Physical Therapy Practices Industry Terminology

ABN (Advance Beneficiary Notice)

A Medicare-specific form used to notify beneficiaries that a service may not be covered and that the patient agrees to pay if Medicare denies it. It documents informed financial consent and must be presented before the noncovered service is provided.

- At the evaluation we issued an ABN because Medicare is unlikely to cover maintenance dry needling. - Be sure the ABN is specific to the service and signed before treatment begins. - We didn’t need an ABN for this patient because they have commercial insurance, not Medicare.

Accounts Receivable (AR) Days

A metric indicating the average number of days it takes to collect payment after a service is rendered. Calculated as total AR divided by average daily charges; lower is better for cash flow.

- Our AR days dropped from 45 to 28 after we tightened verification and coding. - Benchmark AR days below 35 for a healthy PT revenue cycle. - Rising AR days signaled delays with our clearinghouse submissions.

Anti-Kickback Statute (AKS)

A federal law prohibiting offering, paying, soliciting, or receiving remuneration to induce referrals for services reimbursed by federal healthcare programs. Violations carry criminal and civil penalties.

- Waiving copays routinely for a referring physician’s patients could trigger AKS concerns. - Our marketing arrangement was reviewed to ensure fair market value and AKS compliance. - The compliance officer trains staff annually on AKS and Stark differences.

Authorization (Prior Authorization)

Payer pre-approval for a specified number of visits or time period. Often required for certain diagnoses or plans and tied to utilization management rules.

- eviCore approved 8 PT visits; we must request additional auth after the progress note. - The front desk flags plans that require authorization before scheduling the IE. - Denial overturned on appeal due to missing authorization reference number on the claim.

Balance Training

Interventions aimed at improving postural control and reducing fall risk, often using static and dynamic tasks; frequently billed under neuromuscular re-education (97112) or therapeutic activity (97530) depending on intent.

- We billed neuromuscular re-education for dynamic balance drills on foam. - The plan of care includes balance progression from static to dual-task activities. - Falls risk improved per BERG after four weeks of balance training.

Business Associate Agreement (BAA)

A HIPAA-required contract between a covered entity and a vendor that handles PHI, outlining permitted uses, safeguards, and breach responsibilities.

- We executed BAAs with our EMR vendor and billing company. - The cloud fax service provided a HIPAA-compliant BAA. - No PHI can be shared with a vendor until a BAA is in place.

Bundled Payment

A single payment for an episode of care across providers and settings (e.g., joint replacement), incentivizing coordination, quality, and cost control.

- Our clinic participates in the TKA bundle by meeting post-op rehab milestones. - Under the bundle, unnecessary visits reduce the episode margin for the convener. - We align our outcomes and costs to be attractive partners for bundled programs.

CAQH (Council for Affordable Quality Healthcare)

A centralized, standardized data repository used by payers for credentialing and contracting, reducing redundant paperwork for providers.

- Update your CAQH profile every 120 days to avoid credentialing delays. - The payer pulled our data from CAQH ProView during enrollment. - Missing license upload in CAQH stalled our Blue Cross contracting.

Cash-Based Practice

A PT business model where patients pay directly for services, often outside insurance networks, emphasizing transparent pricing, value, and patient experience.

- We issue a superbill so out-of-network patients can seek reimbursement. - Transparent price bundles boosted our cash-pay conversions. - Our cancellation policy is stricter for cash-based visits.

Clearinghouse

An intermediary that scrubs, formats, and transmits electronic claims and remittances between providers and payers, reducing errors and speeding adjudication.

- Our claims are sent as 837P files through the clearinghouse. - The clearinghouse rejection showed a missing GP modifier. - We automated ERAs from the clearinghouse into our EMR.

Coinsurance

A cost-sharing percentage the patient pays for covered services after the deductible is met. Unlike a copay, it varies with the allowed amount.

- This plan has 20% coinsurance after deductible is met. - Our estimate shows approximate coinsurance of $18 per visit. - Failure to collect coinsurance increases bad debt risk.

Copay

A fixed dollar amount the patient pays at the time of service for covered care, set by the insurance plan.

- The patient owes a $35 copay at each PT visit. - Copays apply even when the deductible is met for this plan. - We offer contactless copay collection at check-in.

CPT Codes (Current Procedural Terminology)

Standardized procedure codes used to describe and bill healthcare services. PT staples include 97110, 97112, 97116, 97140, 97530, 97032, 97035, etc.; some are timed and some untimed.

- We billed 97110 (therapeutic exercise) for 2 units and 97140 (manual therapy) for 1 unit. - Medicare requires the GP modifier on therapy CPT codes. - Ensure documentation supports CPT code selection and units.

CQ/CO Modifiers (PTA/OTA Services)

Medicare modifiers appended when PTAs (CQ) or OTAs (CO) furnish services beyond the de minimis threshold, triggering reduced payment (15% differential) for those services.

- Add CQ when a PTA furnishes more than the de minimis portion of a timed code for Medicare Part B. - Claims with CQ receive the PTA differential reduction. - CO applies similarly for OTAs in occupational therapy.

Credentialing

The process of verifying a clinician’s qualifications and enrolling the clinic with payers to obtain in-network status and contracted rates.

- Expect 60–180 days for payer credentialing and contracting. - We tracked credentialing tasks in a shared checklist by payer. - Lacking credentialing forced us to bill out-of-network initially.

Deductible

The amount a patient must pay out of pocket for covered services before insurance begins paying, usually on a calendar-year basis.

- The patient has a $1,500 deductible; early visits will be patient-pay. - Our estimate tool shows remaining deductible and expected costs. - After meeting the deductible, only coinsurance applies.

Direct Access

The legal ability for patients to see a PT without a physician referral, with state-specific limits on duration, diagnosis, or interventions.

- State law allows 30 days of direct access before a physician referral is required. - Medicare still requires plan-of-care certification even with direct access. - Our marketing emphasizes convenient direct access appointments.

Documentation Compliance

Ensuring records are accurate, complete, support medical necessity, and meet payer and regulatory requirements (e.g., time/units, goals, signatures, progress reports).

- SOAP notes must support medical necessity and chosen CPT codes. - Progress reports every 10 treatment days meet Medicare standards. - Sign and date the plan-of-care to obtain timely certification.

Dry Needling

A skilled intramuscular technique using filiform needles to treat neuromusculoskeletal pain and dysfunction. Billing uses 20560/20561 for many payers; coverage and legality vary by state and payer.

- We used 20560 for needle insertion without electrical stimulation to multiple muscles. - Check state practice act before offering dry needling. - Many payers consider dry needling non-covered; discuss cash options.

EHR/EMR (Electronic Health/Medical Record)

Digital systems for clinical documentation, scheduling, billing, and reporting. Key for compliance, data security, and operational efficiency.

- Templates ensure the 8-minute rule and total treatment time are captured. - We integrated ERAs so payments auto-post in the EMR. - Role-based access controls protect PHI in the system.

Eight-Minute Rule

Medicare’s rule for timed CPT codes: at least 8 minutes of a code (or total pooled minutes) are required for 1 unit, with thresholds every additional 15-minute increment.

- 23 minutes of 97110 equals 1 unit; 24 minutes qualifies for 2 units. - Total timed minutes across all codes determine units for Medicare. - Some commercial plans follow AMA time rules; verify payer policy.

ERA/EOB (Electronic Remittance Advice/Explanation of Benefits)

Payer remittance documents detailing payment, adjustments, denials, and patient responsibility. ERAs are electronic versions that allow automated posting.

- The ERA shows CO-45 adjustments and patient responsibility. - Our team reconciles ERAs daily to speed secondary billing. - The EOB indicated a bundling denial due to NCCI edits.

Episode of Care

A time-bound set of services related to a specific condition or procedure, used in clinical planning and alternative payment models.

- We track outcomes across the post-op shoulder episode, not just single visits. - Bundled contracts define quality metrics for the entire episode. - Scheduling templates support the episode’s frequency and duration targets.

Evidence-Based Practice (EBP)

Clinical decision-making that integrates best research evidence, clinician expertise, and patient values to deliver effective, efficient care.

- We used the APTA CPG to guide manual therapy dosing for neck pain. - The HEP progressed based on MCID changes on the NDI. - Our protocols blend research, clinical expertise, and patient goals.

FCE (Functional Capacity Evaluation)

A standardized assessment of physical abilities and work tolerances, often used for workers’ compensation or disability determinations.

- The FCE ran 3 hours and was billed with 97750 units. - Worker’s comp requested an FCE to determine return-to-work readiness. - The report included safe lifting limits and positional tolerances.

Fee Schedule

A payer’s allowed amounts for each CPT code. Drives revenue projections, contracting strategy, and pricing.

- Our 2025 Medicare fee schedule cut manual therapy by 2%. - We renegotiated the Blue plan’s fee schedule based on regional benchmarks. - Cash rates should be set with reference to, not equal to, contracted fees.

FOTO (Focus on Therapeutic Outcomes)

A widely used patient-reported outcomes platform for rehab that provides risk-adjusted functional scores and benchmarking.

- FOTO risk-adjusted scores supported our value-based contract. - Patients complete FOTO at intake and discharge to quantify change. - We built therapist benchmarks from FOTO functional status data.

Gait Training (97116)

Skilled training to improve safe, efficient ambulation and device use; a timed code focused on functional walking tasks and safety.

- We billed 97116 for cane training on varied surfaces. - Documentation highlighted safety and independence goals for ambulation. - We separated 97116 from therapeutic exercise by intent and activity.

GP Modifier

A modifier indicating services furnished under a physical therapy plan of care; required by Medicare (and some commercial payers) on therapy codes.

- Append GP to all PT therapy services for Medicare Part B. - The claim denied because GP was missing on ultrasound. - Some commercial plans also require GP on therapy claims.

HEP (Home Exercise Program)

A personalized set of exercises patients perform outside the clinic to reinforce gains and accelerate recovery; critical for outcomes.

- We assigned HEP through a patient app to improve adherence. - HEP dosage progressed from isometrics to eccentric loading. - Nonadherence with HEP was addressed using motivational strategies.

HIPAA (Health Insurance Portability and Accountability Act)

U.S. regulations that set standards for privacy, security, and transactions of protected health information (PHI). Requires policies, safeguards, and BAAs.

- We conduct annual HIPAA training and phishing simulations. - A BAA with our texting platform ensures HIPAA-compliant reminders. - Breach protocols were followed after a misdirected fax.

ICD-10-CM

The diagnostic coding system used to describe patient conditions for billing and analytics; specificity affects medical necessity and authorization.

- Use M25.561 for right knee pain as the primary diagnosis when appropriate. - We added Z codes to capture social determinants affecting attendance. - Avoid unspecified codes when a more specific ICD-10-CM is supported.

Initial Evaluation (97161–97163) and Re-evaluation (97164)

PT evaluation codes stratified by complexity and a separate re-evaluation code used when a formal reassessment and plan update are warranted.

- Complexity level 97162 was supported by comorbidities and clinical presentation. - 97164 documented objective change and updated the plan of care. - Do not bill treatment codes without an established evaluation/POC.

Insurance Verification (VOB)

The front-end process of confirming benefits, coverage, cost-sharing, limitations, and authorization rules before care begins to prevent denials and surprises.

- We verified PT-specific benefits, visit limits, and pre-auth requirements. - The VOB revealed a $1,000 deductible still outstanding. - Document the reference number and representative name for each VOB.

Iontophoresis (97033)

A modality that delivers medication transdermally using low electrical current. Coverage varies; billed as a constant attendance, timed code.

- Dexamethasone iontophoresis was used for lateral epicondylalgia. - Many plans consider ionto experimental; verify coverage first. - We used 97033 as a timed code with appropriate documentation.

Joint Mobilization

Skilled passive movements applied to joints to improve mobility and reduce pain; commonly documented by technique and grade.

- We applied Maitland grade III mobilizations to improve shoulder elevation. - Mobilization was billed under manual therapy 97140. - The patient’s pain decreased after posterior hip joint mobilization.

KX Modifier

A modifier indicating that therapy services exceeding the annual Medicare threshold remain medically necessary and are supported by documentation.

- Add KX once the patient exceeds the annual therapy threshold. - Documentation must clearly support medical necessity when KX is used. - Claims without KX over the threshold will deny.

LEFS (Lower Extremity Functional Scale)

A 20-item patient-reported outcome measure for lower extremity function (0–80); commonly used to track progress and support medical necessity.

- LEFS improved from 38 to 58, exceeding the MCID. - We use LEFS at eval and discharge for knee and hip cases. - Payer required functional scales like LEFS for authorization.

Licensure Compact (PT Compact)

An agreement among participating states allowing PTs and PTAs to practice across state lines with a privilege, streamlining multi-state practice.

- The PT Compact privilege allowed us to treat telehealth patients across state lines. - We verified both home and distant state Compact participation. - Compact privileges renew separately from state licenses.

Letter of Protection (LOP)

An agreement in personal injury cases where the provider defers collection until legal settlement, assuming higher collection risk.

- We accepted an LOP for a motor vehicle accident case. - LOP balances were tracked separately due to payment risk. - The attorney negotiated final payment upon case settlement.

Manual Therapy (97140)

Skilled hands-on techniques to mobilize joints and soft tissues, reduce pain, and improve function; a timed code requiring clear intent and area treated.

- Soft tissue mobilization and joint mobilization were documented under 97140. - We avoided overlapping time with therapeutic exercise units. - Distinct anatomical regions justified separate billing with other codes.

Medicare MPPR (Multiple Procedure Payment Reduction)

A Medicare policy that reduces payment for the practice expense portion of additional therapy services billed on the same date, lowering total reimbursement.

- MPPR reduced payment on the second and subsequent therapy units. - We modeled revenue per visit including MPPR impacts. - Staggering code mixes sometimes mitigates MPPR effects.

MIPS (Merit-based Incentive Payment System)

A CMS program that adjusts Part B payments based on performance in quality and other categories; PTs have been eligible since 2019 under certain criteria.

- We reported PT-eligible quality measures to avoid a negative MIPS adjustment. - FOTO data supported our MIPS quality submissions. - Small practices may qualify for low-volume exemptions; verify annually.

Modifier 59 and X Modifiers (XE, XS, XP, XU)

Modifiers used to identify distinct procedural services and appropriately bypass NCCI bundling edits when clinically and procedurally separate.

- We added 59 to 97140 to bypass an NCCI edit with 97110 when truly distinct. - XS was used to denote a different anatomical site for manual therapy. - Never use 59 to unbundle services without proper documentation.

Modalities: Timed vs Untimed

Some modality codes require one-on-one, time-based billing (e.g., 97032, 97035), while others are service-based and untimed (e.g., 97012, G0283 for Medicare).

- Ultrasound (97035) is timed; unattended e-stim is G0283 for Medicare and untimed. - Traction (97012) is untimed; attended e-stim (97032) is timed. - Total treatment time must reflect all timed modalities accurately.

NCCI Edits (National Correct Coding Initiative)

CMS coding rules that define which CPT code pairs are typically bundled and not separately payable unless distinct criteria are met.

- 97530 and 97110 often hit NCCI edits; use correct intent and, if distinct, modifier 59. - Our denial cited NCCI; we clarified separate, sequential services and appealed. - Review quarterly NCCI updates to maintain compliance.

NPI (National Provider Identifier)

A unique 10-digit identifier for healthcare providers and organizations used in standard transactions and billing.

- Claims use the clinician’s Type 1 NPI and the clinic’s Type 2 NPI. - Our clearinghouse flagged a mismatch between NPI and taxonomy. - Keep NPIs updated in CAQH and with payers after address changes.

No-Show Rate

The percentage of scheduled appointments that patients miss without adequate notice; a key KPI affecting productivity and patient outcomes.

- We reduced no-show rate from 12% to 5% with reminder texts and waitlists. - Therapists review schedules daily to fill likely no-shows. - High no-show rates depress units per visit and revenue.

Oswestry Disability Index (ODI)

A validated, low back pain–specific patient-reported outcome measure (0–100% disability) used to track function and medical necessity.

- ODI improved from 46% to 26%, exceeding the MCID. - We use ODI for lumbar patients alongside pain scales. - Payers accepted ODI changes as evidence of functional progress.

Plan of Care (POC) and Certification

A formal statement of goals, frequency, duration, and interventions created by the PT. Many payers, including Medicare, require physician or NPP certification and periodic recertification to continue care.

- The POC outlined frequency 2x/week for 6 weeks with functional goals. - Medicare requires timely physician/NPP certification and periodic recertification (e.g., every 90 days). - We sent the POC electronically for signature within 24 hours of the IE.
