What 27648 covers

A physician, commonly a radiologist, places a needle or catheter into the ankle joint and injects contrast for an arthrogram. The injection precedes imaging used to assess the joint, such as radiography, CT, or MRI. Ankle arthrography may be requested to evaluate suspected cartilage or ligament injury, joint-surface abnormalities, or persistent symptoms after an ankle injury.

Select this code for the ankle-joint injection, not for an injection into another joint or for the imaging acquisition and interpretation. The record should identify the ankle, the clinical indication, and the intra-articular contrast injection. Report the imaging service separately when performed and documented; ankle arthrography imaging may be reported with 73615. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. 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 requires documented medical necessity; 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.

27648 billing questions

How is 27648 different from 73615?

27648 reports injection of contrast into the ankle joint. Code 73615 reports the radiographic arthrogram examination and its supervision and interpretation.

Can the ankle MRI be reported with the injection?

Yes, when an MRI is performed and documented, report the applicable MRI service separately. Code 73722 describes MRI of a lower-extremity joint with contrast.

Does this code apply to a knee or hip arthrogram?

No. This code is specific to the ankle joint; 27370 describes injection for knee arthrography, and 27093 describes injection for hip arthrography.

What documentation supports reporting 27648?

Document the ankle joint treated, the indication, and that contrast was injected intra-articularly to prepare for arthrographic imaging.

How is a bilateral ankle procedure reported?

Use modifier 50 for a bilateral procedure. CMS pays the bilateral procedure at 150%.

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.
