If AMA owns the copyrights to CPT® and descriptions:

Why do the descriptions and CCI edits differ? Ex: CPT® 69990. Per CCI you can never bill CPT® 63030 with CPT® 69990, but the CPT® book states that it is not inclusive. Or am I see this wrong? Somebody please advise. Thank you.

re: If AMA owns the copyrights to CPT® and descriptions:

Owning the copyright and description is not the same as owning POLICY. The only code set that has rules that MUST be followed is ICD-10, per HIPAA. CMS can set whatever policy they choose within Medicare law for CPT® codes.
