Billing tips

Bill facility charges separately using revenue codes for microsurgical equipment, operating room time (8-16 hours), and specialized instruments; these can exceed $50,000-$100,000
Impact: Hospital facility reimbursement typically 10-20x the physician fee; ensures full capture of institutional costs
Document total operative time, ischemia time of amputated part, and specific structures repaired (number of arteries, veins, nerves, tendons) to support medical necessity and potential modifier 22
Impact: Detailed documentation can support additional $766-$1,915 payment with modifier 22 for increased complexity
Verify patient's commercial insurance pre-authorization requirements immediately upon presentation; many payers require notification within 24-48 hours even for emergency procedures
Impact: Prevents denials on claims averaging $3,830.80-$15,000+ when out-of-network or authorization requirements not met
Use diagnosis codes from S68.41- series (complete traumatic amputation at wrist level) with appropriate 7th character for initial encounter (A); link to external cause codes (W or V codes)
Impact: Proper diagnosis coding establishes medical necessity and prevents denials; missing external cause codes trigger payer audits
Do not separately bill nerve repairs (64834-64840), tendon repairs (26356-26358), or vascular repairs (35207-35286) when included in the replantation; these are bundled services
Impact: Prevents unbundling denials and potential fraud investigations; avoiding improper additional billing of $2,000-$8,000 in bundled codes
Bill postoperative visits within 90-day global period as included; code includes routine follow-up, dressing changes, and therapy monitoring unless complications require return to OR
