Summary & Overview
CPT 0547T: Tibial Reference Point Indentation for Bone Quality Assessment
CPT code 0547T represents an invasive diagnostic procedure that inserts a reference point indenter into the tibial shaft to measure bone stiffness and toughness, producing a quantitative score. This measurement can inform preoperative planning for joint replacement and help assess fracture risk in patients with osteoporosis or osteopenia. Nationally, the code is relevant as interest grows in objective bone quality metrics to complement imaging and bone mineral density tests.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis covers coverage and billing considerations across major commercial payers and Medicare, identifying where policy updates or coding guidance may affect clinical adoption and reimbursement workflows.
Readers will find a concise briefing on the clinical purpose and typical settings for the service, common billing modifiers, and where to look for supporting documentation. The publication also outlines benchmarks and policy themes relevant to payers and providers, and highlights practical coding and documentation points to consider when reporting CPT code 0547T for bone quality assessment in joint replacement planning and fracture-risk evaluation.
Billing Code Overview
CPT code 0547T describes the insertion of a reference point indenter through the skin into the shaft of the tibia to assess bone stiffness and toughness. Results are reported as a score that may provide bone quality information useful for planning joint replacement surgery and evaluating fracture risk in patients with osteoporosis or osteopenia.
Service type: Diagnostic bone quality assessment using invasive reference point indentation
Typical site of service: Ambulatory surgical center or hospital outpatient department

Clinical & Coding Specifications
Clinical Context
A 72-year-old woman with a history of osteoporosis is scheduled for primary total hip arthroplasty. Preoperative assessment raises concern about bone quality and risk of intraoperative fracture and implant subsidence. The orthopedic surgeon elects to perform a transcutaneous tibial reference point indenter test immediately prior to surgery in the preoperative holding area or in the operating room under the same anesthetic. The procedure involves insertion of a small reference point indenter through the skin into the tibial shaft to measure bone stiffness and toughness; the device yields a numeric score that informs intraoperative decisions such as implant selection, fixation method (cemented versus cementless), and need for adjunctive fixation.
Typical clinical workflow:
-
Patient arrives to preoperative area with informed consent completed for the primary joint replacement and ancillary bone-quality testing.
-
Pre-anesthesia verification and positioning for the test; local anesthesia or monitored anesthesia care may be used if performed awake, or the test may be performed after induction if done in the OR.
-
Skin antisepsis and sterile draping of the proximal tibia.
-
Provider identifies a reference point on the tibial shaft, inserts the indenter per device instructions, and records the quantitative bone quality score.
-
Results are documented in the operative or preoperative record and used to guide implant selection and fixation strategy during the joint replacement procedure.
-
Routine postprocedure dressing and monitoring for bleeding, infection, or pain; documentation of device score and any immediate complications.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | When work required is substantially greater than typical for the procedure (e.g., extensive time or complexity during indenter placement due to severe deformity). |
23 | Unusual anesthesia | When general anesthesia is administered for an otherwise normally non-anesthetized procedure. |
51 | Multiple procedures | When the indenter test is reported on the same day as other distinct procedures and multiple-procedure reporting rules apply. |
52 | Reduced services | When the indenter test is partially reduced or not completed as planned. |
53 | Discontinued procedure | When the test is started but stopped due to patient instability or unsafe conditions. |
54 | Surgical care only | When the reporting provider renders only the surgical portion of care and another provider reports pre/postoperative care. |
55 | Postoperative management only | When the reporting provider furnishes only postoperative management related to the test or subsequent surgery. |
62 | Two surgeons | When two surgeons of different specialties share the procedure, both contributing distinct skills for indenter placement or interpretation. |
73 | Discontinued outpatient procedure prior to anesthesia | When the test is canceled after patient preparation but before regional or general anesthesia and reported per payer rules. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | When an accredited assistant performs assisting tasks during placement in accordance with state law. |
