Documentation requirements
From A52521
In addition to policy specific documentation requirements, there are general documentation requirements that are applicable to all DMEPOS policies. These general requirements are located in the DOCUMENTATION REQUIREMENTS section of the LCD. Refer to the LCD-related Standard Documentation Requirements article, located at the bottom of this Policy Article under the Related Local Coverage Documents section for additional information regarding GENERAL DOCUMENTATION REQUIREMENTS and the POLICY SPECIFIC DOCUMENTATION REQUIREMENTS discussed below. When the prescribing practitioner is also the supplier, and is permitted to furnish specific items of DMEPOS, a separate order is not required; however, the medical record must still contain all of the required order elements.

CONTINUED MEDICAL NEED For all DMEPOS items, the initial justification for medical need is established at the time the item(s) is first ordered, therefore, beneficiary medical records demonstrating that the item is reasonable and necessary are created just prior to, or at the time of, the creation of the initial prescription.
From A55426, Standard Documentation Requirements for All Claims Submitted to DME MACs

In addition to policy specific documentation requirements, there are general documentation requirements that are applicable to all DMEPOS policies. These general requirements are located in the DOCUMENTATION REQUIREMENTS section of the LCD. Refer to the LCD-related Standard Documentation Requirements article, located at the bottom of this Policy Article under the Related Local Coverage Documents section for additional information regarding GENERAL DOCUMENTATION REQUIREMENTS and the POLICY SPECIFIC DOCUMENTATION REQUIREMENTS discussed below. For quantities of supplies that exceed the usual maximum amount, there must be information in the medical record that explains the need for the increased amount. This information must be available upon request. Claims for tape and adhesive (A4450, A4452, A5120) that are billed without an AU modifier or another modifier indicating coverage under a different policy will be rejected as missing information. CONTINUED MEDICAL NEED For all DMEPOS items, the initial justification for medical need is established at the time the item(s) is first ordered, therefore, beneficiary medical records demonstrating that the item is reasonable and necessary are created just prior to, or at the time of, the creation of the initial prescription. Once initial medical need is established, ongoing need for ostomy supplies is assumed to be met.
