Billing and coding: diagnoses and procedure codes
Since 2019 the codes live in the companion article rather than the LCD. Billing and Coding A56455 (Billing and Coding: Chiropractic Services) carries the diagnosis and procedure lists the contractor loads as the claims edit. CPT codes are shown as bare numbers because the descriptors are licensed by the AMA; HCPCS Level II descriptors are public and shown.

Coverage indications, limitations and medical necessity
Abstract:
Chiropractic manipulative treatment (CMT) is a form of manual treatment to influence joint and neurophysiological function. This treatment may be accomplished using a variety of techniques. Medicare covers limited chiropractic services when performed by a chiropractor who is licensed or legally authorized to furnish chiropractic services by the State or jurisdiction in which the services are furnished (CMS Publication 100-01, Medicare General Information, Eligibility and Entitlement Manual, Chapter 5, Section 70.6). A chiropractor must also meet uniform minimum standards as set forth in the CMS Internet-Only Manual (IOM) Publication 100-1, Chapter 5, Section 70.6. This policy restates language directly from the CMS Internet-Only manuals and if necessary provides clarification to educate providers on specified Medicare requirements for the diagnosis, treatment, documentation and billing of chiropractic services.
Indications
Chiropractic Services – Active Treatment:
The patient must have a significant health problem in the form of a neuromusculoskeletal condition necessitating treatment, and the manipulative services rendered must have a direct therapeutic relationship to the patient’s condition and provide reasonable expectation of recovery or improvement of function. The patient must have a subluxation of the spine as demonstrated by x-ray or physical exam. (CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15, Section 240.1.3)
Most spinal joint problems fall into the following categories:
Acute subluxation - A patient’s condition is considered acute when the patient is being treated for a new injury, identified by x-ray or physical exam as specified above. The result of chiropractic manipulation is expected to be an improvement in, or arrest of progression, of the patient’s condition.
Chronic subluxation - A patient’s condition is considered chronic when it is not expected to significantly improve or be resolved with further treatment (as is the case with an acute condition), but where the continued therapy can be expected to result in some functional improvement. Once the clinical status has remained stable for a given condition, without expectation of additional objective clinical improvements, further manipulative treatment is considered maintenance therapy and is not covered. (CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15, Section 240.1.3)
An acute exacerbation is a temporary but marked deterioration of the patient’s condition that is causing significant interference with activities of daily living due to an acute flare-up of the previously treated condition. The patient’s clinical record must specify the date of occurrence, nature of the onset, or other pertinent factors that would support the medical necessity of treatment. As with an acute injury, treatment should result in improvement or arrest of the deterioration within a reasonable period of time.
A. Maintenance Therapy
Maintenance therapy includes services that seek to prevent disease, promote health and prolong and enhance the quality of life, or maintain or prevent deterioration of a chronic condition. When further clinical improvement cannot reasonably be expected from continuous ongoing care, and the chiropractic treatment becomes supportive rather than corrective in nature, the treatment is then considered maintenance therapy. (CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15, Section 240.1.3A)
B. Contraindications
Dynamic thrust is the therapeutic force or maneuver delivered by the physician during manipulation in the anatomic region of involvement. A relative contraindication is a condition that adds significant risk of injury to the patient from dynamic thrust, but does not rule out the use of dynamic thrust. The doctor should discuss this risk with the patient and record this in the chart. (CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15, Section 240.1.3B)
The following are relative contraindications to Dynamic thrust:
Articular hyper mobility and circumstances where the stability of the joint is uncertain;
Severe demineralization of bone;
Benign bone tumors (spine);
Bleeding disorders and anticoagulant therapy; and
Radiculopathy with progressive neurological signs.
(CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15, Section240.1.3B) Dynamic thrust is absolutely contraindicated near the site of demonstrated subluxation and proposed manipulation in the following:
Acute arthropathies characterized by acute inflammation and ligamentous laxity and anatomic subluxation or dislocation; including acute rheumatoid arthritis and ankylosing spondylitis;
Acute fractures and dislocations or healed fractures and dislocations with signs of instability;
An unstable os odontoideum;
Malignancies that involve the vertebral column;
Infection of bones or joints of the vertebral column;
Signs and symptoms of myelopathy or cauda equina syndrome;
For cervical spinal manipulations, vertebrobasilar insufficiency syndrome; and
A significant major artery aneurysm near the proposed manipulation.
(CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15, Section 240.1.3B)
Limitations
The term “physician” under Part B includes a chiropractor who meets the specified qualifying requirements set forth in §30.5 but only for treatment by means of manual manipulation of the spine to correct a subluxation. (CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15, Section 240)
Coverage extends only to treatment by means of manual manipulation of the spine to correct a subluxation provided such treatment is legal in the State where performed. All other services furnished or ordered by chiropractors are not covered. (CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15, Section 30.5)
Coverage of chiropractic service is specifically limited to treatment by means of manual manipulation, i.e., by use of the hands. Additionally, manual devices (i.e., those that are hand-held with the thrust of the force of the device being controlled manually) may be used by chiropractors in performing manual manipulation of the spine. However, no additional payment is available for use of the device, nor does Medicare recognize an extra charge for the device itself. (CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15: Section 240.1.3)
No other diagnostic or therapeutic service furnished by a chiropractor or under the chiropractor’s order is covered. This means that if a chiropractor orders, takes, or interprets an x-ray, or any other diagnostic test, the x-ray or other diagnostic test, can be used for claims processing purposes, but Medicare coverage and payment are not available for those services. This prohibition does not affect the coverage of x-rays or other diagnostic tests furnished by other practitioners under the program. For example, an x-ray or any diagnostic test taken for the purpose of determining or demonstrating the existence of a subluxation of the spine is a diagnostic x-ray test covered under §1861(s)(3) of the Act if ordered, taken, and interpreted by a physician who is a doctor of medicine or osteopathy. (CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15, Section 240.1.1)
The mere statement or diagnosis of "pain" is not sufficient to support medical necessity for the treatments. The precise level(s) of the subluxation(s) must be specified by the chiropractor to substantiate a claim for manipulation of each spinal region(s). There are five spinal regions addressed by this LCD: cervical region (atlanto-occipital joint), thoracic region (costovertebral/costotransverse joints), lumbar region, pelvic region (sacro-iliac joint) and sacral region (ref. CPT® Professional Edition 2017 p. 672).
Medicare does not cover chiropractic treatments to extraspinal regions (CPT 98943).The five extraspinal regions are: head (including temporomandibular joint, excluding atlanto-occipital) region; lower extremities; upper extremities; rib care (excluding costotransverse and costovertebral joints) and abdomen (CPT Assistant Nov 98:38).
The five extraspinal regions referred to are: head (including, temporomandibular joint, excluding atlanto-occipital) region; lower extremities; upper extremities; rib cage (excluding costotransverse and costovertebral joints) and abdomen (CPT Assistant Nov 98:38). Medicare does not cover chiropractic treatments to extraspinal regions (CPT 98943), which includes the head, upper and lower extremities, rib cage and abdomen.
For Medicare purposes, a chiropractor must place an AT modifier on a claim when providing active/corrective treatment to treat acute or chronic subluxation. However the presence of the AT modifier may not in all instances indicate that the service is reasonable and necessary. As always, contractors may deny if appropriate after medical review. (CMS Publication 100-02, Medicare Benefit Policy Manual , Chapter 15, Section 240.1.3) Modifier AT must only be used when the chiropractic manipulation is “reasonable and necessary” as defined by national policy and the LCD. Modifier AT must not be used when maintenance therapy has been performed. The need for a prolonged course of treatment should be appropriate to the reported procedure code(s) and medical necessity must be documented clearly in the medical record.

Using this policy on a claim
Match the documented indication to the covered indications above before the service is scheduled, carry a diagnosis from the article's covered list on the claim line, and keep the elements the documentation section asks for in the record, because the contractor can request it later through medical review. A denial under this policy arrives as CARC 50 with remark N115; the LCD lookup guide walks through the appeal path and the Advance Beneficiary Notice rules, and the CGS Administrators, LLC hub lists every other active policy from the same contractor.
The same policy title at other contractors
Contractors often adopt each other's policies and then revise them separately, so the criteria and the diagnosis lists drift apart. The topic comparison lines up every version.
Frequently asked questions
What does LCD L37254 cover?
Chiropractic manipulative treatment (CMT) is a form of manual treatment to influence joint and neurophysiological function. This treatment may be accomplished using a variety of techniques. Medicare covers limited chiropractic services when performed by a chiropractor who is licensed or legally authorized to furnish chiropractic services by the State or jurisdiction in which the services are furnished (CMS… The full indications and limitations are reproduced on this page from the CMS Medicare Coverage Database export of September 24, 2026.
Which states does LCD L37254 apply to?
CGS Administrators, LLC applies it to Medicare claims in KY, OH. A Local Coverage Determination binds only the contractor that wrote it; the same service in another jurisdiction is judged under that contractor's own policy or, where none exists, claim by claim.
Which diagnosis codes support medical necessity under LCD L37254?
The companion billing and coding article A56455 lists 5 ICD-10-CM codes in 1 group that support medical necessity; the first 5 appear on this page and the complete list is in the article on cms.gov.
How do I appeal a denial under LCD L37254?
The remittance carries claim adjustment reason code 50 with remark code N115, naming the LCD. Compare the documented indication with the policy's covered indications and the article's diagnosis list, then file a redetermination within 120 days with the record attached; if the service genuinely falls outside the policy, the patient can be billed only when a valid Advance Beneficiary Notice was obtained before the service.
