Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Coverage Criteria — Half-Tablet Program

The Half-Tablet benefit excludes medications that are controlled-release, delayed-release, or have a narrow therapeutic index. These formulation characteristics make a tablet inappropriate to split and therefore ineligible for the program.

Provider Actions & Prescribing Guidance

Note

Half‑Tablet prescribing requirement

Write prescriptions for qualified once-daily medications with directions to take 1/2 tablet per day. Specify the equivalent higher-strength tablet on the prescription so the patient fills the stronger product but takes half the tablet daily.

Documentation Required

Patient selection before prescribing

Consider patient and caregiver ability before prescribing a half‑tablet regimen. Screen for limited dexterity, tremor, reduced hand strength, poor vision, or cognitive impairment that could prevent safe splitting or correct dosing. Counsel patients on proper splitting technique and provide a pill splitter when appropriate; avoid half‑tablet prescriptions for patients who cannot reliably split or identify doses.

Billing Rule

How to write the prescription

Prescribe the higher‑strength tablet with directions to take 1/2 tablet once daily and adjust the quantity to reflect the number of whole tablets needed (e.g., to replace Crestor 20 mg daily for 30 days, prescribe Crestor 40 mg — Take 1/2 tablet once daily — Qty = 15). Include clear directions and, when supported by local rules, note ‘split tablet’ on the prescription.

Denial Risk

Ineligible formulations/characteristics

Do not use the Half‑Tablet approach for formulations or products that are inappropriate to split. Ineligible characteristics include controlled‑release, extended‑release, delayed‑release, enteric‑coated formulations, or any product with a narrow therapeutic index where splitting may alter delivery or safety. If the medication is listed as ineligible, prescribe the appropriate strength without splitting.

Initial Prescribing Instructions

Initial prescribing instructions

Formulation restrictions: Do not initiate a half‑tablet prescription for formulations that are controlled‑release, delayed‑release, or have a narrow therapeutic index—these are excluded from the Half‑Tablet benefit.

Selection rules explicitly exclude CR/DR/NTI formulations.

Assessment Before Initiation

Assessment item	Action / counseling
Dexterity and hand strength	Screen patient or caregiver for fine motor ability to split tablets reliably; provide or recommend a pill‑splitter if needed and offer hands‑on demonstration.
Vision	Confirm adequate vision to identify and align tablets for splitting; provide large‑print instructions or caregiver assistance if vision is limited.
Cognitive ability	Assess understanding of dosing schedule and ability to select the correct tablet to split; avoid half‑tablet regimens or arrange caregiver support if cognition is impaired.
Caregiver availability	If the patient cannot manage splitting, confirm a capable caregiver is available and provide counseling on proper splitting and administration.
Provide pharmacist counseling	Recommend pharmacist counseling on tablet splitting, safe storage of halves, and confirming the correct strength and dose when dispensing.

Background

Tablet splitting is used to achieve intermediate doses or reduce cost by prescribing a higher-strength tablet and instructing the patient to take half. The program applies only when there is an expected cost savings, the medication is dosed once a day, and the formulation is appropriate for splitting (not controlled-release, delayed-release, or narrow therapeutic index). Providers should confirm the patient can safely split and manage half-tablet dosing before using this approach.

Definitions & Not Appropriate For Splitting

Controlled‑release, delayed‑release, and narrow therapeutic index formulations — Not appropriate for splitting

Excluded formulationsControlled-release (CR) medications are not appropriate for tablet splitting and are excluded from the Half-Tablet benefit.

Excluded formulationsDelayed-release (DR) medications are not appropriate for tablet splitting and are excluded from the Half-Tablet benefit.

Excluded characteristicsMedications with a narrow therapeutic index (NTI) are not appropriate for tablet splitting and are excluded from the Half-Tablet benefit.
