This Medical Charge & Necessity Review was prepared at the request of the defense / carrier to evaluate the claimed medical special damages on four dimensions — necessity, relatedness, physician-led coding-integrity screening, and charge reasonableness — and to apportion pre-existing pathology. The objective is a documented billed-charge exposure position: what is defensible, what is attributable to the collision, and how much of the billed total may not be supportable for reserve or payment on this record.
The review is a non-testifying, attorney-directed consulting work product. It is not a coverage opinion, not a legal damages valuation, and not expert testimony. Conclusions are physician-authored; record extraction and charge tabulation may be AI-assisted, with physician review of every conclusion.
A 53-year-old male was rear-ended at low speed (≈12 mph, minor property damage) and reported neck and low-back pain. Imaging showed no acute fracture or disc herniation — the findings are multilevel lumbar degeneration and facet arthropathy, consistent with a 2023 lumbar MRI predating the collision. The working injury is a cervical and lumbar soft-tissue sprain. Despite that, the claimant accrued 58 chiropractic visits, 26 concurrent physical-therapy visits, two lumbar facet-injection sessions, and multiple DME items over seven months. The clinical picture (uncomplicated low-speed strain) and the volume/character of the billed care are mismatched — which is what this review quantifies.
Line-item audit. “Reasonable value” is the defensible amount after necessity, coding, and reasonableness review. “Pre-existing” is the share of that reasonable value attributable to prior degenerative pathology (see Section 06). Codes are illustrative.

Unbundling: a 2–3 view cervical X-ray (72040) was billed on the same date as the complete cervical study (72052) of the same region — the limited study is included in the complete; billing both is unbundling, and 72040 is disallowed. Region overstatement: chiropractic manipulation billed at 98941 (3–4 regions) where the documented exam supports 98940 (1–2). Duplication: physical therapy billed manual-therapy and modality units overlapping the concurrent chiropractic care on the same dates and regions.
Necessity is assessed against criteria logic used in payer utilization review. The acute evaluation and early active care are supported; the dispute is the months of high-frequency passive care and the facet injections.
The records document functional improvement plateauing by roughly visit 12; the subsequent 40-plus visits repeat without measurable gain in range of motion, pain score, or function. Care continued past plateau is the standard payer trigger for a maintenance-care necessity denial. Visits to plateau are supported; the maintenance tail is not.
Lumbar facet (zygapophyseal) injections treat facet-mediated degenerative pain, not an acute ligamentous sprain. On a low-speed mechanism with no acute structural finding, the injections are weakly supported as accident-related and point instead to the pre-existing facet arthropathy documented on the 2023 imaging — carried into Section 06 as apportionment.
Reasonableness is assessed by line against a stated benchmark method: a licensed commercial charge-and-allowed-amount database (e.g., FAIR Health) by CPT/HCPCS and geozip, with the CMS Physician Fee Schedule (PFS/RBRVS) as a reference floor, each opinion expressed at a stated percentile (illustrative: 75th percentile, FAIR Health allowed-amount data, geozip 852XX for this specimen). For a carrier audience the allowed-amount benchmark is the operative figure, not the chargemaster.
Medicare ≠ chargemaster ≠ negotiated rate ≠ reasonable value. The provider’s billed amount, the Medicare allowable, a commercial negotiated/allowed rate, and the tort “reasonable value” are four different figures, and the governing measure of recoverable medical damages is jurisdiction-dependent. This review anchors to the allowed-amount and market percentile rather than the billed total, which is typically the more defensible reserve basis under cross-examination.
After the line-item necessity and coding reductions, the gross reasonable value is $12,700 of $36,740 billed — before apportionment.
A 2023 lumbar MRI predating the collision documents multilevel disc degeneration and facet arthropathy, with a prior history of intermittent low-back complaints. A share of the supported care treats that pre-existing condition rather than the collision, and is apportioned out of the accident-related figure.
The facet injections are apportioned predominantly to pre-existing facet arthropathy; portions of the chiropractic, physical-therapy, imaging, and pain-management lines reflect the chronic degenerative component. Applying line-level pre-existing fractions to the supported reasonable value yields $4,315 attributable to pre-existing pathology, leaving an accident-related reasonable value of $8,385.
Apportionment is a medical opinion on attribution, not a legal ruling. A claimant may argue the collision aggravated a quiescent degenerative condition; the counter is the pre-collision imaging and complaint history and the low-speed mechanism. The range below reflects this: accident-related value rises toward the gross figure if aggravation is credited, and falls toward the apportioned figure if it is not.
| Finding | Amount |
|---|---|
| Claimed medical specials (billed) | $36,740 |
| Reasonable value after line-item audit (gross) | $12,700 |
| Attributable to pre-existing pathology | − $4,315 |
| Accident-related reasonable value | $8,385 (range $8,385–$12,700) |
| Flagged exposure above accident-related value | $28,355 of $36,740 billed |
| Lines with an identified issue | 7 of 7 |
The acute injury is real but minor; the billed total is driven by months of post-plateau passive care, duplicative concurrent therapy, coding overstatement, and injections directed at pre-existing degeneration. Reserve and negotiation posture should be set to the accident-related range, with the pre-existing apportionment documented for the file.
Necessity was assessed against published utilization-review criteria logic (MCG / InterQual-style thresholds); coding against CPT/HCPCS rules and NCCI bundling logic; reasonableness against the data backbone named in Section 05 (a licensed commercial charge-and-allowed-amount database by CPT/HCPCS and geozip, with CMS PFS/RBRVS as a reference floor) at the stated percentile (75th, FAIR Health allowed-amount data by geozip); apportionment against the pre-collision imaging and complaint history.
Each reduction states the criterion, bundling rule, or benchmark it rests on and the record page that supports it, so the exposure figure is reproducible line by line rather than a global discount. The reviewing physician’s payer-side utilization-management background is the basis for the necessity and over-utilization opinions.
This review is limited to the records provided and the benchmark data available at engagement; it is non-testifying and is not a coverage or legal-damages determination. The apportionment is a medical attribution opinion expressed as a range, not a legal allocation.
If the matter proceeds to mediation or trial, the charge and necessity opinions should be carried by a retained testifying expert — a U.S.-credentialed coding/billing expert (CPC / CIC / CPMA) for the sworn billed-charge opinion and, on causation/apportionment, an appropriate physician specialist. This review supports a compulsory medical examination (CME/IME) and a records deposition of the high-volume providers, and Medisprudence can prepare those examiners; it does not itself provide the testimony or affidavit.
