What 42225 covers
This operation addresses a previously repaired cleft palate when additional palatal length is needed, often to improve separation of the oral and nasal cavities and speech-related function. A plastic, oral and maxillofacial, or other surgeon experienced in cleft and craniofacial surgery typically performs it in an operating room. A pharyngeal flap is a recognized example of a secondary lengthening approach associated with this code.
Select the code when the operative report supports secondary cleft-palate reconstruction involving lengthening, rather than an initial repair or a different palate-lengthening service. Document the prior cleft repair, the functional or anatomic problem, the technique, and the structures treated. Medicare includes the day-before preoperative visit and 90 days of related postoperative care in the major-surgery global period. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate; an assistant at surgery may be paid, but co-surgeons and team surgery are not permitted.

42225 billing questions
What documentation supports reporting this code?
The operative report should establish the prior cleft repair, the reason further lengthening is needed, and the procedure and tissues addressed. Document the technique, including a pharyngeal flap when used.
Are routine postoperative visits separately reported?
Related postoperative care during the 90-day global period is included. The day-before preoperative visit is also included.
Should modifier 50 be appended for bilateral work?
No. The code's descriptor and anatomy make a bilateral adjustment inappropriate.
Can an assistant or another surgeon be reported?
Medicare may pay for an assistant at surgery. Co-surgeons and team surgery are not permitted for this code.
What happens when other procedures are performed in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction. The operative record should distinguish the services performed.
