Billing and Coding: Hydration Services

Noridian Medical Review (MR) has observed errors in billing for intravenous
(IV) hydration services. This article is to assist in better understanding the
proper usage of the below codes for billing and coding purposes.

**CPT Definition: **

  * 96360: Intravenous Infusion, hydration; initial, 31 minutes to 1 hour
  * 96361: Intravenous Infusion, hydration; each additional hour (list separately in addition to code for primary procedure)

These codes are intended to report a hydration IV infusion consisting of pre-
packaged fluid with or without electrolytes (e.g. normal saline, D5-1/2 normal
saline+30mEq KCl/liter) and are not used to report infusion of drugs or other
substances.

**Hydration Defined:**

The hydration codes 96360 and 96361 were developed to report specific
therapeutic interventions undertaken when a patient presents with dehydration
and volume loss requiring clinically necessary intravenous fluid.

  1. The necessity for hydration should be supported in the medical record.

**Documentation would include but is not limited to:**

A. Clinical assessment, typically on the same date of service, of the
patient's anticipated fluid needs. This can be demonstrated from the patient's
history, clinical examination, and pertinent laboratory testing to support the
need for IV hydration therapy as reasonable and necessary for the patient's
treatment or diagnosis.

  1.     1. Documentation of the assessment should describe symptoms warranting hydration, such as those associated with dehydration, the inability to ingest fluids or clear clinical contraindication to oral intake, abnormal fluid losses, abnormal vital signs, and/or abnormal laboratory studies, such as an elevated BUN, creatinine, glucose or lactic acid.
    2. Nausea itself does not necessarily indicate fluid volume depletion nor support necessity of fluid repletion.

B. These codes are not intended to be reported/billed by the physician or
other qualified healthcare professional in the facility setting, as these
codes most likely represent facility charges with applicable reimbursement
through the respective fee schedule. However, in the physician _office_
setting (example, Place of Service 11), the physician may report these codes
when the physician's clinical staff or the physician administers the fluids.

C. For _facility_ reporting, an initial infusion is predicated on using a
hierarchy.

D. When administering multiple infusions (e.g. IV fluids and subsequent IV
chemotherapy infusion on same date of service), only one primary infusion code
should be reported for a given date, unless protocol requires that two
separate IV sites must be used.

E. Hydration cannot be reported _concurrently_ with any other infusion or drug
administration service.

F. The definition of infusion time is inherent and presented in the guidelines
for these codes. In other words, a minimum time duration of 31 minutes of
hydration infusion is required to report the service.

G. Consequently, infusion time is calculated from the time the administration
commences (i.e. the infusion starts dripping) to when it ends (i.e. the
infusion stops dripping).

H. In accordance with **Medicare Reasonable and Necessary Criteria** ,
**(Medicare Program Integrity Manual, Chapter 3, Section 3.6.2.2)** , the
benefit must meet but **does not exceed** the beneficiary's medical need, and
as such, IV fluids should be avoided if not deemed clinically necessary.

  1. For example, although some conditions may warrant intravenous rehydration, if documentation supports the same benefit could be achieved by oral hydration, IV hydration would not be considered reasonable and necessary.
  2. However, it is understood that there are clinical scenarios in which the patient's need for hydration cannot wait for oral trials, even if an option. The intent should be understood within the body of documentation.

I. **Examples** **of Additional Payable Scenarios:**

  1. If therapeutic fluid administration is medically necessary:

  1.     1. for the correction of dehydration or prevention of nephrotoxicity immediately before or after transfusion, chemotherapy, or administration of potentially nephrotoxic medications.
    2. immediately before or after IV contrast infusion for a diagnostic procedure in a patient with renal insufficiency.

J. **Non-payable scenarios :** The following infusion circumstances **do not
represent hydration** and should not be reported using any of these CPT codes:

  1. If the sole purpose of the intravenous fluid is to maintain patency (i.e. keep open) of an IV line prior to, during, or subsequent to a chemotherapeutic or therapeutic infusion, or transfusion.
  2. If used as "maintenance" IV therapy replacing normal sensible and insensible fluid losses, not losses associated with a pathological condition.
  3. When the purpose of the infusion is to accommodate a therapeutic IV piggyback through the same IV access to safely infuse the agent (e.g. IV fluids infused simultaneously with drug administration).
  4. If the fluid is used as the diluent to mix the drug (i.e. the fluid is the vehicle in which the drug is administered).
  5. Hydration that is integral to the performance of a surgical procedure to establish an initial and underlying IV flow for a diagnostic or therapeutic infusion is not separately billable (e.g. IV fluids administered preoperatively, intraoperatively, and/or postoperatively).
  6. Routine administration of IV fluids, pre/post operatively while the patient is NPO for example, without documentation supporting signs and/or symptoms including those of dehydration or fluid loss is not supported as medically necessary.
  7. Infusion of IV fluids with electrolytes for the purpose of treating an electrolyte deficiency (e.g. hypokalemic patient being treated specifically for low potassium level for which 20 mEq of KCL is added to an IV fluid).

In conclusion, the **main question that should be asked when considering
billing for 96360 and 96361 is whether IV hydration is an appropriate,
accepted standard of medical practice as a diagnostic or specific treatment
for a beneficiary 's condition,is one that meets, BUT does NOT exceed the
beneficiary's medical need, and cannot be met with oral hydration.**

_**Note:** It is understood that depending on the clinical scenario, upon
presentation, an IV line may be established, fluids initiated, labs drawn and
sent for evaluation and imaging completed with examinations. Although it may
be reasonable to start fluids upon presentation, in order to bill the IV
hydration codes, the medical necessity for the hydration services must also be
supported. If the final clinical assessment does not support intravenous
hydration was necessary for beneficiary's medical needs, hydration codes
should not be billed_
