Broth Culture Testing for Interstitial Cystitis

Aetna considers broth culture testing for interstitial cystitis (IC; ICD-10 N30.10–N30.11) experimental/investigational and does not cover it for diagnosis or management. This determination is based on inadequate evidence of effectiveness and lack of support in major guidelines and reviews (e.g., AUA, UpToDate) showing no proven infectious etiology or benefit from antibiotics in typical IC.
