Head and neck surgery

About 42405: Incisional salivary gland biopsy

Report this service when a surgeon obtains salivary gland tissue through an incision for diagnostic evaluation rather than sampling it with a needle.

This code describes an incisional biopsy that obtains salivary gland tissue for diagnosis. An otolaryngologist, head and neck surgeon, or oral and maxillofacial surgeon may perform it when a gland abnormality needs tissue evaluation, such as a persistent mass or unexplained enlargement. The surgeon exposes the selected gland tissue and removes a sample; the procedure may take place in an office or a facility, depending on the clinical situation and operative approach.

Choose this code for incisional tissue sampling, not needle sampling or definitive removal of a gland or lesion. The note should identify the gland and side, the reason for biopsy, the incisional approach, and the tissue obtained. Histologic examination is a separate service when performed and separately reportable. The code has a 10-day global period, so related postoperative visits during that period are included. 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 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

42405 billing questions

How does 42405 differ from 42400?

42405 is for tissue obtained through an incision. 42400 is the needle-biopsy option; select the code that matches how the specimen was obtained.

Can the pathology examination be reported separately?

The biopsy code covers obtaining the specimen, not its microscopic evaluation. The pathology service may be reported separately when performed and otherwise reportable.

Can modifier 50 be used for biopsies on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code, so do not append modifier 50.

What postoperative care is included?

Related postoperative visits during the 10-day global period are included in the procedure payment.

How does the multiple-procedure rule affect payment?

When other procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are subject to the standard 50% reduction.

May an assistant or co-surgeon be reported?

Assistant-at-surgery payment is restricted for this code. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
