Chiropractic Services - CAM 065
Description:
Chiropractic manipulative treatment (CMT) is a form of manual treatment proposed to influence joint and neurophysiological function. The primary mode of chiropractic treatment is manipulation or adjustment. This treatment may be accomplished using a variety of techniques. Manipulation is the application of a controlled force and is proposed to re-establish normal articular function. The objective of manipulation is to restore the normal mobility and range of motion within the joint. The chiropractic manipulative treatment codes include a pre-manipulation patient assessment. For the purposes of CMT, the five spinal regions referred to are:
-
Cervical region (includes atlanto-occipital joint)
-
Thoracic region (includes costrovertebral and costotransverse joints)
-
Lumbar region
-
Sacral region
-
Pelvic region (sacro-iliac joint)
Policy:
Chiropractic Services may be considered MEDICALLY APPROPRIATE when ALL of the following criteria are met:

Policy Statement:
**Many contracts do not have benefit coverage for these services. For information relating to coverage benefits, limitations and/or exclusions, please refer to the specific plan of benefits.**
Definitions:
Adjunct Modalities:
In addition to spinal manipulation, which is a manual therapy, other modalities, both passive and active, are often used as adjunct treatments. Passive modalities include treatments such as electrical stimulation, therapeutic ultrasound, high-voltage galvanic stimulation, therapeutic heat, cryotherapy, passive assistive exercise, traction, diathermy and massage. Passive modalities are most effective during the acute phase of treatment, as they are typically directed at reducing pain and swelling. They may also be used during the acute phase of an exacerbation of a chronic condition. The optimal duration of a course of passive modalities is a maximum of one to two months, after which their effectiveness diminishes, and patient dependency may develop. Treatment plans for patients who are at risk for developing chronic conditions should de-emphasize passive care and refocus on active care approaches. When utilizing passive modalities after a lasting physiological benefit has been reached, the modalities serve only to facilitate the manipulation and are considered integral to the manipulative procedure.
Digital Postural Analysis:
Posture analysis is a method by which deviation in posture may be determined, theoretically identifying areas that are likely to cause or are causing pain. Various systems may be utilized to conduct posture analysis and include software systems for analyzing digital/video images. Following the procedure, a report is produced identifying posture deviations. Postural analysis may be used to document posture before and after treatment sessions, to educate individuals regarding deviations and causes of pain and to customize and monitor treatment plans. However, there is lack of evidence in the peer-reviewed published scientific literature evaluating this technology and conclusions cannot be drawn regarding the added benefit of digital postural analysis and how this technology affects treatment plans to improve clinical outcomes.
Digital Radiographic Mensuration:
Digital radiographic mensuration, also referred to as radiographic digitization, or computer-aided radiographic mensuration analysis (CRMA), refers to a computerized analysis of osseous geometric relationships, often employed as part of postural analysis. Mensuration is a term that refers to chiropractic line measurements, with or without computer digitalization and may be used to assess subluxation and alignment. Historically, chiropractic line measurements were drawn manually on radiographs with the use of rulers, pencils and protractors. Manual marking techniques may lead to error and more recently, computer aided or digitalized mensuration has been utilized, theoretically providing results more rapidly and with less variance. Although published data comparing digital radiograph mensuration to manual methods is limited, a few results for reliability testing have been published and lend some support to concurrent validity when compared to manual methods (Troyanovich, et al., 2000). However, well-designed clinical trials supporting efficacy are lacking in the medical literature and there is insufficient evidence to support that the use of this technology adds any benefit or improvement of health outcomes when compared to standard chiropractic techniques.
Supportive Care: Supportive care is long-term treatment/care for patients who have reached maximum therapeutic benefit, but who fail to sustain benefit and progressively deteriorate when there are periodic trials of treatment withdrawal. Supportive care follows appropriate application of active and passive care including rehabilitation and/or lifestyle modifications.
Preventive/Maintenance Care: Elective health care that is typically long-term, by definition not therapeutically necessary but is provided at preferably regular intervals to prevent disease, prolong life, promote health and enhance the quality of life. This care may be provided after maximum therapeutic improvement, without a trial of withdrawal of treatment, to prevent symptomatic deterioration or it may be initiated with patients without symptoms in order to promote health and to prevent future problems. This care may incorporate screening/evaluation procedures designed to identify developing risks or problems that may pertain to the patient's health status and give care/advice for these. Preventive/maintenance care is provided to optimize a patient's health. Maintenance begins when the therapeutic goals of a treatment plan have been achieved and when no further functional progress is apparent or expected to occur.
Various manipulative/adjustment techniques may be employed by doctors of chiropractic, and practitioners may vary in the approaches utilized. The term "spinal manipulation" refers to all types of manual techniques. While many techniques are taught both in and outside the established curriculum, the most widely taught techniques include the following:
- Diversified: This is the most commonly used of all techniques and employs a high-velocity, low- amplitude thrust that usually results in cavitation of a joint.
- Extremity manipulation/adjusting: This application is used for joints other than the spine, such as the shoulder, elbow, wrist, hand, finger, hip, knee, etc., and may be used for carpal tunnel syndrome, gait or posture-related problems.
- Activator methods: This employs the use of a hand-held spring-loaded instrument-based manipulation/adjustment protocol. Force is generated by the appliance (e.g., Activator Adjusting Instrument [Activator Methods International, Ltd., Phoenix, AZ]; AcuWave [Sigma Instruments, Inc. Cranberry, PA]) and can be used as a primary treatment method for all patients.
- Gonstead: This technique is a variation of the Diversified technique and utilizes manipulation/ adjustment by hand that results in joint cavitation, and may use radiograph analysis, palpation, and temperature gradient studies to determine which segments to manipulate.
- Cox flexion distraction: This technique employs the use of mechanical and hands-on manipulation/adjustment by utilizing a special table where traction is applied to the spine and the spine is flexed forward. This technique requires active participation from the physician and is not primarily mechanical and provider passive such as with mechanical traction or a traction table. It is primarily used to treat disc herniation, non-disc spinal disorders, and to increase mobility of the spinal joints.
- Thompson: This is also a variation of the Diversified technique using a table with several segments called drop pieces. The drop pieces assist the thrust while minimizing the force used for the manipulation/adjustment.
Provider Record Keeping Requirements for Chiropractic Manipulative Treatments
General Requirements
Chiropractors must maintain medical records which comport with the record keeping standards of the chiropractic profession. However, to the extent the chiropractic profession’s record keeping standards do not already require it, for a chiropractor to be reimbursed for claims for chiropractic manipulative treatments (CPT Codes 98940 through 98943), the medical records he or she creates and maintains for his patients must also comply with the following requirements:
- The date and the patient’s name must appear on each page of the medical record.
- Each patient encounter must be a separate record.
- The patient’s entire record must be legible (i.e., must be legible to someone other than the writer).
- Entries in the medical record must be made within a week of the chiropractor performing the chiropractic manipulative treatments.
- The medical record must demonstrate that the chiropractic manipulative treatments are medically necessary.
- The medical records must demonstrate that the patient’s treatment plan is consistent with his or her diagnoses.
- CPT codes and ICD codes reported on claim forms or billing statements are supported by the documentation in the medical record.
- The chiropractor must provide a definition sheet of abbreviations specific to his or her office to assist BCBSSC in interpreting patients’ medical records.
Documentation corrections should be single line drawn through the error with the corrected text in close proximity, initialed and dated by the person who made the error.
Treatment Notes/Patient Encounter Notes
In addition, to the extent the chiropractic profession’s record keeping standards do not already require it, for a chiropractor to be reimbursed for claims for chiropractic manipulative treatments, the following information must be recorded by the chiropractor in each individual record of a patient encounter.
A. Initial Visit: The following information must be included in a patient’s medical record for the patient’s initial visit:
- A patient history. The patient history must contain a description of:
- The symptoms causing the patient to seek treatment.
- The patient’s family history, if relevant.
- The patient’s past health history (general health, prior illness, injuries, or hospitalizations; medications; surgical history).
2. A description of the present illness, including:
- The mechanism of trauma.
- The quality and character of the patient’s symptoms/problem(s).
- The onset, duration, intensity, frequency, location, and radiation of symptoms.
- Any aggravating or relieving factors.
- Any prior interventions, treatments, medications, secondary complaints.
- The symptoms causing patient to seek treatment — These symptoms must bear a direct relationship to the level of subluxation. The symptoms should refer to the spine, muscle, bone, rib and joint and be reported as pain, inflammation, or as signs such as swelling, spasticity, etc. Vertebral pinching of spinal nerves may cause headaches, arm, shoulder, and hand problems as well as leg and foot pains and numbness. Rib and rib/chest pains are also recognized symptoms, but in general other symptoms must relate to the spine as such. The subluxation must be causal, i.e., the symptoms must be related to the level of the subluxation that has been cited. A statement in the patient’s medical record that there is "pain" is insufficient. The location of pain must be described and whether the particular vertebra listed is capable of producing pain in the area determined.
3. An evaluation of the musculoskeletal/nervous system through physical examination.
4. Diagnosis.
5. Treatment Plan: The treatment plan must include the following:
- The recommended level of care (duration and frequency of visits)
- The specific treatment goals
- The objective measures to be used to evaluate treatment effectiveness
6. A description of the treatment given on the patient’s initial visit, if any.
7. The legible signature and professional identification of the individual who furnished the chiropractic manipulative treatments.
B. Subsequent Visits: The following information must be included in a patient’s medical record for the patient’s subsequent visits:
1. A patient history
-
Review of chief complaint, which should include the date of initial treatment or date of exacerbation of the existing condition
-
Changes since last visit
-
System review, if relevant
2. A physical examination of the patient, which includes:
-
An exam of the area of the spine involved in the diagnosis.
-
An assessment of the change in the patient’s condition since his/her last visit.
-
An evaluation of the effectiveness of the patient’s treatment(s).
3. A description of the treatment given.
4. The legible signature and professional identification of the individual who furnished the chiropractic manipulative treatments.
REMINDER:
BlueCross BlueShield of South Carolina does not recognize incident-to billing but requires that claims be billed under the name of the provider who actually rendered the service(s), including chiropractic manipulative treatments.
