Use your code books and write your reasoning before opening the walkthrough. This exercise contains no real patient information.

Initial order

Fictional adult undergoes an ordered laboratory study that identifies a monoclonal protein band. The result is released to the treating practitioner. The authenticated order contains the initial study only; no conditional typing order is documented.

Proposed follow-up

The laboratory’s local workflow would automatically add another assay to identify the protein type whenever a band is found. Staff ask whether this can be treated like the specific implicit reflex examples described by NCCI.

Clinical record

No treating-practitioner request for the additional typing appears in the record. The available specimen could be used, but specimen availability does not establish whether the clinician needs that further test. The coder must not infer the missing order from the abnormal result alone.

Review decision

Evaluate the proposed routine typing under NCCI’s distinction between reflex relationships and other additional testing. The case asks for the next reporting decision; it does not invite the coder to determine clinical necessity or create an order for the practitioner.

Your coding worksheet

Identify what the original order establishes.
Distinguish this follow-up from the listed implicit reflex examples.
Determine what is missing before routine additional testing.
Explain why the positive result and available specimen are insufficient.

In your notebook, record the supported facts, your index route, the instructions you checked, and any missing detail that limits your answer.

Compare with the worked explanation

The order establishes the initial study only.
NCCI specifically treats monoclonal protein typing as additional testing not implicit in that initial order.
A treating-practitioner order is needed for the proposed additional test.
Neither an abnormal result nor retained material supplies that authorization.
