Important Home Health HCPCS Codes

Home Health HCPCS Code

Last Updated on October 29, 2025

Home health reimbursement depends on choosing the correct service line for the care delivered, discipline, clinician type, visit intent (restorative vs. maintenance), time, and setting must all map cleanly to the claim. When that mapping is consistent, PDGM logic behaves, edits drop, and payments land on the first pass. This guide distills the small set of Home Health HCPCS items HHAs use every day and explains how to select the right one in real-world scenarios. Use it to standardize choices across your team, reduce avoidable rework, and keep cash flow predictable.

How Home Health Is Billed?

Home health agency claims are submitted on the UB-04 (TOB 032X/034X). Each claim reports HCPCS service codes, primarily G-codes, paired with the correct revenue codes, includes a 0023 HIPPS line for grouping and payment, identifies the care setting with a Q500x site-of-service code, and lists Value 61 (CBSA) along with any required value, condition, or occurrence codes. CPT generally applies to physician/APP professional claims rather than HHA facility billing, so this guide focuses on the HCPCS elements home health teams use every day.

1) Nursing & Clinical Disciplines 

These lines capture who furnished the service (RN/LPN/PT/OT/SLP/aide), what was delivered (restorative vs maintenance), and how much (timed units). Accuracy here drives PDGM logic, LUPA risk, and medical-necessity validation.

HCPCSWhat it captures
G0299Direct skilled nursing by RN
G0300Direct skilled nursing by LPN
G0151PT services, each 15 min
G0152OT services, each 15 min
G0153SLP services, each 15 min
G0155Clinical social worker, each 15 min
G0156Home health aide, each 15 min
G0157PTA services, each 15 min
G0158OTA services, each 15 min
G0159PT maintenance program, each 15 min
G0160OT maintenance program, each 15 min
G0161SLP maintenance program, each 15 min
G0162RN management & evaluation of plan of care, each 15 min
G0493RN observation/assessment, each 15 min
G0494LPN observation/assessment, each 15 min
G0495RN training/education, each 15 min
G0496LPN training/education, each 15 min

Documentation cues: Always make minutes traceable to skilled need, goals, and response. Distinguish restorative vs maintenance therapy in the note.

2) Telecommunication & Remote Collection

Use these when policy allows to document clinically necessary non–face-to-face encounters or physiologic data capture. They supplement in-person care; they don’t satisfy visit thresholds and require modality, purpose, and linkage to the plan of care.

HCPCSWhat it captures
G0320HHA services via real-time audio-video
G0321HHA services via interactive audio-only
G0322Collection of physiologic data / RPM by HHA

These are tracking/reporting codes. They don’t replace in-person visit thresholds for PDGM/LUPA. Document clinical purpose + modality.

3) Physician/APP Codes Tied to the Home Health Plan

These are billed by the certifying/overseeing provider, not the HHA. They substantiate plan initiation, recertification, and ongoing oversight, aligning episode timing and documentation with payer requirements.

HCPCSWhat it captures
G0180Certification of HHA plan of care (initial episode)
G0179Recertification of HHA plan of care
G0181Care Plan Oversight (CPO) for patients under HHA services

HHAs coordinate these documents; billing for them is by the physician/APP.

4) Q500x: Site-of-Service

This element declares where services occurred (home, ALF, other) and must reflect the actual setting at the time of care. Correct selection impacts payment jurisdiction, edits, and audit defensibility.

HCPCSLocation
Q5001Patient’s home/residence
Q5002Assisted living facility
Q5009Other/Not otherwise specified location

Using the right Q500x code is one of the simplest ways to avoid preventable edits.

5) UB-04 Companions You Can’t Ignore

These fields bind the claim together: revenue lines must align with service intent, the HIPPS line enables grouping/payment, and value/condition/occurrence codes supply geography and event context. Small mismatches here commonly trigger RTPs/denials.

Revenue codes (common for HH):

  • 042X PT, 043X OT, 044X SLP
  • 055X Skilled nursing, 056X Social work, 057X HHAide
  • 027X/062X Medical/surgical supplies (e.g., 0623 surgical dressings)
  • 060X Oxygen, 029X DME (other than rental)
  • 0001 Total charges, 0023 HIPPS line

Value/Condition/Occurrence (frequent):

  • Value 61 = CBSA where services provided (required on 32X)
  • Condition: 20 demand denial, 21 no-pay bill, 47 HHA transfer, 54 no skilled visits (policy exception), DR disaster-related
  • Occurrence: 55 date of death (pair with PDS 20)

Patient Discharge Status (commonly seen): 01, 06, 07, 20, 30, 50, 51

6) Modifiers You’ll Actually Use

Modifiers disclose who participated (e.g., assistants), why coverage criteria are met, or how medical-necessity was handled. Apply only when rules are satisfied and ensure the note explicitly supports their use to avoid recoupment.

  • CQ / CO — Services furnished in whole or in part by PTA/OTA (apply per assistant rules, minutes, supervision).
  • KX — Requirements/medical-necessity criteria met (use only when policy requires).
  • GA / GY / GZ — ABN/medical-necessity family (apply carefully, per payer).

Assistant involvement must be obvious in the note (plan, tasks, minutes). If assistants furnished care that triggers CQ/CO, the modifier belongs on the line.

Clean-Claim Checklist

  • 0023 HIPPS line present and correct
  • Revenue codes align with the HCPCS service lines
  • Q500x location selected correctly (home vs ALF vs other)
  • Value 61 (CBSA) present and accurate
  • Patient Discharge Status matches chart
  • MSP screened and value codes completed when applicable
  • Minutes & modality supported in notes; restorative vs maintenance clear
  • CQ/CO added when assistants furnished care (and documentation supports it)
  • Telecom G-codes (G0320–G0322) used only as allowed, with purpose/modality documented

Need fewer edits and faster pay?

We keep the daily fundamentals tight, correct G-codes, HIPPS mapping, Q500x/Value 61 accuracy, assistant modifiers, and MSP checks, so your claims pass the first time.

FAQs in Home Health

1. Do I ever use CPT on an HHA facility claim?

No. HHA facility claims on UB-04 032X or 034X report HCPCS. CPT appears on professional claims such as physician or APP billing, not on the HHA’s UB-04.

2. What is the quickest way to pick the right nursing or therapy code?

Ask three things: who furnished it (RN, LPN, PT, OT, SLP, aide), what was done (direct care, assessment or education, or maintenance), and how much time. Then map to the correct G code and revenue code.

3. G0299 vs G0493 what is the difference in plain terms?

G0299 and G0300 are direct skilled nursing by RN or LPN. G0493 through G0496 are observation or assessment or training or education by RN or LPN, reported in 15 minute units.

4. When should I use the maintenance program codes G0159 to G0161?

Use maintenance codes when the plan requires ongoing skilled involvement to maintain function or prevent decline. The note must explain why skilled maintenance is needed and what the clinician did.

5. Do assistant services require special indicators?

Yes. If a PTA or OTA furnishes services and payer rules require disclosure, append CQ for PTA or CO for OTA. Documentation must show plan alignment, supervision, and minutes attributable to the assistant.

6. Do telecommunication codes replace in person visits?

No. Telecommunication and remote data collection HCPCS do not satisfy in person visit thresholds. Use only when allowed and document modality and clinical purpose.
