Proper documentation not only protects the provider, the payer, and the patient, it protects the integrity of the entire healthcare system. When it comes to coverage and documentation for durable medical, the DMEPOS supplier and staff must be familiar with the National and Local Coverage Determinations (NCDs and LCDs) as these are two of the most important aspects of Medicare. 

NCDs and LCDs are used by Medicare and their administrative contractors for coverage determination information and determining if the service is reasonable and necessary, as well as if it will be reimbursed by Medicare. Medicare and its contractors are not the only payers to follow these determinations. Additionally, many other payers have adopted Medicare's rules and policies, so ensure you are familiar with each payer's rules.   

For the 2017 CERT report period, the improper payment rate for ventilators was 57.4 percent, with medical necessity errors for ventilators accounting for 58 percent of improper payments. For the purpose of the article in 2017, there were two HCPCS codes used to report home ventilators.

E0465 - Home ventilator, any type, used with invasive interface, (e.g., tracheostomy tube)

E0466 - Home ventilator, any type, used with non-invasive interface, (e.g., mask, chest shell)

The following is found in the NCD National Coverage Determination (NCD) for Durable Medical Equipment (DME) Reference List (280.1). 

Medical necessity errors for ventilators accounted for 58 percent of improper payments. In other words, 58 percent of payment errors on ventilators were recovered due to providers' documentation failing to document treatment of beneficiaries with one of the following conditions or failed to indicate the ventilator was required to treat at least one of the three medical conditions listed.

Ventilators

Covered for treatment of neuromuscular diseases,

thoracic restrictive diseases,

and chronic respiratory failure consequent to chronic obstructive pulmonary disease.  

Includes both positive and negative pressure types.

Artificial Intelligence in Healthcare - A Medical Coder's Perspective
December 26th, 2023 - Aimee Wilcox
We constantly hear how AI is creeping into every aspect of healthcare but what does that mean for medical coders and how can we better understand the language used in the codeset? Will AI take my place or will I learn with it and become an integral part of the process that uses AI to enhance my abilities? 
Specialization: Your Advantage as a Medical Coding Contractor
December 22nd, 2023 - Find-A-Code
Medical coding contractors offer a valuable service to healthcare providers who would rather outsource coding and billing rather than handling things in-house. Some contractors are better than others, but there is one thing they all have in common: the need to present some sort of value proposition in order to land new clients. As a contractor, your value proposition is the advantage you offer. And that advantage is specialization.
Changes to COVID-19 Vaccines Strike Again
December 12th, 2023 - Aimee Wilcox
According to the FDA, CDC, and other alphabet soup entities, the old COVID-19 vaccines are no longer able to treat the variants experienced today so new vaccines have been given the emergency use authorization to take the place of the old vaccines. No sooner was the updated 2024 CPT codebook published when 50 of the codes in it were deleted, some of which were being newly added for 2024.
Updated ICD-10-CM Codes for Appendicitis
November 14th, 2023 - Aimee Wilcox
With approximately 250,000 cases of acute appendicitis diagnosed annually in the United States, coding updates were made to ensure high-specificity coding could be achieved when reporting these diagnoses. While appendicitis almost equally affects both men and women, the type of appendicitis varies, as dose the risk of infection, sepsis, and perforation.

Medicare Guidance Changes for E/M Services
October 11th, 2023 - Wyn Staheli
2023 brought quite a few changes to Evaluation and management (E/M) services. The significant revisions as noted in the CPT codebook were welcome changes to bring other E/M services more in line with the changes that took place with Office or Other Outpatient Services a few years ago. As part of CMS’ Medicare Learning Network, the “Evaluation and Management Services Guide” publication was finally updated as of August 2023 to include the changes that took place in 2023. If you take a look at the new publication (see references below),....
Can We Score Interpretation of an EKG Towards E/M Medical Decision Making?
October 10th, 2023 - Aimee Wilcox
When EKGs are performed in the facility setting or even in the physician's office, what are the requirements for reporting the service and who gets credit for scoring data points for Evaluation and Management (E/M) medical decision making (MDM)? Let's take a look at a few coding scenarios related to EKG services to get a better understanding of why this can be problematic.
