What 27299 covers

CPT 27299 is reported for an operative service involving the pelvis or hip when no specific CPT procedure code describes the work performed. A surgeon uses it for work in this anatomic area that is not represented by a named procedure code; it is not a substitute for a specific code that fits the operation. The operative report should identify the indication, site, approach, techniques, and work performed, and explain why a specific code does not describe it.

Medicare assigns status C: CMS publishes no national physician fee schedule payment, and the Medicare Administrative Contractor sets payment for each claim and determines the global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. For a bilateral procedure reported with modifier 50, payment is at 150%.

How to choose

27284Hip fusion
This code describes hip joint arthrodesis. Use it when the documented operation is a hip fusion that fits that code, rather than an unlisted operation.
27278SI joint fusionIntra-articular implants
This code describes sacroiliac joint arthrodesis with an intra-articular device. It is specific to that procedure, not a general code for unlisted pelvis or hip surgery.
27280SI joint fusionOpen, grafted, instrumented
This code describes open sacroiliac joint arthrodesis with bone graft and instrumentation. Choose it when those features match the operation performed.
27282Pubic fusionSymphysis pubis
This code describes arthrodesis of the pubic symphysis. It applies to that specific fusion, not to other unlisted pelvic procedures.

27299 billing questions

When should I report this instead of a specific pelvis or hip code?

Use it when no specific CPT code describes the operation performed. For example, report a coded hip arthrodesis or sacroiliac joint fusion with its specific code when that code fits the procedure.

What documentation should accompany the claim?

The operative report should describe the indication, site, approach, techniques, and work performed. Explain why a specific code does not describe the operation.

Does modifier 50 apply to a bilateral procedure?

For a bilateral procedure reported with modifier 50, Medicare payment treatment is 150%.

How does Medicare price this code and set its global period?

The code has physician fee schedule status C, so CMS publishes no national payment and the Medicare Administrative Contractor sets payment for each claim. The contractor also determines the global period.

How are multiple procedures treated in the same session?

The highest-valued procedure is paid in full, and other procedures are paid at 50%.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
