How to Appeal a UnitedHealthcare Physical Therapy Denial

You've just received another denial letter from UnitedHealthcare for physical therapy services, and the frustration is setting in. Your patient clearly needed those CPT 97110 therapeutic exercise sessions, yet UnitedHealthcare has denied payment citing vague reasons about medical necessity or visit limits. CPT 97110 is therapeutic exercise, billed in 15-minute units. An appeal has to answer the specific reason in the denial, whether a visit limit, medical necessity or documented progress, with the records for the dates of service.

Why UnitedHealthcare Denies Physical Therapy

Denials of CPT 97110 usually come from one of three areas.

Visit Limit Exceeded Without Prior Authorization
Visit limits for outpatient therapy come from the member's benefit plan, and many plans require prior authorization or a progress review before additional visits. Check the member's benefits and the plan's current therapy policy for the limit and for whether authorization is needed to continue. Claims for visits beyond an authorized number are typically denied automatically, whatever the patient's clinical progress, so ask whether the plan will accept a retroactive or new authorization request, and send objective progress measurements with it.

Insufficient Medical Necessity Documentation
Therapy policies generally ask for evidence that CPT 97110 services address functional limitations that significantly affect the patient's activities of daily living or work. Generic notes such as patient performed exercises or tolerated treatment well do not show that. Document quantifiable functional deficits, the specific exercises and parameters, why the skills of a therapist were needed, and how the interventions relate to the diagnosed condition. Check the plan's current therapy policy for the elements it requires.

Progress Not Adequately Documented
Commercial therapy policies commonly expect measurable progress toward specific goals for continued rehabilitative therapy: objective changes in range of motion, strength, pain scales and functional capacity. When progress notes do not show that, continued CPT 97110 services are often denied, so check the plan's current policy for how it treats maintenance therapy. Medicare is different: coverage of skilled therapy does not depend on the patient improving, and under the Jimmo v. Sebelius settlement (2013) maintenance therapy is covered when it needs the skills of a therapist. Medicare Advantage plans must follow traditional Medicare's general coverage and benefit conditions (42 CFR 422.101(b)), so for a UnitedHealthcare Medicare Advantage member, a denial that rests only on a lack of improvement is worth challenging on that basis.

What You Need to Win This Appeal

Successfully overturning a UnitedHealthcare physical therapy denial requires assembling comprehensive clinical documentation that directly addresses their specific review criteria. Your appeal package must demonstrate both medical necessity and appropriate clinical progression through concrete evidence.

Complete Initial Evaluation and Plan of Care
Your appeal must include the comprehensive initial physical therapy evaluation that established baseline functional measurements. Include objective documentation of range of motion limitations, strength deficits (measured via manual muscle testing or dynamometry), pain levels using standardized scales, and functional limitations that impact activities of daily living or work activities. The initial plan of care should specify measurable short-term and long-term goals with projected timeframes for achievement.

Objective Progress Documentation
Compile all progress notes that demonstrate quantifiable improvements in the patient's functional status. Reviewers expect to see advancing measurements in areas such as range of motion degrees, strength grades, pain scale improvements, and functional capacity enhancements. Include any standardized outcome measures utilized, such as the Oswestry Disability Index for back pain or the DASH questionnaire for upper extremity conditions. Validated tools give the reviewer a standard measure to check.

Physician Orders and Supporting Medical Records
Include all physician referrals, prescription orders for physical therapy, and relevant medical records that support the need for therapeutic exercise interventions. Include any signed plan-of-care certification or referral the plan requires, and any changes to the therapy prescription based on patient progress. If the denial involves exceeding visit limits, include physician documentation supporting the need for continued care beyond the initial authorization period.

Clinical Guidelines Correlation
Reference relevant clinical practice guidelines that support the use of therapeutic exercise for the patient's specific diagnosis. The American Physical Therapy Association's clinical practice guidelines, specialty society recommendations, and evidence-based treatment protocols help establish medical necessity. Cite the specific guideline and recommendation, not the guideline in general.

Step-by-Step: Appealing Your UnitedHealthcare Physical Therapy Denial

UnitedHealthcare maintains specific procedural requirements for physical therapy appeals that must be followed precisely to avoid additional delays or automatic rejections.

File Within Required Timeframes
There is no single UnitedHealthcare deadline. UnitedHealthcare's provider appeals page says that, except where law prohibits it, a provider who disagrees with a claim determination must first request a claim reconsideration and can then file a post-service appeal, with 12 months to complete both steps; its FAQ also says timelines vary and refers providers to their participation agreement (UHCprovider.com). Check the contract and the denial notice. For a prior authorization denial, the same page says a pre-service appeal should be made before the planned service. When the member appeals, or the practice appeals as the member's authorized representative, an ACA-compliant commercial or employer group plan must allow at least 180 days from the adverse benefit determination, and after a final internal denial the member can request external review within 4 months under the federal process (state processes vary). A Medicare Advantage member has 65 days from the date of the notice to request reconsideration, and Medicaid windows vary by state and plan. Put the date on the calendar the day the denial arrives.

Submit to Correct Address and Include Required Information
Most network providers must submit reconsiderations and appeals digitally, through the UnitedHealthcare Provider Portal or an API, according to UnitedHealthcare's appeals page (UHCprovider.com); otherwise, use the address named in the denial notice. Include the member's ID number, dates of service, claim numbers and provider NPI, and say whether the submission is a claim reconsideration or an appeal, because that page describes a reconsideration first and an appeal second for a disputed claim determination. Put the identifiers on every page so attachments cannot be separated from the appeal.

Structure Your Appeal Letter Strategically
Begin your appeal letter with a clear statement of the services being appealed and the specific denial reason you're addressing. Organize your clinical argument logically, starting with medical necessity justification, followed by progress documentation, and concluding with policy compliance evidence. Use bullet points and headers to make your appeal easy for reviewers to navigate quickly.

Request Peer-to-Peer Review When Appropriate
For complex cases or high-value denials, request a peer-to-peer review with UnitedHealthcare's medical director. This option allows the treating physical therapist to discuss the case directly with the reviewing physician, providing opportunity to clarify clinical reasoning and address specific concerns. UnitedHealthcare's appeals page says peer-to-peer review applies to prior authorizations UnitedHealthcare manages itself (not those handled by third-party vendors), can be done before an appeal is submitted, and must be requested within a short time after the denial (UHCprovider.com), so ask as soon as the denial arrives.

Sample Appeal Arguments for Physical Therapy Denials

Crafting compelling clinical arguments requires connecting your patient's specific clinical presentation to UnitedHealthcare's medical necessity criteria using language that resonates with their review process.

Functional Limitation Argument for Medical Necessity
"The patient presents with significant functional limitations impacting activities of daily living, as evidenced by inability to reach overhead (shoulder flexion limited to 90 degrees) preventing performance of essential self-care activities. CPT 97110 therapeutic exercise interventions specifically target these functional deficits through progressive range of motion and strengthening exercises designed to restore overhead reaching capacity. [Plan policy name and number] covers therapeutic exercise when [quote the criterion], which this record meets."

Measurable Progress Documentation
"Objective measurements demonstrate clinically significant improvement throughout the treatment episode. Initial evaluation revealed 4/5 hip abductor strength with positive Trendelenburg gait pattern. Following CPT 97110 therapeutic exercise interventions, repeat testing shows 4+/5 strength with resolution of gait deviation, representing meaningful functional progress. Pain levels decreased from 7/10 to 3/10 on numerical rating scale, with corresponding improvement in walking tolerance from 2 blocks to 6 blocks without assistive device. This documented progress meets [plan policy name and number, criterion for continued care]."

Clinical Guidelines Compliance
"Treatment approach aligns with established clinical practice guidelines for this diagnosis. [Name the APTA or other clinical practice guideline for this diagnosis] recommends therapeutic exercise for this condition ([quote the recommendation and its evidence grade]). The prescribed exercise program targets the impairments identified at evaluation, consistent with that recommendation."

Visit Limit Justification
"While the patient has received the initially authorized number of visits, continued CPT 97110 services remain medically necessary due to ongoing functional deficits that impact work-related activities. The patient's job requires lifting 50 pounds regularly, yet current functional capacity testing reveals only 30-pound lifting tolerance. Continued therapeutic exercise is required to achieve full functional restoration and prevent re-injury. [If the plan's benefits or policy allow additional visits, cite that provision here.]"

Re: Request for [claim reconsideration or appeal] for [patient name], member ID [member ID], claim number [claim number], dates of service [dates of service], CPT 97110 [and any other codes billed]

To the appeals reviewer:

On behalf of [treating therapist name], we request [reconsideration or appeal] of the denial dated [denial date] of the physical therapy listed above. The denial states [denial reason and code, as written in the denial letter]. The enclosed records show the services were medically necessary. Please reverse the denial and process the claim.

The patient was evaluated on [date] for [diagnosis], with limitations in [daily activities or work tasks] and baseline [range of motion, strength, pain and outcome scores, such as Oswestry or DASH]. The plan of care set measurable goals of [goals and dates]. Therapeutic exercise, [exercises and parameters], required a therapist's skills because [reason]. By [date], the patient measured [current values], and [remaining deficit] still limits [activity].

[If denied for the visit limit:] The patient has used [number] of [number] authorized visits. Continued care is needed for [remaining deficit], and we request [a new or retroactive authorization] if the plan allows it.

[If a Medicare Advantage plan denied for lack of improvement alone:] Medicare coverage of skilled therapy does not depend on the patient improving, and Medicare Advantage plans must follow traditional Medicare's general coverage and benefit conditions (42 CFR 422.101(b)).

The denial relies on [policy name and number, if the denial cites one]. That policy covers therapeutic exercise when [quote the criterion], and the enclosed records meet it on [page references].

Enclosures:

• Denial letter dated [date]
• Initial evaluation and plan of care
• Progress notes with objective measures and outcome scores
• Treatment notes for the dates of service
• Physician referral, orders and any signed plan-of-care certification
