Lesson Notes

Read through the key concepts before you try the challenge.

Rejections are a language worth learning

On the job

A claim rejects at the counter with a patient waiting.

The code means refill too soon. The patient believes they are out. Both can be true — they may have been taking more than prescribed, the days supply may have been entered wrong, or they may have lost the bottle. What you do next depends on which.

Your task: Learn what the common rejections mean, so you can resolve them rather than relay them.

Rejection	Usually means	Typical resolution
Refill too soon	Not enough days have elapsed	Check days supply; the patient may return later, or a vacation override may apply
Prior authorization required	Plan needs approval first	Contact the prescriber to initiate it
Non-formulary	Plan does not cover this drug	Pharmacist may contact prescriber about an alternative
Invalid member ID	Data entry or coverage change	Re-verify the card, both sides
Quantity limit exceeded	Plan caps the amount	May need prior authorization or a smaller quantity
NDC not covered	That package or manufacturer is excluded	Try an equivalent NDC if available

Common rejections and what they usually mean

Schedule	Characteristics	Examples
C-I	No accepted medical use in the US	Not dispensed in retail pharmacy
C-II	High abuse potential; accepted medical use	Oxycodone, morphine, amphetamine
C-III	Moderate potential	Certain codeine combinations, ketamine
C-IV	Lower potential	Alprazolam, lorazepam, zolpidem
C-V	Lowest potential	Some antidiarrheals and cough preparations with codeine

Controlled substance schedules

Controlled substances carry record-keeping requirements that ordinary drugs do not: perpetual inventory for C-II, separate or dispersed storage, specific forms for ordering, and inventory counts on a defined schedule. Requirements come from both the DEA and your state, and where they differ the stricter applies. Discrepancies in a controlled count are reported immediately and never adjusted quietly to make the numbers agree.

HIPAA applies fully in a pharmacy, and the counter is where it is hardest. A pharmacy is a public space with a queue, so patient names, medications, and conversations are easily overheard. Lower your voice, do not read a medication name aloud, and never discuss a patient's prescriptions where the next person in line can hear. What someone is collecting is itself protected information.

Check your understanding

A claim rejects as “refill too soon” and the patient insists they have run out. What is the appropriate step?

Challenge

Apply what you've learned in this lesson.

Law and insurance are learned from the actual sources.

Find your state's requirements for controlled substance inventory and record retention.
Research what a DEA Form 222 is used for and when it is required.
Find five common rejection codes from a real payer and write down what each requires.
List four things about the physical layout or workflow of a pharmacy counter that affect patient privacy, and what you would do about each.
