Billing Code Overview

HCPCS Level II code G0299 describes direct skilled nursing services provided by a registered nurse (RN) in the home health or hospice setting, billed in 15-minute increments. The service type is skilled nursing – home health or hospice and the typical site of service is a home health or hospice environment (for example, POS 12 or relevant revenue code 055x).

Clinical Context

A homebound patient with multiple chronic conditions receives direct skilled nursing care at home or in a hospice residence. For example, an elderly patient with heart failure (I50.9), chronic obstructive pulmonary disease (J44.9), and type 2 diabetes (E11.9) who is largely bed-confined (Z74.01) is followed after recent hospital discharge for ongoing wound checks, medication management, intravenous or subcutaneous therapy administration, and clinical assessment during an aftercare encounter (Z48.89). A registered nurse (RN) travels to the patient’s place of residence (Home Health or Hospice - POS 12 or relevant revenue code 055x) and provides direct skilled nursing interventions in discrete 15-minute units, documenting time, skilled interventions performed, clinical findings, and plan of care updates. The RN documents medical necessity for each 15-minute unit of service, the specific skilled tasks performed (for example, wound care, injections, clinical assessment), and communicates changes to the supervising clinician or home health agency.

Coding Specifications

• HCPCS Level II code G0299: Direct skilled nursing services of a registered nurse (RN) in the home health or hospice setting, each 15 minutes.

• Common Modifiers

• TT — Individualized service provided to more than one patient in the same setting: used when the same skilled RN service is delivered to multiple patients in a group setting but the service is individualized to each patient; appended to reflect that the service was furnished under this circumstance.

• 59 — Distinct Procedural Service: used when the RN provides a service that is separate and independent from other services delivered on the same day and requirements for separate reporting are met.

• Provider Taxonomies (Associated specialties)

• 163WH0200X — Home Health Registered Nurse: RN specialty practicing in home health settings.

• 251E00000X — Home Health Agency: organizational taxonomy for agencies providing home health services.

• 163W00000X — Registered Nurse: general RN taxonomy covering licensed nursing professionals who may provide skilled services in home or hospice settings.

Related Diagnoses

• Z74.01 — Bed confinement status

  Clinical relevance: Indicates the patient is largely confined to bed, supporting the need for in-home skilled nursing services such as monitoring, repositioning support, and interventions that can be billed in 15-minute RN units.

• Z48.89 — Encounter for other specified aftercare

  Clinical relevance: Represents post-hospital or post-procedural aftercare encounters during which skilled RN services (wound checks, medication administration, assessment) are commonly provided in the home or hospice setting.

• I50.9 — Heart failure, unspecified

  Clinical relevance: Heart failure patients often require skilled nursing assessment, medication titration, and monitoring at home, justifying skilled RN visits billed with 15-minute units.

• J44.9 — Chronic obstructive pulmonary disease, unspecified

  Clinical relevance: COPD exacerbations and chronic management may require skilled nursing observation, inhaled medication administration, oxygen assessment, and education, supporting RN time billed per 15-minute unit.

• E11.9 — Type 2 diabetes mellitus without complications

  Clinical relevance: Diabetes management in the home (insulin administration, foot/wound care, monitoring) can require skilled RN hands-on services that are billed in 15-minute increments.

Related Codes

• G0300 — Direct skilled nursing services of a licensed practical nurse (LPN) in the home health or hospice setting, each 15 minutes. This is the LPN counterpart to HCPCS Level II code G0299; used when a licensed practical nurse rather than an RN provides the 15-minute skilled nursing service.

• G0162 — Skilled services by a licensed nurse (RN only) for management and evaluation of the plan of care, each 15 minutes. Used for RN time focused on plan-of-care management and evaluation; may be used in conjunction with or as an alternative when the primary service is plan-of-care management rather than direct hands-on interventions.

• G0493 — Skilled services of a registered nurse (RN) for the observation and assessment of the patient’s condition, each 15 minutes. This emphasizes observation/assessment; may be billed with G0299 for distinct assessment encounters or used as an alternative when assessment is the primary skilled function.

• G0494 — Skilled services of a licensed practical nurse (LPN) for the observation and assessment of the patient’s condition, each 15 minutes. LPN equivalent to G0493 and related to G0300 as the LPN observation/assessment code.

• G0495 — Skilled services of a registered nurse (RN), in the training and/or education of a patient or family member, in the home health or hospice setting, each 15 minutes. Relates to G0299 when the RN’s skilled time is primarily education/training rather than direct clinical procedures.

• G0496 — Skilled services of a licensed practical nurse (LPN), in the training and/or education of a patient or family member, in the home health or hospice setting, each 15 minutes. LPN counterpart to G0495.

• Common usage notes: G0300, G0494, and G0496 are LPN-level equivalents; G0162, G0493, and G0495 represent RN services with different emphases (management/evaluation, observation/assessment, and education respectively). These codes are commonly considered together when documenting the specific skilled nursing activity performed during a home health or hospice visit; selection depends on the primary skilled function rendered during each 15-minute unit.

National mean rates for HCPCS Level II code G0299 show a wide split between Medicare and average commercial payers: BUCA (average commercial) reports a mean of $77.22 while Medicare is not provided in the input (reported here as $0.00 for clarity). Cigna Health reports the highest reported commercial mean at $163.72.

Rate dispersion varies notably by payer. Cigna Health and UnitedHealthcare have very tight distributions (Cigna: P75–P25 = 0; UnitedHealthcare: P75–P25 = 0), while BUCA (Avg Commercial) shows the widest spread (P75–P25 = 91), followed by Blue Cross Blue Shield (P75–P25 = 37). Aetna’s distribution is also tight (P75–P25 = 17). The table and chart below present the full numeric breakdown.
