Collaboration is a process of working together to complete a task or achieve a goal.

For the Clinical Documentation Integrity Specialist, the goal of ensuring a patient’s story can be accurately reflected in codes (ICD-10-CM/PCS, HCPCS, CPT), requires collaborating with a team that can include physicians, nursing, dietitians, physical therapists, case managers, social workers, and coding professionals.

For the Case Manager, to ensure a patient’s story supports medical necessity of the services being provided and the patient has an appropriate discharge plan in place, this process, in addition to the above professions, requires open communication with the patient and his or her “people.”

Physicians must also collaborate with a team. In fact, CMS recently updated their MLN Fact Sheet: Collaborative Patient Care is a Provider Partnership (link). This Fact Sheet opens with the following guidance:

“As a physician, supplier, or other health care provider, you may need to collaborate with other providers when providing care to your Medicare patients. For example, you may:

• Write orders
• Make referrals
• Request health care services or items for your patient

It’s important to understand Medicare coverage criteria and documentation requirements that apply for those services or items. This helps to ensure:

• Quality care for your patient
• Accurate and timely processing and payment of:
• Your claims, and
• The claims of other providers or suppliers who provide services or items for your patient

Note: This fact sheet is limited to information and documentation you need to support medical necessity when you partner with other providers. Other coverage and payment rules may also apply.”

Medicare Coverage Criteria and Documentation Requirements

Title XVIII of the Social Security Act, Section 1862 (a)(1)(A) states “No payment may be made under Part A or Part B for expenses incurred for items or services which…are not reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member…”

At the national level, CMS publishes National Coverage Determinations (NCDs) and at the local level, Medicare Administrative Contractors (MACs) publish Local Coverage Determinations (LCDs) and Local Billing and Coding Articles (LCAs). Coverage documents provide guidance for when a service is covered or not covered, and include indications for coverage, limitations of coverage, documentation requirements and billing and coding guidance.

It is important to become familiar with where to find these documents (Medicare Coverage Database (link) and identify any NCDs, LCDs, and/or LCAs that apply to services that you provide. For example, at the national level, there is a NCD for Implantable Automatic Defibrillators (20.4) (link). In addition to the NCD, several MACs have published a related Billing and Coding article.

Ensuring the Story is Correct

Understanding Medicare coverage criteria and documentation requirements is important. So much so, CMS utilizes Contractors (i.e., Recovery Auditors, Supplemental Medical Review Contractor, and MACs) to audit claims.

CMS notes in the MLN Fact Sheet, “Medicare audits frequently show that provider-submitted documentation doesn’t provide enough information to establish medical necessity. To ensure proper claims processing and payment, you must follow documentation requirements and meet Medicare coverage criteria.”

They also underscore the importance of documenting everything needed to meet Medicare payment requirements when collaborating with other Providers. For example, let us once again focus on implantable automatic defibrillators and the Shared Decision Making (SDM) encounter requirement. The SDM encounter is:

• A requirement for all patients receiving a defibrillator for primary prevention,
• Must occur between the patient and a Physician or Non-Physician Practitioner (i.e., Physician Assistant, Nurse Practitioner, or Clinical Nurse Specialist),
• An Evidenced-Based Decision Tool must be used to ensure topics like patient health goals and preferences are discussed,
• The encounter must occur prior to the initial implantation, and
• The encounter may occur at a separate visit.

Given the timing of when the SDM encounter should occur, it is likely that this would be done in the Physician’s office. Therefore, the physician would need to include in documentation provided to the hospital that an SDM encounter had occurred and what tool had been used.

CMS advises that a providers documentation needs to be thorough and accurate to support the medical necessity of services provided and should:

• Provide a thorough picture of what happened during the patient’s visit, and
• Tell why services or items you ordered or gave are medically necessary.
