What 29365 covers

A cylinder cast stabilizes the knee by extending around the leg above and below the joint, while leaving the foot free. Orthopedic clinicians and emergency physicians may apply one for selected knee injuries, including patellar fractures, when the treatment plan calls for cast immobilization rather than a brace or a cast that includes the foot. The service is typically performed in an office, emergency department, or other setting where the cast can be fitted and molded.

Select 29365 for the cylinder configuration, not solely because the knee is being treated. Document the indication, laterality, and cast extent so the record shows that the foot was left uncovered. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When bilateral casts are reported with modifier 50, CMS pays at 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures at 50%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

29365 billing questions

How does a cylinder cast differ from a long leg cast?

A cylinder cast immobilizes the knee while leaving the foot uncovered. A long leg cast extends to the foot; select based on the cast actually applied.

Can 29365 be reported for casts on both knees?

For bilateral cylinder casts, report modifier 50. CMS pays bilateral procedures at 150%.

Does the 0-day global period include same-day care?

Yes. Same-day preoperative and postoperative care is included in the procedure's 0-day global period.

Can an assistant or co-surgeon be reported?

CMS does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.

What documentation supports choosing 29365?

Record the knee-related indication, laterality, and cast configuration and extent, including that the foot remains uncovered.

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.
