‑based elemental formulas, regardless of the formula delivery method, that are used for the diagnosis and treatment of:(1) immunoglobulin E and non‑immunoglobulin E mediated allergies to multiple food proteins;(2) severe food protein‑induced enterocolitis syndrome;

(3) eosinophilic disorders, as evidenced by the results of a biopsy; and

(4) impaired absorption of nutrients caused by disorders affecting the absorptive surface, functional length, and motility of the gastrointestinal tract.

(b) Subject to Subsection (c), the coverage required under Subsection (a) is required if the treating physician has issued a written order stating that the amino acid‑based elemental formula is medically necessary for the treatment of an enrollee who is diagnosed with a disease or disorder listed in Subsection (a). The coverage must include coverage of any medically necessary services associated with the administration of the formula.

(c) A health benefit plan must provide the coverage described by Subsection (a) on a basis no less favorable than the basis on which prescription drugs and other medications and related services are covered by the plan, and to the same extent that the plan provides coverage for drugs that are available only on the orders of a physician."

I am confused and really need some help. Aetna is pretty much okay with me not having enough money to pay for my son's formula, which is his only way of survival. Yet, I make "too much" money to qualify for a government funded program.

Help!!!
