Historically code 98942 is frequently targeted by auditors because many providers adjust full spine without having documentation which supports and establishes the medical necessity for all five regions. Essentially, you must have documentation which addresses each area with a patient complaint, relevant objective findings, a clear plan for resolution, and demonstrable progress.
