Billing tips

Document all anatomical areas imaged with specific view counts in the radiology report
Impact: Prevents 52 modifier downcoding and potential $24-48 reduction in reimbursement
Verify medical necessity diagnosis codes align with accepted indications (multiple myeloma C90.00, metastatic bone disease C79.51, suspected child abuse T74.12XA)
Impact: Increases clean claim rate by 35-40% and reduces denial frequency
Bill 77075 only once per session regardless of number of films; do not unbundle into individual anatomical X-rays
Impact: Prevents recoupment of entire $96.07 payment plus potential fraud investigation
When pediatric skeletal survey is incomplete due to patient cooperation, use modifier 52 and document attempted views
Impact: Allows partial reimbursement rather than complete denial; typically 50-75% of full fee
For follow-up skeletal surveys in multiple myeloma, ensure adequate time interval (typically 3-6 months) and document clinical reason for repeat
Impact: Prevents medical necessity denials that would result in $96.07 payment loss
Separate professional and technical components when radiologist is not employed by facility performing technical service
Impact: Ensures proper payment distribution and prevents coordination of benefits issues

Frequently asked questions

What is the 2025 Medicare reimbursement rate for CPT 77075?

The 2025 Medicare national average reimbursement for CPT 77075 is $96.07 for both facility and non-facility settings, based on 2.97 total RVUs and the $32.3465 conversion factor.

How many X-ray views are required for a complete skeletal survey?

A complete skeletal survey typically requires 20-30 separate radiographic views covering all major skeletal regions including skull, entire spine, pelvis, chest, and all extremities. The exact number varies based on protocol (adult vs. pediatric) and clinical indication.

Can I bill CPT 77075 with individual bone X-ray codes on the same day?

No, CPT 77075 is a comprehensive code that includes imaging of all skeletal regions. Billing individual anatomical X-ray codes (such as 73030 for shoulder or 73620 for foot) with 77075 on the same encounter constitutes improper unbundling and will result in denials or recoupment.

What diagnosis codes support medical necessity for CPT 77075?

Common supporting diagnoses include multiple myeloma (C90.00), secondary malignant neoplasm of bone (C79.51), suspected child abuse (T74.12XA), metabolic bone disease, Paget's disease (M88.9), and evaluation for polyostotic fibrous dysplasia. Single-site pain or trauma typically does not justify complete skeletal survey.

How often can a skeletal survey be repeated for Medicare patients?

Medicare does not specify a hard frequency limit, but repeat skeletal surveys generally require 3-6 month intervals for cancer staging follow-up. More frequent imaging requires strong documentation of clinical change, new symptoms, or treatment monitoring protocols. Same-day repeats need modifier 76 with documented technical or clinical reason.

What is the difference between CPT 77075 and 77074?

CPT 77075 is a complete (comprehensive) skeletal survey imaging the entire skeleton, while 77074 is a limited skeletal survey covering specific regions or fewer views. Code selection depends on the extent of imaging performed and documented medical necessity for comprehensive versus targeted evaluation.

Do I need modifier 26 or TC when billing CPT 77075?

Use modifier 26 when billing only the professional component (radiologist interpretation) if your practice does not own the equipment. Use modifier TC for the technical component (facility, equipment, technologist) when billed separately. Bill without modifiers only when the same entity provides both components (global service).
