Why CPT codes matter in PI cases
CPT (Current Procedural Terminology) codes describe every medical service billed — from an office visit to a spinal fusion. In personal injury, these codes determine the dollar value of your specials (total medical charges) and are the primary target of defense billing audits.
Specials valuation: Every CPT code maps to a billed charge. Defense experts review each code for medical necessity, correct level selection, and appropriate frequency. One upcoded ER visit can undermine credibility on the entire demand.
Level selection disputes: E&M codes (99202-99215) are the most commonly disputed. Defense compares the billed level against documented history, exam, and medical decision-making. Over-coding by one level on every visit adds up fast.
Imaging justification: MRI codes require clinical justification. Defense argues that degenerative findings on MRI are age-related, not traumatic. The CPT code alone does not resolve this — but knowing what was billed helps you anticipate the challenge.
PT volume challenges: Physical therapy codes (97110, 97140) are billed per 15-minute unit. Defense disputes both the number of units per visit and the total visit count. Excessive PT without objective improvement is a red flag.

Common billing red flags
Upcoded E&M levels
Every visit billed at 99215 (highest follow-up) when records show routine check-ins. Defense will average levels across all visits.
Excessive PT units
More than 4-6 units of therapy per visit (60-90 minutes) without documented medical necessity. Defense expects objective functional gains.
Duplicate imaging
Multiple MRIs of the same body part without new symptoms or treatment changes. Defense argues the second scan was not medically necessary.
Unbundled procedures
Billing separately for components that should be included in a single code. Defense uses NCCI edits to identify bundled codes.
FAQ
Frequently Asked Questions
What is a CPT code?
CPT (Current Procedural Terminology) codes are 5-digit numbers that describe every medical service, procedure, or test performed. They are used by providers for billing and by insurers for reimbursement. Every line item on a medical bill has a CPT code.
What is the difference between CPT and ICD-10 codes?
ICD-10 codes describe the diagnosis (what is wrong with the patient). CPT codes describe the procedure or service (what was done). A claim needs both — the ICD-10 justifies why the service was performed, and the CPT describes what was performed.
How do CPT codes affect my PI case?
CPT codes determine the dollar value of your specials (total medical charges). Defense experts review CPT codes for medical necessity, correct level selection, and frequency. Understanding what was billed helps you anticipate defense challenges and evaluate whether your specials are defensible.
What does the cost range represent?
Cost ranges reflect typical billed charges for each code. Actual amounts vary by provider, facility, and region. Use these ranges as a reference point — if a provider is billing significantly above or below the range, it may warrant investigation.
How accurate are the dispute notes?
The dispute notes reflect common defense strategies used in personal injury litigation. They are based on typical billing audit patterns and case law trends. Specific challenges will vary by jurisdiction, defense firm, and case facts.
Why are physical therapy codes billed per 15-minute unit?
CPT therapy codes (97110, 97140, 97530, etc.) are timed codes billed in 15-minute units. A 45-minute session of therapeutic exercise = 3 units of 97110. Defense scrutinizes whether the total units are supported by documentation and whether the time was spent on direct, one-on-one treatment.
