UB04 Condition Codes Code 73: Self-care Training

Overview

Condition Code 73, “Self-care training,” is a UB‑04 condition code used specifically for dialysis patients who are receiving training to perform self‑dialysis. According to the Noridian Condition Codes list, code 73 is defined as “Self‑Care training (dialysis).” ^[1] This code falls within a block of dialysis‑related condition codes (70–77) that describe various dialysis settings and services, such as self‑administered EPO, full care in a unit, self‑care in a unit, home dialysis, and backup dialysis. ^[1] The code is entered in fields 18–28 of the UB‑04 claim form, where condition codes are reported to convey special circumstances about the patient’s episode of care. The MassHealth UB‑04 Billing Guide confirms that condition codes are part of the standard code sets used on the UB‑04 form. ^[2] Proper use of code 73 ensures that the training services are correctly identified for billing and reimbursement purposes, particularly under Medicare and other payers that recognize this specific dialysis training indicator.

When to Use

Condition Code 73 should be used when a dialysis patient is undergoing training to learn how to perform self‑dialysis, typically in a home setting. The training is intended to prepare the patient to manage their own dialysis treatments without direct assistance from facility staff. ^[1] This code is distinct from code 72 (“Self‑Care in unit (dialysis)”), which indicates that the patient is already performing self‑care in a facility, and from code 74 (“Billing is for a patient who received dialysis services at home”), which applies after training is complete and the patient is dialyzing at home. ^[1] Providers should apply code 73 only during the training period, not for ongoing maintenance dialysis. The code may be used in conjunction with other condition codes, such as code 70 (self‑administered EPO) or code 76 (backup dialysis in‑facility), if applicable. ^[1] It is important to verify payer‑specific requirements, as some insurers may require additional documentation or prior authorization for self‑care training services. Using code 73 correctly helps ensure that the training is recognized as a distinct, billable service and that the claim is processed without unnecessary delays or denials.

Step‑by‑Step Claim Example

Consider a Medicare patient with end‑stage renal disease (ESRD) who is enrolled in a home dialysis training program at a hospital‑based dialysis center. The training spans five sessions over two weeks. On the UB‑04 claim for the training sessions, the provider enters Condition Code 73 in one of the condition code fields (fields 18–28). ^[1] The claim also includes the appropriate revenue codes for dialysis training (e.g., revenue code 0821 for home dialysis training) and the corresponding HCPCS code for the training service. The patient’s primary diagnosis is ESRD (ICD‑10‑CM N18.6). The provider ensures that no other dialysis condition code (such as 72 or 74) is used simultaneously, because the patient is still in training and not yet performing self‑care independently. ^[1] After the training is completed, subsequent claims for home dialysis would use Condition Code 74 instead. The claim is submitted electronically or on paper (if a waiver is obtained) following the instructions in the MassHealth UB‑04 Billing Guide. ^[2] The payer processes the claim, recognizing code 73 as an indicator that the services are for self‑care training, and applies the appropriate reimbursement rules for dialysis training.

Common Mistakes & Audit Red Flags

One frequent mistake is using Condition Code 73 for any type of self‑care training that is not related to dialysis. The Noridian list explicitly limits code 73 to “Self‑Care training (dialysis).” ^[1] Using it for training in other self‑care activities (e.g., wound care, insulin administration) will likely result in claim denial or audit findings. Another error is applying code 73 after the patient has already completed training and is performing self‑dialysis at home; in that scenario, code 74 should be used instead. ^[1] Auditors also look for inconsistent use of dialysis condition codes—for example, billing code 73 alongside code 72 (self‑care in unit) on the same claim, which may indicate a coding conflict. Additionally, providers sometimes omit code 73 when training is provided, leading to under‑reporting of training services and potential revenue loss. To avoid red flags, ensure that the condition code matches the service period and that supporting documentation (e.g., training records, patient education notes) is maintained. Finally, verify that the revenue code and HCPCS code align with the condition code; mismatched codes can trigger medical review.

Related Codes/Fields

Condition Code 73 is part of a family of dialysis‑related condition codes (70–77) reported in fields 18–28 of the UB‑04 form. The table below lists these codes and their meanings as provided by Noridian. ^[1]

Condition Code	Meaning
70	Self‑administered EPO (home dialysis)
71	Full care in unit (dialysis)
72	Self‑Care in unit (dialysis)
73	Self‑Care training (dialysis)
74	Billing is for a patient who received dialysis services at home
75	Billing for home dialysis with machine purchased under 100% payment program
76	Back‑up dialysis in‑facility
77	Provider accepts primary payer payment as pa (partial)

These codes are mutually exclusive in most cases, though some combinations may be allowed (e.g., code 73 with code 70 if EPO is self‑administered during training). Providers should consult payer‑specific guidelines for proper sequencing and usage. The UB‑04 field 18–28 can accommodate up to 11 condition codes; code 73 should be placed in the earliest available field. ^[2] (The MassHealth guide references code sets but does not specify field numbers; standard UB‑04 instructions apply.)
