Expansion of Coverage for
Chiropractic Services Demonstration (MMA)

Available as a Word Document

Billing rules from this whole article are summed up here: (updated 5-21-2005)

(These rules are for Illinois, although it "should" be the same for all the demo sites:

  1. Billing for the CMT (98940-42) will be the same rules as before the project (that is, the CMT codes must have the -AT modifier (active therapy), or it will be rejected as "maintenance care")

  2. Billing Demonstration project codes – you must put them on a separate claim form and you must use the diagnosis codes listed in this article. So when you are billing for demo codes PLUS CMT you will use 2 different claim forms.

  3. You must put "demo 45" in box 19 of a CMS1500 form or in the ASCX12837 electronic format, you should report the demonstration number in the 2300/REF loop. In addition to demo 45, you MUST have the date last seen (or assessed) and UPIN of attending physician. So Box 19 must be "demo 45 xx/xx/xxxx U12345" but with dates and correct UPIN of coarse. PLEASE DO NOT MAKE THE MISTAKE, a UPIN is different then a PIN. Put the UPIN in Box 19.

  4. Box 17 - Must have referring doctors name or if there is no referring, put attending/ordering doctors name

  5. Box 17A - Must have UPIN of referring/attending doctor

  6. You must use AT modifier on ALL codes that are active treatment and not maintenance care.

  7. You must put an AT & GP modifier on all Physical therapy codes (excluding 64550)

  8. You must put an AT & 25 modifier on all E & M codes (office visits)

  9. You must put an AT modifier on the CMT codes

  10. Have a new plan of care every 30 days (following the re-exam)

  11. Change Box 14’s dates according to description below from the CMS guidelines (see page 3)

  12. Make sure your documentation is in order to back up all the procedures you do, everything has to be documented or it wasn’t done.

The Use of CPT Modifiers:

AT = Active Therapy

GP = Identifies it as a Physical Therapy (PT) covered under the demonstration project

GY= a non-covered service. If you supply PT to a patient in a non-demonstration project area, you still want Medicare to know that chiropractors provide this type of service. You must also signify that the patient knows Medicare won't be paying for it with the GY modifier.

GA = is a REQUIRED modifier that MUST be used whenever you have an ABN signed

GZ = is an optional, although strongly recommended, modifier that signifies
you know you should have had an ABN signed but, for some reason, did not.

-25 = Significant, separately identifiable E&M service, provided by the same physician on the same day as another procedure which also contains a pre- and post-treatment assessment.

-51 = Multiple Procedures modifier

-52 = Reduced Services Modifier

-59 = Distinct Procedural Service This advises that the second service was distinct or separate from other services performed on the same day.


Provider Types Affected

Chiropractors who practice in the States of Maine and New Mexico, Scott County, Iowa, 26 counties in Illinois (including Cook, DeKalb, DuPage, Grundy, Kane, Kendall, McHenry, Will, Boone, Bureau, Carroll, Henry, JoDaviess, Kankakee, Lake, LaSalle, Lee, Marshall, Mercer, Ogle, Putnam, Rock Island, Stark, Stephenson, Whiteside, and Winnebago counties), and 17 counties in central Virginia (including Pittsylvania, Campbell, Appomattox, Nelson, Buckingham, Fluvanna, Louisa, Caroline, Hanover, New Kent, Henrico, Richmond City, Danville City, Goochland, Cumberland, Powhatan, and Amelia counties).

Provider Action Needed

Under a two-year demonstration project beginning April 1, 2005, doctors of chiropractic will be able to bill Medicare carriers for the Part B medical, radiology, clinical lab, and therapy services that they provide for their Medicare fee-for-service patients. These services must be billed separately from current services that are covered under Medicare. You must include a demonstration code for all demonstration claims.

Under this demonstration, doctors of chiropractic will also be allowed to bill Medicare for CPT code 98943—extraspinal manipulation. The fee amounts for 98943 per geographic area can be found in Table 1 of this article. Coverage will also be expanded to include other ancillary services chiropractors are legally allowed to provide and Medicare currently covers. These procedures include electrotherapy, ultrasound, TENS therapy, and other services that are medically necessary for the treatment of neuromusculoskeletal conditions. Chiropractors will be allowed to provide physical therapy services and to refer patients for therapy under this demonstration.

Chiropractors will also be reimbursed for Evaluation and Management (E&M) services delivered for neuromusculoskeletal conditions. Under the demonstration, chiropractors will be allowed to bill Medicare for both an E&M visit and for treatment the first time you assess a patient, as well as for current patients in instances such as when there is a new condition, exacerbation or recurrence of the current condition, or for a reassessment midway through treatment.

Chiropractors should not bill for an E&M service every time they treat a patient. Chiropractors billing Medicare under this demonstration must follow the same documentation guidelines that physicians follow for E&M services.

For example, chiropractic manipulation codes include a brief pre-manipulation patient assessment. Additional E&M services may be reported separately using the modifier "-25" if, and only if, the patient’s condition requires a significant separately identifiable E&M service. When manipulation and E&M codes are billed for the same visit, it is necessary to attach a "-25" modifier to the E&M code. These guidelines can be found at:

Additional E&M guidance can also be found in the Medicare Claims Processing Manual, publication 100- 04, Chapter 12, Section 30. This manual may be accessed at:


Services provided under this demonstration must be related to acute or active treatment, not maintenance or prevention of neuromusculoskeletal conditions. You must place an AT modifier next to every CPT code on all claims when providing active/corrective treatment to treat acute or chronic subluxation.

You should be aware that while under this demonstration, chiropractors will be subject to the same coverage and payment rules that physicians and physical therapists must follow, such as:

  1. rules that apply to physicians regarding billing for the delivery of E&M services and treatment in the same visit;

2) coinsurance or deductible rules; and 3) rules regarding the delivery of physical therapy services, including identifying these services using the GP modifier, and certifying the plan of care every 30 days. These requirements can be found in the Medicare Benefit Policy Manual 100-2 in Chapter 15, Sections 220 and 230 and the Medicare Claims Processing Manual 100-4 in Chapter 5, Section 20 and other manual sections.


The Medicare Benefit Policy Manual may be found at:

In addition, chiropractors must follow physician rules for providing therapy services under the "incident to" provision of the physician regulation. When a physical therapy service is provided incident to the service of a chiropractor, the person who furnishes the service must meet the standards and conditions that apply to physical therapists, except that a license is not required.

This means that unless chiropractic students, chiropractic assistants, or sports trainers have graduated from a physical therapy curriculum approved by:

1) the American Physical Therapy Association, or 2) The Committee on Allied Health Education and Accreditation of the American Medical Association, or 3) the Council on Medical Education of the American Medical Association and the American Physical Therapy Association, they cannot provide therapy services incident to a chiropractor. The only exception is that certain persons trained prior to January 1, 1966 may be grandfathered (see 42 CFR 484.4).

Finally, you should check your local Medicare carrier website for information on local coverage decisions regarding demonstration services.


Rules from this whole article summed up:

  1. Billing for the CMT (98940-42) will be the same rules as before the project

  2. Billing Demonstration project codes – you must put them on a separate claim form and you must use the diagnosis codes listed in this article. So when you are billing for demo codes PLUS CMT you will use 2 different claim forms

  3. You must put "demo 45" in box 19 of a CMS1500 form or in the ASCX12837 electronic format, you should report the demonstration number in the 2300/REF loop

  4. You must use AT modifier on ALL codes that are active treatment and not maintenance care.

  5. You must put an AT & GP modifier on all Physical therapy codes (excluding 64550)

  6. You must put an AT & 25 modifier on all E & M codes (office visits)

  7. You must put an AT modifier on the CMT codes

  8. Have a new plan of care every 30 days

  9. Change Box 14’s dates according to description below from the CMS guidelines

  10. Make sure your documentation is in order to back up all the procedures you do, everything has to be documented or it wasn’t done.


Box 14:

Enter either an 8-digit (MM/DD/CCYY) or 6-digit (MM/DD/YY) date of current illness, injury, or pregnancy.  For chiropractic services, enter an 8-digit (MM/DD/CCYY) or 6-digit (MM/DD/YY) date of the initiation of the course of treatment.  

Therefore if a patient comes in with a neck injury on Monday June 2, 1999 you will put 06/02/1999 in box 14, BUT then if she comes back on June 5th, 1999 with a lower back pain, you would change the date in box 14 to 06/05/1999.

    • Aggregate Medicare provider payments may not exceed amount that would have been paid in absence of demonstration.

If demonstration is not found to be cost neutral (based on it’s estimated impact on Medicare Part A and Part B costs), CMS will RECOUP excess costs via payments made to all Medicare chiropractic service providers

  • CMS anticipates any necessary fee reduction to be made in the 2010 and 2011 fee schedules

  • If CMS determines that the adjustment would exceed 2% of chiropractor fee schedule, it will implement the adjustment over a 2 year period

Detailed analysis of budget neutrality and proposed offset will be published in the 2009 Federal Register publication of physician fee schedule.
