Question:
Do we need a modifier for submitting claims for the screening of Medicare beneficiaries diagnosed with pre-diabetes?
Answer:
You must append modifier TS to the CPT code when submitting claims for screening of Medicare beneficiaries diagnosed with pre-diabetes (previous fasting glucose level of 100–125 mg/d or a two-hour post-glucose challenge of 140–199 mg/dL). This modifier communicates to the intermediary, A/B MAC or carrier that the allowed frequency of each six months applies to the claim.
