Documentation Required

Claims for swallowing studies should include documentation consistent with LCD L33449; this billing guideline is a complement to that LCD and providers should retain medical records supporting the medical necessity of the dysphagia evaluation.
Document evaluations and re-evaluations and bill re-evaluations using the evaluation CPT code (per policy guidance).
Document selection/prescription and programming/modification of speech-generating devices and use CPT 92607/92608 for selection/prescription and CPT 92609 for programming/modification on claims.

Claims and coding must follow the complementary Local Coverage Determination (LCD L34429) guidelines referenced in this policy.

Medical records must include history and physical notes, laboratory results, and documentation of signs and symptoms that warrant the head/neck diagnostic imaging.

Accurate HCPCS/CPT coding must be submitted to differentiate CT and MRI scans from other radiology services and to support coverage determinations.
