UB04 Condition Codes Code 39: Private Room Medically Necessary

Overview

According to the Noridian Condition Codes reference, this code is specifically designated as "Not used by PPS Hospitals" ^[1].

It is part of the broader Condition Code set (codes 01-79) that providers use to convey special circumstances affecting billing, payment, or coverage. The MassHealth UB-04 Billing Guide notes that condition codes are used to "special circumstances that affect billing or payment" and must be entered in Fields 18-28 of the claim form ^[2].

When to Use

Condition Code 39 should be used when a patient requires a private room due to documented medical necessity, not personal preference. The code is not appropriate for situations where the private room is requested for comfort, privacy, or convenience reasons.

Providers should note that Code 39 is explicitly "Not used by PPS Hospitals" ^[1]. This means that hospitals paid under the Medicare Inpatient Prospective Payment System (IPPS) generally cannot use this condition code to justify private room charges beyond the standard DRG payment. However, non-PPS facilities such as critical access hospitals, psychiatric hospitals, rehabilitation facilities, or skilled nursing facilities may use this code when billing for medically necessary private rooms. The code should be supported by physician orders and clinical documentation in the medical record stating the medical reason for the private room accommodation.

Step-by-Step Claim Example

Scenario: A 72-year-old patient is admitted to a non-PPS psychiatric facility with a diagnosis of severe depression and active pulmonary tuberculosis. The facility places the patient in a private room for airborne infection isolation (necessary for TB management).

Step 1: Complete Claim Header Information Enter the facility name, address, provider number, and patient demographics in Fields 1-12 of the UB-04 as per standard submission requirements.

Step 2: Enter Condition Code in Field 18-28 In the Condition Code fields (18-28), enter "39" as the first condition code. If other condition codes apply, list them sequentially in these fields ^[2]. For example, Code 39 might appear in Field 18 with other applicable codes in subsequent fields.

Step 3: Complete Revenue Codes (Field 42) In the revenue code section, report the appropriate revenue code for room and board. For a private room, use Revenue Code 0140 (Private Room) or 0141 (Medical/Surgical Private) depending on the facility type. The reimbursement amount for the private room should reflect the medically necessary accommodation charges ^[2].

Step 4: Attach Supporting Documentation Include the physician order for private room, isolation order, and clinical notes documenting the medical necessity (e.g., "Patient requires private room for airborne infection isolation due to active pulmonary TB"). This documentation should be maintained in the medical record and available for audit review.

Step 5: Submit the Claim Ensure all fields are completed correctly, including provider information, patient data, dates of service, and diagnosis codes (ICD-10 codes for TB and depression). Submit electronically or on paper as required by the payer. The MassHealth guide notes that most claims must be submitted electronically unless a waiver is obtained ^[2].

Common Mistakes & Audit Red Flags

Using code 39 for non-medical reasons: The most frequent error is billing Code 39 when the private room was requested for patient comfort, family convenience, or personal preference without a documented medical necessity. Auditors will request physician orders and clinical notes justifying the private room ^[1].

Applying code to PPS hospitals: Another critical mistake is using Code 39 in PPS hospitals where it is explicitly not allowed. The Noridian reference clearly states the code is "Not used by PPS Hospitals" ^[1]. Using it incorrectly may trigger claim denials or recoupment.

Incomplete documentation: Providers frequently fail to document the specific medical reason for the private room in the medical record. For isolation cases, the type of infection and required precautions must be documented. For immunocompromised patients, the underlying condition and risk factors should be noted.

Billing private room charges separately: Some providers attempt to bill private room charges as a separate line item above the standard semi-private room rate. This is only appropriate when medical necessity is clearly documented and when the facility's payment model allows such separate billing. The MassHealth guide emphasizes that accurate completion of revenue codes is essential ^[2].

Audit red flags include: Multiple claims with Code 39 from the same facility without corresponding infection control documentation, high volumes of private room billing for certain providers, and discrepancies between private room charges and documented isolation orders.

The table above shows related codes from the UB-04 condition code set and revenue codes. All condition codes listed (37, 38, 39) are designated as "Not used by PPS Hospitals" in the Noridian reference material ^[1]. Providers should verify proper code pairing with revenue codes per their specific payer's guidelines ^[2].
