SNF Part B Billing Documentation and Audit Readiness Hub
What a complete claim file contains
- A standard written order signed by the treating practitioner and communicated before delivery.
- A contemporaneous clinical record establishing that the item meets the reasonable and necessary criteria in the applicable LCD.
- Proof of delivery confirming the item reached the resident.
- For recurring supplies, documented affirmative confirmation of continued need before the refill ships.
- Correct HCPCS code and unit calculation, retained with the file for seven years.

Standard written orders
The order names the item, the quantity, the frequency, and the treating practitioner, and it is signed and dated. It exists before the item is delivered. Orders that are back-dated, verbal-only, or missing the specific item are the single most common reason an otherwise valid claim cannot be defended on review.
Clinical notes that carry the medical necessity
The LCD sets the clinical criteria. The chart has to show those criteria in the resident's own record, contemporaneously, in the words of the clinician treating the condition. For surgical dressings that means wound characteristics and dressing change frequency. For urological supplies it means the qualifying condition, not just the device. Copy-forward notes that never change across weeks are a review flag.
Proof of delivery
Proof of delivery links the ordered item to the resident who received it, with a date. In a facility setting this is usually a signed delivery record or a documented internal receipt tied to the resident. Without it, the order and the clinical note are not enough.
Refill confirmation for recurring supplies
Recurring items require documented confirmation that the resident still needs the supply, obtained before the refill ships rather than after. Automatic recurring shipments with no contemporaneous confirmation are one of the clearest patterns reviewers look for.
Coding and units
The right code with the wrong unit count fails the same way a missing order does. Units follow the code's definition, not the package quantity. Quantity limits in the LCD apply, and exceeding them requires documentation explaining why.
Keeping the file audit-ready
Assemble the claim file at the time of billing rather than reconstructing it when a review letter arrives. A packet that pairs the order, the supporting clinical note, the delivery record, and the refill confirmation for each date of service is what a Targeted Probe and Educate response needs, and it is much cheaper to build once than to rebuild under a deadline.

Frequently asked questions
- Each claim should have a standard written order signed before delivery, a contemporaneous clinical note establishing medical necessity under the applicable LCD, proof of delivery, and, for recurring items, refill confirmation obtained before shipment. Keep all four together with the coding detail.
- Seven years from the date of service is the standard retention expectation for Medicare supply documentation.
- Patterns rather than single claims: unusual utilization for a category, high denial rates, or billing that looks different from peers. Reviews request the supporting documentation for a sample of claims, which is why the claim file matters more than the claim form.
- No. A signed standard written order communicated before delivery is what a reviewer expects to see. A verbal order that is never converted to a signed order leaves the claim undefendable.
- They can. Notes that are identical week over week do not demonstrate ongoing medical necessity for a changing condition, and reviewers treat that as a weak record even when the underlying care was appropriate.
- The party billing the claim needs the delivery evidence in its file. When the facility bills under its own NPI, that record should live with the facility's claim documentation.
