Voiding diaries documenting baseline and test-stimulation outcomes are required to measure the ≥50% improvement for urinary indications.
For fecal incontinence, documentation must show frequency (>2 incontinent episodes/week), duration (>6 months or >12 months after vaginal childbirth), and failure or intolerance of conventional therapies.
A percutaneous test stimulation report documenting at least 50% sustained (>1 week) improvement is required to support permanent implantation for fecal incontinence.
Medical records must document that the patient is refractory to conventional therapy (behavioral, pharmacologic and/or surgical) for urinary indications and is an appropriate surgical candidate able to undergo anesthesia.

Sacral nerve stimulation (SNS) is covered for urinary urge incontinence.
SNS is covered for urgency-frequency syndrome (urinary urgency-frequency).
SNS is covered for urinary retention.
Both a temporary test stimulation and subsequent permanent implantation of an implanted sacral electrode array are covered for appropriate candidates.
SNS is covered for fecal incontinence when all fecal-specific criteria are met (see limitations/frequency): chronic fecal incontinence with >2 incontinent episodes/week and duration >6 months or >12 months after vaginal childbirth.
Coverage for fecal incontinence requires documented failure or intolerance to conventional therapy (e.g., dietary modification, bulking agents, pharmacologic treatment).
