Coverage Summary

Scope summary: UnitedHealthcare Community Plan medical policy CS075KS.02 (Effective March 1, 2026) governs Manipulation Under Anesthesia (MUA) for members in Kansas, specifying covered and not-covered indications for this procedure.

Summary of covered indications: MUA is considered medically necessary for the knee joint to treat arthrofibrosis following total knee arthroplasty (TKA), knee surgery, or fracture, and for the shoulder joint to treat adhesive capsulitis (frozen shoulder) when the member meets the InterQual CP: Procedures, Manipulation Under Anesthesia, Shoulder clinical criteria.

Medical-Necessity Criteria

Medically Necessary

Manipulation under anesthesia is proven and medically necessary when the following specific joint/condition criteria are met:

ANY of the following

Knee joint for Arthrofibrosis following total knee arthroplasty, knee surgery, or fracture
Shoulder joint for adhesive capsulitis (frozen shoulder) when INTEGRAL InterQual CP: Procedures, Manipulation Under Anesthesia, Shoulder clinical criteria are met
Refer to InterQual CP for medical necessity clinical coverage criteria

Not Medically Necessary / Unproven

Manipulation under anesthesia is unproven and not medically necessary for all other conditions (single or serial manipulations) due to insufficient evidence of efficacy, including but not limited to:

ALL of the following

Ankle
Finger
Hip joint or adhesive capsulitis of the hip
Knee joint - any condition other than Arthrofibrosis following total knee arthroplasty, knee surgery, or fracture
Pelvis
Spine
Temporomandibular joint
Toe
Wrist

Exclusions / Not Applicable

This policy does not apply to the following procedures:

ALL of the following

Manipulation of the finger on the day following the injection of collagenase clostridium histolyticum (Xiaflex) to treat Dupuytren contracture
Closed reduction of a fracture or joint dislocation unless specified
Elbow joint for Arthrofibrosis following elbow surgery or fracture

Provider Actions & Billing Guidance

Documentation Required

Use InterQual criteria for shoulder MUA coverage determination

For shoulder adhesive capsulitis, document that the member meets InterQual CP: Procedures, Manipulation Under Anesthesia, Shoulder clinical criteria; coverage is dependent on meeting those criteria.

Background, Evidence & Definitions

Manipulation under anesthesia (MUA) is a noninvasive procedure that combines manual manipulation of a joint or the spine with an anesthetic to permit breaking adhesions and improving range of motion for individuals who cannot tolerate awake manual procedures (e.g., due to pain, spasm, or guarding).

Supported indications: Evidence in the policy supports MUA as medically necessary for the knee to treat arthrofibrosis after total knee arthroplasty, knee surgery, or fracture, with multiple systematic reviews, studies, and a randomized trial demonstrating clinically meaningful range-of-motion gains and treatment effect in this setting. For the shoulder, MUA is considered medically necessary for adhesive capsulitis (frozen shoulder) only when the member meets the InterQual CP clinical criteria referenced in the policy.

Insufficient evidence for other joints: The policy states MUA is unproven and not medically necessary for many other joints and conditions (including spine and temporomandibular joint), noting the literature for these sites is limited by small sample sizes, lack of high-quality controlled studies, inconsistent results, and inadequate long-term safety/effectiveness data.

Evidence Type	Summary
Randomized trial (Abdel et al. 2024)
Multicenter randomized trial (n=124) of MUA after TKA found immediate mean ROM improvement of 46° (from 72° to 118°) after MUA; ROM at 6 weeks and 1 year similar between groups randomized to anti-inflammatory adjuvants vs control.
Systematic review/meta-analysis (Patel et al. 2025)
Systematic review and meta-analysis identifying risk factors for requiring MUA after primary TKA (younger age, Black race, smoking, lower ASA score, prior knee procedure) based on 53 studies (2,931,517 individuals).
Multiple systematic reviews (Haffar 2022; Gu 2018; Hopper 2024; Akhtar 2024)
Systematic reviews/meta-analyses support efficacy of MUA for postoperative knee arthrofibrosis with reported mean ROM gains (eg, ~21° average increase after MUA in Haffar; consistent post-TKA ROM improvements in Gu; early vs delayed MUA shows greater mean flexion gain with early MUA per Akhtar; Hopper identifies risk factors after ACLR).
Descriptive/Mechanistic (Reid & Desimone 2002)
Policy description: MUA is a noninvasive procedure combining manual manipulation with anesthesia to break adhesions and improve ROM; theoretical rationale and typical anesthetic approaches described.
Case series / observational (TMJ, toe studies)
Smaller observational studies report variable and sometimes transient improvements for TMJ and first MTP joint MUA; evidence limited by small size and lack of controls.

Arthrofibrosis: A complication of injury or trauma in which an excessive scar tissue response leads to painful restriction of joint motion, with scar tissue forming within the joint and surrounding soft tissue spaces and persisting despite rehabilitation exercises and stretches (International Pain Foundation).
