Reconstruction for facial paralysis using dynamic slings.

The assistant unit fee is $12.51 (). The calculation of time units is detailed in the General Preamble (). - Anaesthetist (Suffix C): The anaesthetist fee is calculated based on 6 base units () plus time units.

When to Use
- Use R532 when performing a dynamic facial sling procedure, such as a temporalis muscle transfer, to restore facial animation in patients with permanent facial paralysis.
- Select R532 specifically for dynamic reconstruction; do not use this code for static facial suspension procedures, which are billed under different musculoskeletal or plastic surgery codes.
Common Pitfalls
- Billing R532 alongside R531 or R533 for the same anatomical site during the same operative session will trigger a rejection for duplicate or overlapping services.
- Failing to correctly calculate assistant and anaesthetist units using the 6-unit base as defined in N28 is a frequent cause of payment discrepancies.
Billing Tips
- When performing bilateral procedures, ensure you only claim the base units for the major procedure as per GP85 and GP93, rather than doubling the base units for the assistant or anaesthetist.
