CPT code 23700 – Manipulation under anesthesia of the shoulder

Key takeaways

CPT Code 23700 covers shoulder joint manipulation under anesthesia, including a fixation apparatus when one is applied. Acute dislocation reduction is excluded.

Adhesive capsulitis (M75.01, M75.02) and shoulder contracture (M24.511, M24.512) are the strongest ICD-10 matches for medical necessity. Dislocation codes invite a denial.

CMS lists a 10-day global period (indicator 010) for the code, so routine post-procedure visits in that window are not separately billable.

Most commercial payers require prior authorization and typically want documented failure of 6 to 12 weeks of physical therapy.

Practice management software like Pabau checks eligibility, submits the claim through Claim.MD, and posts the remittance back to the patient record.

CPT Code 23700: official descriptor and procedure overview

CPT Code 23700 is defined by the American Medical Association (AMA) as: Manipulation under anesthesia, shoulder joint, including application of fixation apparatus (dislocation excluded). That parenthetical is a hard exclusion. Acute shoulder dislocations are reported with CPT 23655 instead.

An orthopedic surgeon or sports medicine physician performs the procedure while the patient is anesthetized. Anesthesia removes voluntary muscle guarding, so the surgeon can apply controlled force and break the adhesions or capsular contracture that limit range of motion.

A sling or shoulder immobilizer applied at the end of the procedure is bundled into CPT Code 23700. Check the operative note for a fixation line before the claim goes out, so the sling is never billed on its own.

What the code includes and excludes

Two unbundling errors come up again and again on this code. One is billing the fixation device separately, and the other is stacking arthroscopy codes on the same claim.

The anesthesia separation is especially important for multi-provider claims. The surgeon submits CPT Code 23700 under their NPI. The anesthesiologist submits the anesthesia code from the shoulder and axilla range (01610-01682) under their own NPI. Reporting the anesthesia service under the surgeon’s NPI misstates who performed it and invites an audit.

How manipulation under anesthesia is performed and documented

Payers review operative notes for CPT 23700 against a consistent checklist. A note that omits the anesthesia type or the range of motion (ROM) measurements invites a medical necessity dispute.

1. Patient positioning: Supine or lateral decubitus, shoulder exposed and accessible. Position documented in the operative note.
2. Anesthesia induction: General or regional anesthesia administered by the anesthesiologist. Type (general vs. interscalene block) documented by both providers.
3. Pre-procedure ROM assessment: Baseline range of motion in forward flexion, abduction, external rotation, and internal rotation measured and recorded while the patient is anesthetized.
4. Manipulation technique: The surgeon applies graduated force in the planes of restricted motion, progressively breaking adhesions. Force direction and planes documented.
5. Post-procedure ROM assessment: Immediate post-manipulation range of motion measured and compared to pre-procedure baseline.
6. Fixation application (if applicable): Sling or immobilizer applied; type and rationale documented.
7. Post-op plan: Physical therapy initiation timeline, pain management, and follow-up schedule documented.

Coders validating CPT 23700 claims should confirm all seven elements are present in the operative report. Missing ROM measurements before or after the manipulation are a frequent reason payers dispute the claim. For this code, the operative report is the claim’s primary defense.

ICD-10 codes that support medical necessity

Diagnosis code selection decides whether the claim passes initial medical necessity screening. Adhesive capsulitis codes are the strongest pairing. Dislocation codes paired with CPT Code 23700 will trigger a denial, because the descriptor excludes dislocation.

When M75.01 or M75.02 is the primary diagnosis, claims usually pass initial screening, provided conservative treatment failure is in the record. Pain-only codes (M25.511, M25.512) used alone tend to draw a medical necessity review letter.

Watch the neighboring M24.41- codes. They describe recurrent dislocation of the shoulder, not contracture, so they fall under the descriptor’s dislocation exclusion. Confirm the final code and its laterality against the ICD-10-CM code set before the claim goes out.

Modifiers for shoulder MUA claims

Modifier selection for CPT Code 23700 determines both reimbursement and claim routing. Nearly all payers require a laterality modifier. Bilateral billing rules are payer-specific, so verify them against the patient’s plan before submission.

For bilateral MUA on the same date of service, check the payer’s billing manual before appending -50. Medicare accepts -50 on a single line for CPT 23700. Many commercial payers require two separate line items with -RT on one and -LT on the other. The wrong format produces a denial that has to be fixed with a corrected claim, which an appeal alone won’t resolve.

Medicare reimbursement for CPT 23700

Medicare reimbursement for CPT Code 23700 is calculated using the Resource-Based Relative Value Scale (RBRVS). Payment varies by setting (facility vs. non-facility) and by geographic practice cost index (GPCI). Check current rates for your MAC jurisdiction with the CMS Physician Fee Schedule lookup tool. The table below shows how each payment component behaves by setting.

Commercial contracts often pay CPT Code 23700 as a percentage of the Medicare rate, so compare each remittance with your contracted fee schedule. Practice management software like Pabau includes claims management software that submits claims through Claim.MD to thousands of payers. ERA remittances then post back against each claim.

The 10-day global surgery period

The CMS Medicare Physician Fee Schedule lists CPT 23700 with global surgery indicator 010, a 10-day global period. That marks it as a minor procedure. The window covers the day of the procedure plus the 10 days that follow, 11 days in total.

Confirm the indicator in the fee schedule each plan year before advising on post-procedure billing. The timeline below shows which services fold into the package and which bill separately.

During the 10-day global period, the operating surgeon cannot bill these services separately:

• Routine post-procedure E&M visits related to the shoulder
• Post-procedure pain management by the surgeon
• Removing the sling or immobilizer applied at the procedure
• Writing the physical therapy referral (the therapy sessions themselves bill separately)

Some services can be billed separately during the window:

• An unrelated E&M visit for a new problem, with modifier -24
• A return to the operating room for a complication, with modifier -78
• An unrelated procedure during the window, with modifier -79
• Physical therapy sessions billed by the therapist under their own NPI

Record the global period end date on the patient’s chart at discharge. Any follow-up visit booked before that date then gets a modifier review before the charge is entered.

Prior authorization and medical necessity requirements

Most commercial payers require prior authorization for CPT Code 23700. Requirements vary by payer and plan. The criteria below are common across major insurers, including Aetna’s Clinical Policy Bulletin 0204 on manipulation under general anesthesia. Verify the criteria for each patient’s plan before the procedure is scheduled.

• Failed conservative treatment: Most payers require 6 to 12 weeks of documented physical therapy, typically two to three sessions a week, without meaningful ROM improvement
• Imaging: A shoulder X-ray is typically required to rule out fracture. Some payers also want an MRI to characterize soft tissue pathology
• ROM documentation: Quantified range of motion deficits in at least two planes, measured and recorded by the treating provider
• Physician order: Written order from the treating orthopedic or sports medicine physician linking the conservative treatment failure to the MUA indication
• Diagnosis specificity: M75.01 or M75.02 (adhesive capsulitis), or M24.511-M24.519 (shoulder contracture), as the primary ICD-10 code. Pain codes alone rarely win approval

Build the prior authorization process into scheduling, capturing the approval date, reference number, and approved CPT codes before the procedure is booked. A claim sent without a required authorization number is one of the most avoidable denials. Verify eligibility at least 48 hours before the date of service to confirm active coverage.

How 23700 differs from similar shoulder codes

The three most common miscoding errors involve confusing CPT Code 23700 with 23655 (shoulder dislocation), 29825 (arthroscopic lysis of adhesions), and 20610 (joint aspiration/injection). The table below shows when each code applies and whether the codes can be billed together.

Coders should check the 29825 pairing in the current AAPC CPT code reference and the CMS NCCI edit tables every plan year. Edit status on a code pair can change from one year to the next.

Common claim denial reasons and how to avoid them

CPT Code 23700 denials cluster around six recurring triggers. A pre-submission check catches each of them before the claim leaves the practice.

• Missing prior authorization: Submitting without a valid PA reference number when the payer requires one. Fix: Build a pre-surgery PA verification step into every MUA scheduling workflow. Never schedule the procedure without a confirmed approval number.
• Insufficient documentation of conservative treatment failure: The claim has no physical therapy records or notes quantifying ROM limitation over time. Fix: Collect PT records before submission. The operative note alone is not sufficient evidence of conservative treatment failure.
• Wrong ICD-10 code (dislocation mapped to 23700): Submitting a dislocation diagnosis, such as the S43.00- range or recurrent dislocation codes M24.411-M24.419, with CPT 23700. Fix: Add a billing rule that flags any dislocation code paired with 23700.
• Missing laterality modifier: Submitting CPT 23700 without -RT or -LT. Fix: Add laterality modifier validation to the charge entry workflow; treat it as a required field.
• Billing 23700 with excluded arthroscopy codes: Submitting 23700 and 29825 together without checking the NCCI edit or appending a valid modifier. Fix: Run an NCCI edit check on every claim pairing CPT Code 23700 with a 29xxx code.
• Global period violations: Billing a routine post-procedure E&M visit within the 10-day global period without a distinct modifier. Fix: Enter the global period end date at discharge and flag any E&M visit booked inside that window.

A clean claim on the first pass needs all six triggers resolved before transmission. Keep the operative report and PT records on file too, because a paid claim can still be audited later.

Documentation checklist for the operative report

Coders can hand this checklist to the surgeon before the operative report is signed. Each item answers a question a payer reviewer asks when a 23700 claim is pulled for review.

• Indication (primary diagnosis): Adhesive capsulitis or capsular contracture with specific laterality documented in the history
• Conservative treatment failure: Dates, frequency, and outcomes of prior physical therapy explicitly noted
• Anesthesia type: General or regional (e.g., interscalene block); documented by surgeon and anesthesiologist
• Patient positioning: Supine or lateral decubitus, shoulder positioning noted
• Pre-procedure ROM measurements: Forward flexion, abduction, external rotation, internal rotation with degree values
• Manipulation technique: Planes of force applied and the degrees reached in each (for example, forward flexion to a stated angle)
• Fixation apparatus (if applied): Type (sling, immobilizer), rationale, and post-op wear instructions
• Post-procedure ROM measurements: Same planes as pre-procedure, with improvement quantified
• Post-op plan: Physical therapy initiation date, pain management protocol, follow-up appointment
• Surgeon attestation: Operative report signed and dated by the performing surgeon

How claims management software reduces rework on 23700 claims

Orthopedic practices billing CPT 23700 hit the same pressure points on every case. There’s the authorization, the operative note, and the claim itself. When those sit in separate systems, a lapsed coverage check only surfaces as a denial weeks later.

Pabau keeps them on one patient record. Your front desk runs an eligibility check before the procedure day. After the procedure, the claim is pre-filled from details already on the record and submitted through Claim.MD.

Pabau flags missing claim details before submission, so avoidable rejections are caught at the desk. Claim status and ERA remittances post back against each claim. Your billing team sees what paid and what didn’t without chasing paper EOBs.

Take shoulder MUA claims from eligibility to payment

Pabau checks eligibility, submits claims through Claim.MD, and posts remittances against each claim. Your team spends less time on rework and more time on patient care.

Conclusion

Treat the operative report as the claim. Before a coder touches a 23700 case, check that it names the anesthesia type and carries ROM measurements from before and after the manipulation. Then put the 10-day global end date on the calendar.

Front-loading those checks costs a few minutes per case. A corrected claim or an appeal costs far more, and a dislocation diagnosis on the claim can’t be appealed into a payment at all.
