Neurology and Neurosurgery / How to code a recurrent HNP

Why This Topic Matters

Recurrent disc surgery is a common source of coding confusion, especially when repeat exposure occurs at the same interspace or alongside other spinal procedures. Clear awareness of the applicable CPT framework helps support accurate reporting and better documentation.

Article Sections

1. Recurrent HNP coding scenario

   Introduces the repeat-disc-surgery scenario and the general coding question it raises. The section frames the article’s focus on recurrent herniation at a previously treated level.

2. CPT guidance and reexploration concepts

   Summarizes CPT guidance on reexploration procedures and discusses how the article interprets the repeat-surgery framework. It also references timing, laterality, and the concept of a single interspace.

3. Multiple levels and add-on coding

   Covers reporting when recurrent findings involve more than one level and when additional segments are addressed. The section also touches on documentation needs related to level and bilateral involvement.

4. Concurrent spinal procedures and modifier use

   Discusses situations where other spinal procedures are performed at the same time as the reexploration procedure. It addresses general modifier handling and the relationship to additional procedure reporting.

5. Initial HNP and related coding distinctions

   Explains the distinction between initial and recurrent disc herniation coding at a high level. The section places the article’s repeat-procedure guidance in context with first-occurrence coding.
