Code is covered without prior authorization (high confidence)
Documentation Required
- A face-to-face encounter and a Written Order Prior to Delivery (WOPD) are required for the HCPCS codes specified under Final Rule 1713; claims lacking these per the LCD-related Standard Documentation Requirements Article will be denied.
- For add-on ensifentrine (J7601) therapy, the treating practitioner must document continuation of dual or triple maintenance therapy and either (a) history of continued COPD exacerbations within 12 months evidenced by hospitalization, ER visit, or new prescription for systemic glucocorticoids or antibiotics, or (b) during one exacerbation a combination of at least three clinical parameters (dyspnea VAS >5, respiratory rate >24 bpm, heart rate >95 bpm, oxygen saturation decline >=3% from baseline, or CRP >10 mg/L); also document persistent COPD-related dyspnea by persistent breathlessness or exercise limitation.
- A diagnosis code describing the condition necessitating nebulizer therapy must be included on each claim for equipment, accessories, and/or drugs.
Key Coverage Criteria
- Nebulizers are covered under the Durable Medical Equipment (DME) benefit when the reasonable and necessary (R&N) requirements in the related Local Coverage Determination (LCD) are met.
- Unfilled nebulizers (HCPCS A7007, A7017, E0585) filled with water or saline (A4217 or A7018) by the beneficiary or caregiver are an acceptable covered alternative.
- Add-on ensifentrine (J7601) therapy to dual LABA+LAMA maintenance therapy or LABA+LAMA+ICS triple maintenance therapy for COPD is covered when the treating practitioner documents continuation of maintenance therapy and the required exacerbation or dyspnea criteria in the medical record.
- CPT 94762 is medically necessary when intermittent arterial blood gas sampling is likely to miss important variations in the patient's respiratory status.
- CPT 94762 is medically necessary when the patient has hypoxemia and there is a need to assess supplemental oxygen requirements and/or a therapeutic oxygen regimen.
- Molecular syndromic infectious disease panels are covered when billed with the appropriate proprietary CPT®/PLA code (or CPT® 87999 if no specific code exists) and accompanied by ICD-10-CM diagnosis codes that support medical necessity documented in the patient record.
