Billing tips

Always append laterality modifiers (LT or RT) to avoid automatic claim denials; this is a mandatory requirement for all bilateral procedure codes
Impact: Prevents 100% of claims denials due to missing laterality information, saving resubmission delays of 14-30 days
Document time, complexity factors, and specific reasons if the procedure required significantly more work than typical cases to support modifier 22
Impact: Successful modifier 22 appeals can increase reimbursement by $116-$233 (20-40% above base $583.21 rate)
Separately report and bill for any associated rotator cuff repair (29827) or labral repair (29806) if performed during the same session with modifier 51
Impact: Additional reimbursement opportunity; secondary procedure pays at 50% of its fee schedule amount
Verify that the dislocation is truly acute (not recurrent/chronic) as CPT 23660 specifically applies to acute presentations; chronic instability requires different codes
Impact: Using incorrect code for chronic conditions (23455, 23462) results in claim denials and potential $200-400 payment differences
Capture all facility charges separately when performed in hospital setting, as the facility rate and non-facility rate are identical ($583.21) for physician component only
Impact: Ensures hospital receives separate facility fee of $3,000-$8,000 in addition to physician professional component
Document failed closed reduction attempts or specific contraindications to closed reduction to support medical necessity of open approach
Prevents medical necessity denials that could result in 100% loss of the $583.21 reimbursement

Frequently asked questions

What is the Medicare reimbursement rate for CPT 23660 in 2025?

The 2025 Medicare national average reimbursement for CPT 23660 is $583.21 for both facility and non-facility settings. This rate is based on 18.03 total RVUs multiplied by the 2025 conversion factor of 32.3465.

What is the difference between CPT 23660 and 23655?

CPT 23660 is for open treatment of acute shoulder dislocation requiring surgical incision and direct visualization, while CPT 23655 covers closed treatment of shoulder dislocation requiring anesthesia. Code 23660 is used when the dislocation cannot be reduced by closed methods or requires open repair of associated injuries.

Can CPT 23660 be billed with rotator cuff repair codes?

Yes, if a rotator cuff tear is identified and repaired during the acute dislocation surgery, you can bill the appropriate rotator cuff repair code (such as 29827 for arthroscopic repair) separately with modifier 51. Documentation must clearly support that both procedures were medically necessary and performed.

How many RVUs is CPT code 23660 worth?

CPT 23660 has 18.03 total RVUs for 2025, consisting of 7.66 work RVUs, 8.85 practice expense RVUs, and 1.52 malpractice RVUs. This relatively high RVU value reflects the complexity and risk of open shoulder dislocation surgery.

Is CPT 23660 an inpatient or outpatient code?

CPT 23660 can be performed in either inpatient or outpatient settings depending on patient factors and associated injuries. The Medicare reimbursement is the same ($583.21) regardless of setting, though facility fees differ significantly between hospital inpatient, hospital outpatient, and ASC locations.

What documentation is required to bill CPT 23660 instead of closed reduction?

Documentation must include evidence that open treatment was medically necessary, such as failed closed reduction attempts, associated fractures requiring open fixation, soft tissue or neurovascular injuries requiring repair, or anatomical factors preventing closed reduction. The operative report must describe the open surgical approach and reduction technique.

Does CPT 23660 include treatment of associated fractures?

CPT 23660 covers the open treatment of the shoulder dislocation itself. Associated fractures requiring separate fixation (such as glenoid rim fractures or greater tuberosity fractures) may be separately billable using appropriate fracture repair codes, typically with modifier 51 for multiple procedures.
