Keep chemo-pill copays in line with infusion copays

Some Texas plans must keep your share of chemo-pill costs no worse than your share for infused chemo.

What it is

Some Texas plans must keep your share of chemo-pill costs no worse than your share for infused chemo.

Chemo pills can bring pharmacy charges that look different from an infusion bill. Texas’s parity rule compares those costs for plans it covers. It can matter during maintenance with medicines such as 6-MP and methotrexate.

Who this can help
  • The Texas law applies to the insured plans listed in Insurance Code 1369.202. Exchange qualified health plans, self-funded employer plans, Medicaid and CHIP are excluded.
  • The statutory list does not name ERS, TRS-Care, TRS-ActiveCare or UT/A&M plans. Their administrators can explain their own drug-cost policies.
What you get
  • Your share for covered chemo pills cannot be less favorable than the infusion benefit.
  • A correction or refund when the plan charged more than the rule allows.
What the rules cover
  • Texas requires oral-versus-intravenous anticancer cost-sharing parity, without a separate dollar ceiling.
  • Formulary and prior-authorization rules still apply. The oncology team confirms that the medicine qualifies as an oral anticancer drug.
If you decide to apply
  1. Ask HR whether an insurer pays your plan’s claims and whether the policy is issued in Texas.
  2. Give the pharmacy team your drug receipt, benefit booklet and infusion explanation of benefits.
  3. Ask the pharmacy team to help you request, in writing, how the plan compared the pill charge with its infusion benefit.

What happens next
  • The plan gives its written answer through its grievance process. TDI can review a complaint about a covered plan.
  • A refusal should identify the plan exclusion or benefit calculation, so the pharmacy team can check it.
Good to know

Parity does not mean free medicine. The plan’s infusion costs may still be substantial.

Other details
  • TRS-ActiveCare and ERS have their own appeal routes. A change to medical prior authorization does not settle their pharmacy benefits.

Ask your social worker

“If our chemo-pill bill looks high, can you help compare it with the infusion benefit and check whether Texas’s cost rule applies?”

Why I’m asking: I want to understand the pharmacy charge before treating it as the amount we owe.

Who does what

The three parts, side by side. The agency decides; nobody on this page does.

You

Ask HR whether the plan is fully insured. When a chemo-pill copay looks high, ask the plan in writing to apply the parity rule.

Your social worker

Compares the oral and infusion cost-sharing in writing with the pharmacy team.

The care team

Confirms the drug is an oral anticancer medication and handles prior authorization.

Who decides
The health plan applies the law. TDI enforces it on complaint
Ask HR
“Is our plan fully insured and issued in Texas, and can you show me how its chemo-pill copay compares with the infusion benefit?”

How to apply

First step: Ask the plan in writing to compare your chemo-pill copay with the infusion copay and apply Texas law. Call TDI at 800-252-3439 if it refuses.

  1. Ask the plan in writing to compare your chemo-pill copay with its infusion cost sharing. If it refuses, call TDI at 800-252-3439.

Where it starts: Written request to the plan citing Insurance Code 1369.204; TDI 800-252-3439

What to gather

  • ID card and benefit booklet
  • HR's answer on fully insured versus self-funded
  • The pharmacy receipt and the infusion explanation of benefits

How long: A written plan answer within the plan's grievance deadline. A TDI complaint runs alongside.

What a yes looks like

The copay reset to the infusion level and a refund of the difference.

What a no looks like, and the next move

Ask the plan which exclusion applies. Marketplace and self-funded plans follow their own drug coverage rules.

Watch out

  • Marketplace plans and self-funded employer plans are outside this Texas law, and the law's list does not name the teacher and state-employee plans (TRS-ActiveCare, HealthSelect). Ask the plan what its own drug tiers say.
  • Parity is not $0: it means no worse than the infusion side of the plan.
  • Prior authorization and formulary rules still apply.
  • TRS-ActiveCare and ERS have separate appeal procedures. TRS’s administrator removed medical prior authorization for its administrative-services arrangement in September 2024; that does not settle every benefit or local public plan. Ask which document applies.

If they say no, quote this: Insurance Code 1369.204 (oral anticancer cost-sharing no less favorable than intravenous); applicability in 1369.202.

The numbers and the rules

The arcane layer, kept on purpose. Checked September 10, 2026.

What it is worth

Pharmacy cost-sharing for an oral anticancer drug no worse than the plan's infusion cost-sharing. No dollar cap in the Texas law.

Legal protection: Oral-versus-infused anticancer cost-sharing parity on state-regulated plans

What it costs the family: Plan cost-sharing stays within the parity rule.

The eligibility facts, as published

Plan
state-regulated fully insured plan
Excluded
qualified health plans through an exchange (1369.203(b)); self-funded plans; Medicaid; CHIP
Public employee plans
not named: the 1369.202 applicability list covers insurers, HMOs and similar carriers only and does not name the ERS (ch. 1551), TRS-Care (1575), TRS-ActiveCare (1579) or UT/A&M (1601) plans; ask the plan for its own policy

The trap: Marketplace (exchange) plans are excluded by 1369.203(b). Self-funded employer plans are not bound by Texas law.
