Lengthening with circular external fixation (less than or equal to 6 cm)

When to Use

Use R975 for limb lengthening procedures involving circular external fixation where the total planned distraction length is 6 cm or less.
Select this code for pediatric or adult patients undergoing corrective osteotomy and gradual distraction via circular frame when the surgical intent is limited to the 6 cm threshold.

Common Pitfalls

Billing R975 when the planned lengthening exceeds 6 cm; this requires a different procedural code or may be considered an unlisted procedure if no specific code exists for the greater length.
Attempting to bill R975 in conjunction with other osteotomy codes without clear documentation of separate anatomical sites or distinct surgical procedures, which risks rejection for unbundling.
Failure to document the specific distraction goal in the operative report, which is essential for justifying the use of this specific code over other fixation or reconstruction codes.

Billing Tips

Always verify the patient's age at the time of the procedure to apply the appropriate age-based premium (e.g., AGE_PREMIUM_UNDER_16_YEARS), as these are significant percentage add-ons to the $438.00 base fee.
If the procedure is performed as a non-elective trauma surgery, ensure the Injury Severity Score (ISS) is documented in the chart to support the E420 trauma premium.
