Article Guidance

Article Text

 Cardiac Rehabilitation Program

  • The frequency and duration of the program is generally a total of 36 sessions over a maximum of 36 weeks.
  • A single session must last at least 31 minutes in order to be billable. If 2 sessions are billed for a single day, then the total combined time must be at least 91 minutes (60 minutes for the first session and at least 31 minutes for the second session) in duration.
  • No more than 2 1-hour sessions, utilizing any combination of the CPT® or HCPCS codes (93798, 93797 or G0422, G0423) will be allowed per day for up to 36 sessions over a maximum of 36 weeks (Phase IIA).
  • An additional 36 sessions may be allowed if a significant intercurrent illness or comorbidity occurred during the first 36 sessions and the exit criteria have not been met (Phase IIB). Inclusion of the KX modifier on the claim line(s) will be accepted as an attestation by the provider of the service that documentation is on file verifying that further treatment beyond 36 sessions of CR up to a total of 72 sessions meets the CR coverage requirements. The medical record must reflect the medical reasons for further treatment and be available to Medicare upon request.
  • An additional series of 36 sessions may be allowed as a new series of CR initiated after an intervening event described as an indication for CR in this article. Inclusion of the KX modifier on the claim line(s) will be accepted as an attestation by the provider of the service that documentation is on file verifying that an additional series of CR meets the CR coverage requirements.

Intensive Cardiac Rehabilitation Program (ICR)

A beneficiary may switch from an ICR program to a CR program. The beneficiary is limited to a 1-time switch, multiple switches are not allowable. Once the beneficiary switches from ICR to CR, he or she will be limited to the number of sessions remaining in the program. For example, a beneficiary who switches from ICR to CR after 12 sessions will have 24 sessions of CR remaining, (i.e., 12 sessions of ICR + 24 sessions of CR = total of 36 sessions).  Should a beneficiary experience more than 1 indication simultaneously, he or she may participate in a single series of CR or ICR sessions (i.e., a patient who had a myocardial infarction within 12 months and currently experiences stable angina is entitled to 1 series of CR sessions, up to 36 1-hour sessions with contractor discretion for an additional 36 sessions; or 1 series of ICR sessions, up to 72 1-hour sessions over a period up to 18 weeks). Beneficiaries may not switch from CR to ICR. Upon completion of a CR or ICR program, beneficiaries must experience another indication in order to be eligible for coverage of more CR or ICR.

Contractors shall accept the inclusion of the KX modifier on the claim line(s) as an attestation by the provider of the service that documentation is on file verifying that further treatment beyond 36 sessions of CR up to a total of 72 sessions meets the requirements of the medical policy or, for ICR, that any further sessions beyond 72 sessions within a 126 day period counting from the date of the first session or for any sessions provided after 126 days from the date of the first session meet the requirements of the medical policy.  Beneficiaries who switch from ICR to CR may also be eligible for up to 72 combined sessions with contractor discretion for CR sessions after 36 (to include completed ICR sessions prior to switch). In these cases, and consistent with the information above, the KX modifier must be included on the claim should the beneficiary participate in more than 36 CR sessions following the switch.

ICD-10-CM diagnosis codes supporting medical necessity must be submitted with each claim. Claims submitted without such evidence will be denied as not medically necessary.

Any diagnosis submitted must have documentation in the patient’s record to support coverage and medical necessity.

IF rendering CR or ICR services that involve ECG monitoring, the medical record must document performance of such monitoring. This should not be construed as a requirement for ECG monitoring for all CR or ICR services. Reported CPT® codes should accurately capture the service that was performed.

Under Article Text - Intensive Cardiac Rehabilitation Program (ICR) revised the verbiage to read “A beneficiary may switch from an ICR program to a CR program. The beneficiary is limited to a one-time switch, multiple switches are not allowable. Once the beneficiary switches from ICR to CR he or she will be limited to the number of sessions remaining in the program. For example, a beneficiary who switches from ICR to CR after 12 sessions will have 24 sessions of CR remaining, (i.e., 12 sessions of ICR + 24 sessions of CR = total of 36 sessions).  Should a beneficiary experience more than one indication simultaneously, he or she may participate in a single series of CR or ICR sessions (i.e., a patient who had a myocardial infarction within 12 months and currently experiences stable angina is entitled to one series of CR sessions, up to 36 1-hour sessions with contractor discretion for an additional 36 sessions; or one series of ICR sessions, up to 72 1-hour sessions over a period up to 18 weeks). Beneficiaries may not switch from CR to ICR. Upon completion of a CR or ICR program, beneficiaries must experience another indication in order to be eligible for coverage of more CR or ICR.

Contractors shall accept the inclusion of the KX modifier on the claim line(s) as an attestation by the provider of the service that documentation is on file verifying that further treatment beyond 36 sessions of CR up to a total of 72 sessions meets the requirements of the medical policy or, for ICR, that any further sessions beyond 72 sessions within a 126 day period counting from the date of the first session or for any sessions provided after 126 days from the date of the first session meet the requirements of the medical policy.  Beneficiaries who switch from ICR to CR may also be eligible for up to 72 combined sessions with contractor discretion for CR sessions after 36 (to include completed ICR sessions prior to switch). In these cases and consistent with the information above, the KX modifier must be included on the claim should the beneficiary participate in more than 36 CR sessions following the switch”.

 

At this time 21st Century Cures Act will apply to new and revised LCDs that restrict coverage which requires comment and notice. This revision is not a restriction to the coverage determination; and, therefore not all the fields included on the LCD are applicable as noted in this policy.

 

01/19/2017 R5 Annual validation performed-no changes made.
01/22/2016 R4 Under Article Text added the first sentence related to italicized text. Under Article Text-Cardiac Rehabilitation Program in the last sentence of the fourth bullet added”…the medical reasons for further treatment…” Under Article Text-Intensive Cardiac Rehabilitation Program deleted the existing verbiage for the second bullet and added the language as found in the CMS Internet-Only Manual. This revision becomes effective 01/22/2016.
06/25/2015 R3 Per CMS Internet-Only Manual, Pub 100-08, Medicare Program Integrity Manual, Chapter 13, §13.1.3 LCDs consist of only “reasonable and necessary” information. All bill type and revenue codes have been removed from the LCDs. For consistency, they are also being removed from the articles.
10/01/2015 R2 Under Associated Contract Numbers added 11202, 11302, 11402 and 11502.
