Not covered — cosmetic / not medically necessary for restoration of erectile function with nerve grafting.

Coverage rationale: Autologous (e.g., sural) or allogenic nerve grafts to restore erectile function during or after radical prostatectomy are unproven and not medically necessary due to insufficient evidence of efficacy.

Denial Risk

Denial likely for surgical nerve grafting to restore erectile function

Claims for nerve grafting procedures when intended to restore erectile function after radical prostatectomy are unlikely to be approved under this policy because autologous or allogenic nerve grafts for this indication are considered unproven and not medically necessary due to insufficient evidence of efficacy.

Autologous nerve grafting (e.g., sural nerve grafting) for erectile function
Allogenic nerve grafting for erectile function

Background & Evidence Summary

Nerve grafting (for example, sural nerve grafting) has been proposed to bridge resected cavernous nerves during radical prostatectomy to restore spontaneous erectile function when neurovascular bundles are resected. The procedure involves harvesting a donor nerve (commonly the sural nerve) and grafting it to the distal and proximal ends of the resected cavernous nerve.

The policy concludes there is insufficient high-quality evidence demonstrating that nerve grafting improves erectile function after radical prostatectomy; available randomized data were stopped early for lack of benefit and observational studies are limited by design.

A randomized trial (Davis et al., 2009) was stopped early after an interim analysis showed no increase in potency at two years with unilateral sural nerve grafting compared to control; the trial was terminated due to slow accrual and a low probability of showing a benefit.

Multiple case series and nonrandomized observational studies report mixed results but are limited by small sample sizes, lack of comparison groups, baseline differences between groups, and potential bias; these limitations prevent definitive conclusions about efficacy.

Systematic and narrative reviews have noted promising signals in some microsurgical approaches but emphasize that the studies lack adequate comparators and sufficient size to make firm claims.

NCCN (2025) states that replacement of resected nerves with nerve grafts does not appear to be effective for patients undergoing wide resection of the neurovascular bundles.
