`T56.821S`, Toxic effect of gadolinium, accidental (unintentional), sequela

ICD-10-CM

Prior Authorization

No Prior Auth Required

Covered without prior authorization (high confidence)

Documentation Required

This article provides billing/coding guidelines that complement Local Coverage Determination L34417 for CT of the head; consult LCD L34417 for specific coverage, coding, and documentation requirements.
Follow LCD L35434 for reasonable and necessary requirements and supporting medical documentation for oximetry services.
Report overnight oximetry using CPT code 94762 on claims.

A specific written order (referral/prescription) by the physician or appropriate NPP must be on file for all respiratory care services.

Medical records must fully document that services were reasonable and medically necessary, with results and usage of the test documented in the record and available upon request.

Each claim must be submitted with ICD-10-CM code(s) that reflect the patient's actual condition; listing a diagnosis code alone does not justify the test without supporting clinical context.
