Prior Authorization
No Prior Auth Required
No active coverage policies found for this code (low confidence)
Documentation Required
- Medicare contractors may require operative notes, reports of standing x-rays, and/or arthroscopy results to define the patient’s knee condition when adjudicating coverage.
- For services requiring a referring/ordering physician, the name and NPI of the referring/ordering physician must be reported on the claim.
- A valid ICD-10-CM diagnosis code that best describes the patient's condition must be submitted on the claim; claims without a valid ICD-10-CM code will be returned as incomplete under Section 1833(e).
- An Advance Beneficiary Notice of Noncoverage (ABN) may be used for outpatient services likely to be non-covered; follow CMS Claims Processing Manual Chapter 30 guidance when issuing ABNs.
Key Coverage Criteria
- Arthroscopic lavage or arthroscopic debridement for osteoarthritic knee in patients WITHOUT severe osteoarthritis who present with mechanical symptoms (eg, locking, snapping, popping), abnormal limb/knee alignment, or less severe/early degenerative arthritis may be considered for coverage at the discretion of the Medicare contractor.
- Nonvascular extremity ultrasound is covered when medical necessity is documented in the patient's record, including relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures.
- Diagnostic nonvascular extremity ultrasound is covered when the claim includes an ICD-10-CM diagnosis code that best describes the patient's condition and the test result or the symptoms prompting the test are documented.
- CPT codes 64400-64530 for peripheral nerve blocks may be reported on the date of surgery when performed for postoperative pain management only if the operative anesthesia is general anesthesia, subarachnoid injection, or epidural injection and the adequacy of intraoperative anesthesia is not dependent on the peripheral nerve block.
- Peripheral nerve block services that are separate, medically necessary services which cannot be rendered by the surgeon may be reported if the surgeon documents the reason for referral and the additional services are justified in the medical record.
- Simultaneous bilateral hip or knee replacement during the same encounter is covered when medical necessity for bilateral procedure is documented; bilateral procedures are subject to bilateral pricing.
