95913 in Detail
CPT 95913 sits at the top of the nerve conduction series, covering 13 or more studies. Because it represents the most extensive testing in the family, it is the code payers examine most closely.
Defending it requires documentation that enumerates each nerve tested and the type of study performed on it, alongside a clinical indication that justifies testing at that extent. The lower count code is 95911, the preconfigured array code is 95905, and neurology billing covers how the counts are documented.
Using 95913 Correctly
Documentation Requirements
Ensure clinical notes clearly support the level of service, procedure performed, and medical necessity for this CPT code.
Modifier Requirements
Determine whether any modifiers are required for this code, particularly in bilateral, assistant surgeon, or multiple procedure scenarios.
Payer-Specific Rules
Check payer fee schedules and coverage policies, as reimbursement and coverage rules for this code vary by payer.
Bundling Considerations
Review NCCI edits to confirm this code is not bundled with other procedures billed on the same date of service.
95913 Reference
| Field | Details |
|---|---|
| CPT Code | 95913 |
| Official Descriptor | Nerve conduction studies; 13 or more studies. |
| What It Covers | Nerve conduction testing where 13 or more studies were performed, the highest band in the series. |
| How a Study Is Counted | A sensory conduction test, a motor conduction test with or without an F wave, or an H-reflex test, counted once per anatomically distinct and separately named nerve. |
| Why It Is Reviewed | As the top of the series this code attracts the most scrutiny. The documentation must list every nerve tested and the study type for each so the count can be verified. |
| Medical Necessity | The clinical question must justify the extent of testing performed. Extensive studies without a supporting indication are a common target for post-payment review. |
| Common Denial Cause | Documentation that does not enumerate the studies performed, leaving the count unverifiable, or testing extent that exceeds what the clinical presentation supports. |
