What 42410 covers
Code 42410 describes surgery to remove a lesion or tissue from the lateral portion of the parotid gland without formal dissection of the facial nerve. Otolaryngologists and head and neck surgeons commonly perform the operation in a hospital or ambulatory surgery setting for a localized parotid mass requiring excision rather than diagnostic sampling. The operative report should identify the site and extent of removal and describe the facial-nerve approach.
Choose this code when the resection is limited to the lateral lobe and the facial nerve is not formally dissected; use a different parotid code when the extent or nerve work differs. The service has a 90-day global period, including the day-before preoperative visit and related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose
- 42415Parotid excision
- Both involve lateral-lobe parotid surgery, but 42415 includes formal facial-nerve dissection and preservation. Use 42410 when that nerve dissection is not performed.
- 42420Parotid excision
- 42420 describes total parotid removal with facial-nerve dissection and preservation. It is not the limited lateral-lobe procedure reported with 42410.
- 42400Salivary biopsy
- 42400 is for salivary-gland biopsy and diagnostic tissue sampling. Use 42410 when the surgeon excises the lateral parotid lesion or gland tissue.
- 42408Salivary cyst
- 42408 describes excision of a salivary cyst. Use 42410 for excision involving the lateral parotid gland rather than a salivary cyst procedure.
42410 billing questions
How does 42410 differ from 42415?
Both describe lateral-lobe parotid surgery. Use 42415 when the surgeon formally dissects and preserves the facial nerve; 42410 is for lateral-lobe removal without that nerve dissection.
When is 42420 a better fit?
Use 42420 for removal of the entire parotid gland with facial-nerve dissection and preservation, rather than a lateral-lobe resection.
Can a parotid biopsy be reported instead?
A biopsy code describes diagnostic tissue sampling, not removal of the lateral lobe or a lesion as definitive surgery. Select the code that matches the actual procedure documented.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care. Do not separately report routine care included in that period.
How does Medicare treat bilateral reporting and multiple procedures?
Bilateral reporting with modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
