Otolaryngology
About 31243: Endoscopic posterior nasal nerve cryoablation
Endoscopic cryoablation of the posterior nasal nerve treats chronic rhinitis by targeting nasal nerve tissue through the nasal cavity.
An otolaryngologist uses a nasal endoscope to guide a cryoprobe to the posterior nasal nerve region and ablate the nerve tissue. The procedure is used for chronic rhinitis, including persistent nasal symptoms such as congestion and drainage, and may be performed in an office or facility setting. The code represents the cryotherapy approach, not radiofrequency treatment.
Report the service when the documented procedure uses endoscopic guidance and cryoablation of the posterior nasal nerve. Record the indication, endoscopic approach, cryotherapy technique, and treated sides. CMS prices this code as bilateral, so modifier 50 does not increase payment. It has a 0-day global period, which includes same-day preoperative and postoperative care. When related endoscopies are performed together, endoscopy family pricing applies. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

31243 billing questions
How does this differ from 31242?
Both codes describe endoscopic posterior nasal nerve ablation, but 31243 is for cryotherapy and 31242 is for radiofrequency treatment. Choose the code that matches the documented ablation method.
Should the code be reported once or once per side?
CMS prices 31243 as bilateral. Report the service once; modifier 50 does not increase payment.
What documentation supports 31243?
Document the chronic rhinitis indication, endoscopic access, use of cryotherapy to ablate the posterior nasal nerve, and the sides treated.
Can a diagnostic nasal endoscopy also be reported?
Endoscopic visualization used to guide the cryoablation is part of the surgical service. A separate diagnostic endoscopy requires a distinct, medically necessary service beyond that procedural guidance.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's 0-day global period.
Can an assistant or co-surgeon be billed?
Medicare does not pay an assistant at surgery for 31243. Co-surgeons and team surgery are not permitted.
