Current Procedural Terminology® (CPT) Modifier 52
Identifies a service or procedure that was partially reduced, that services performed were significantly less than usually required, or eliminated at the discretion of the provider.
Procedure codes submitted with modifier 52 will be reimbursed at a reduced rate. Our health plan reimburses procedure(s) appended with modifier 52 at 50% of the allowable amount. Procedure codes for any other procedure not performed at all should not be additionally reported.
When an inherently bilateral procedure is performed unilaterally, resulting in the service being reduced, (such as 22840 – spinal instrumentation), modifier 52 should be reported.
When a procedure code does not exist to report a lower level of service, modifier 52 may be reported (such as 73520-Radiological examination, hips, bilateral, minimum of 2 views of each hip, but only one view of each hip was performed).
Our health plan considers the following, but not limited to, inappropriate usage for modifier 52:
- Time based codes
- All-or-nothing procedure codes (e.g. 72020 XR spine, single view; 97010 – 97028 PT modalities, one or more areas, non-timed codes)
- Unlisted procedure codes
Evaluation and management (E&M) codes
- Select the code that best describes the level of service performed. If services documented do not meet the criteria for the lowest level of E&M available, then the service is not reportable
Procedure code/modifier combinations that are considered not valid for our health plans use will be denied.
