What the 52 Modifier Means on NEMT Claims: Minnesota, Nebraska, and New Jersey

Updated October 6, 20265 min read

Overview

The 52 modifier means reduced services in CPT, but NEMT payers give it their own meanings. As of October 2026, South Country Health Alliance in Minnesota marks no-shows with 52, Nebraska Medicaid marks T2003 trips that are not wholly inside Lincoln or Omaha, and New Jersey's disability division marks a self-directed employee's ride time. Add 52 only when your payer's schedule names it for that code.

In CPT the 52 modifier means reduced services. No national rule gives it a ride meaning, so each NEMT payer defines it.
South Country Health Alliance in Minnesota wants 52 on a no-show line with no mileage, and only contracted companies are paid for no-shows.
Nebraska fee-for-service pays T2003 with 52 at $9.41 for trips not wholly within Lincoln or Omaha, against $19.69 for a trip inside the city limits.
New Jersey's disability division bills a self-directed employee's transportation as A0090HI52, per 15 minutes, at a negotiated rate.
A state can deny or reject a line that carries a modifier it did not ask for, so never add 52 to lower or reshape a claim on your own.

What the 52 modifier means in standard billing

In CPT, the physician code set the AMA publishes, modifier 52 means reduced services. CMS’s Medicare Claims Processing Manual (Chapter 4, Rev. 13799, May 28, 2026), in its rules for hospital outpatient claims, says it indicates “partial reduction, cancellation, or discontinuation of services for which anesthesia is not planned,” a way to report reduced services “without disturbing the identification of the basic service.” CMS’s Medicaid NCCI manual (revision date January 1, 2026) uses it the same way, for a test done with an endoscopy where “a reduced level of service was performed.”

None of that describes a ride. NEMT codes such as T2003 and A0130 are HCPCS Level II codes, not CPT (see HCPCS vs CPT), and each payer decides which modifiers it wants on them. As of October 2026, these three payers give 52 three unrelated jobs.

The same Medicaid manual warns that states may deny or reject claim lines on which a modifier is inappropriately appended to a code. That is why a 52 you add without the payer’s say-so can cost you the line.

Minnesota: 52 marks a no-show at South Country Health Alliance

South Country Health Alliance, a Minnesota health plan, arranges rides through its RideConnect program. Its provider manual (Chapter 27, last updated February 27, 2026) defines a no-show as a scheduled ride that was not cancelled, where the driver arrives at the pickup and the rider is not there. For each ride type, the manual lists a no-show line that requires modifier 52 and pays no mileage:

Ride type	No-show line in the manual
Unassisted (taxi)	A0100 with 52
Ambulatory	T2003 with 52
Protected	T2003 with 52
Stretcher	T2049 with 52
Wheelchair	S0209 with 52

The stretcher and wheelchair lines use T2049 and S0209, the codes the manual uses for loaded miles on those rides, where the pickup codes are T2005 and A0130. South Country’s no-show example sheet, which the manual links from these rows, lists the same no-show lines. It bills the no-show as 1 unit, says to enter no mileage and no other code, and says it applies only to contracted providers.

You must report every no-show to RideConnect by secure email with the member’s name, ID number, and the date, and the manual says you must document all activity connected to it. Only contracted providers are paid for no-shows; non-contracted providers are not. Questions go to RideConnect at 1-866-567-7242. See South Country Health Alliance for the rest of its rules.

Do not carry this to other Minnesota payers. MTM Health’s Minnesota provider page says it does not reimburse transportation providers for no-shows, so no code, 52 or otherwise, gets one paid there. For how no-shows are treated across programs, see no-show and billing for no-shows.

Nebraska: 52 marks a trip outside Lincoln and Omaha

Nebraska’s billing instructions for fee-for-service Medicaid NEMT (CMS-1500, box 24D) say the 52 modifier listed on the fee schedule for T2003 “is used for trips not wholly within the corporate city limits of Lincoln or Omaha.” The fee schedule, 471-000-503, revised July 1, 2026, lists both amounts:

Code	Without 52	With 52
T2003, trip	$19.69	$9.41
T2001, attendant or escort	$2.87	$6.05

The schedule says the base rate includes the first five loaded miles, unloaded mileage, and usual waiting time, and that loaded mileage is covered “when travel exceeds six or more miles.” S0215 and S0209 pay $1.85 a mile.

The instructions define 52 only for T2003, and they do not say why the out-of-city amount is lower. They also do not say what 52 marks on T2001, where the amount goes up, and they carry no date, though the July 1, 2026 schedule still lists both 52 rows. Call Nebraska Medicaid claims customer service at 877-255-3092, option 1, before you bill either line. These instructions cover fee-for-service members. Members in a Heritage Health plan get rides through their plan’s own broker (see the Nebraska guide).

Example. You drive a member from a home inside Omaha to a clinic in a town outside the city limits. The trip is not wholly within Omaha, so line 1 is T2003 with 52 and one trip, which pays $9.41. A trip that starts and ends inside Omaha bills T2003 with no modifier and pays $19.69. See T2003 and T2001 for how each code works.

New Jersey: 52 marks a self-directed employee’s ride time

New Jersey’s Division of Developmental Disabilities (DDD) pays for rides that help participants in its Supports Program and Community Care Program reach services, activities, and community resources. Section 17.21 of both manuals (September 2025) lists three transportation codes:

A0090HI22, multiple passenger rate, per mile. NJ Medicaid’s procedure listing (updated September 1, 2026) shows $0.77. CPT defines 22 as increased procedural services, so here again the payer’s meaning is the one that counts.
A0090HI, single passenger rate, per mile, at a reasonable and customary rate the Division approves in advance.
A0090HI52, self-directed employee, per 15 minutes.

A self-directed employee is someone the participant hires directly. A NEMT company’s own drivers are not self-directed employees, so a company bills the passenger rates, not 52. The Supports manual (section 8.3.2.0.2) says this service pays the employee for their time and their mileage, and that the wage is negotiated case by case. NJ Medicaid’s listing shows the rate as “by report.” See New Jersey DDD transportation and A0090 for the rest.

How to use 52 without a denial

Look for 52 in your payer’s own schedule, beside the exact code you are billing.
Read what it names. A no-show, an out-of-city trip, and a self-directed employee are different claims.
Leave it off when the schedule is silent. A modifier you were not asked for can deny the line.
Keep the proof the payer asks for. For South Country, that is the no-show report and a record of all activity connected to the no-show. For Nebraska, keep a record of all trips to support your billing, as the instructions tell you for audits.
Ask the payer in writing when its schedule lists 52 on a code its instructions do not explain, as Nebraska does for T2001.

Frequently asked questions

What does the 52 modifier mean in medical billing?

In CPT, the physician code set the AMA publishes, modifier 52 means reduced services. CMS's Medicare Claims Processing Manual (Chapter 4, May 28, 2026) describes it, for hospital outpatient claims, as showing partial reduction, cancellation, or discontinuation of a service without changing the code for the basic service. A ride is not a reduced procedure, so any 52 on a NEMT claim carries the meaning your payer gives it.

What does 52 mean on a NEMT claim?

It depends on the payer. As of October 2026, South Country Health Alliance in Minnesota uses it on no-show lines, Nebraska Medicaid uses it on T2003 for trips not wholly within the corporate limits of Lincoln or Omaha, and New Jersey's Division of Developmental Disabilities uses it on A0090HI52 for a self-directed employee's ride time. Find 52 beside your exact code in your payer's fee schedule or manual.

How do I bill a no-show with modifier 52 in Minnesota?

Only for South Country Health Alliance, and only as a contracted provider. Report the no-show to RideConnect by secure email with the member's name, ID number, and date, then bill the no-show line the manual lists for the ride type, with 52, one unit, no mileage, and no other code. Do not copy this to other Minnesota payers. MTM Health's Minnesota provider page says it does not reimburse no-shows.

Why is T2003 with modifier 52 lower in Nebraska?

Nebraska's fee schedule of July 1, 2026 pays T2003 at $19.69 and T2003 with 52 at $9.41, and the state's billing instructions say 52 marks trips not wholly within the corporate city limits of Lincoln or Omaha. The schedule does not say why the amounts differ, so ask Medicaid claims customer service at 877-255-3092, option 1, before you assume how mileage is paid on those trips.

What is A0090HI52 in New Jersey?

It is the code for transportation by a self-directed employee in the Division of Developmental Disabilities Supports Program and Community Care Program, billed per 15 minutes. The September 2025 manuals set the pay as a reasonable and customary rate, and the Supports manual says the wage is negotiated case by case. The participant hires the employee, and a fiscal intermediary pays them.

Can I add 52 to a claim when a trip was cut short?

Not on your own. Federal Medicaid coding policy (revision date January 1, 2026) says states may deny or reject claim lines on which a modifier is used inappropriately. If a trip ended early, follow your payer's rule for it, such as a no-show or dry-run line, and use 52 only where the payer's schedule lists it for that code.
