For residential care

Why residential billing needs a different approach

A residential claim is not a single event at discharge. Authorisation, reviews of ongoing stay, documented days and payer specific charges accrue during the stay and any of them can delay payment.

Residential care, when it is provided outside of a hospital, is typically billed on a per diem rather than per visit basis. What codes are used? What claim form is used? What are the review rules? These decisions are made by the payer, the licence, the setting, and the contract.

We help your team keep approvals, billable days and claims data in line with the care that’s actually being delivered.

What’s different about residential claims

  • Per diem charges and counting of covered days
  • Reviews of admission and continued stay
  • Documentation of medical necessity and level of care criteria
  • Code, claim type and authorisation dates match
  • Out of network language, denials and short payments
  • Separate rules for mental health and substance use disorders
Where home claims stall

Residential billing problems

Concurrent review deadlines, non-billable days and changing payer criteria require consistent, payer-by-payer oversight.

01

Authorisations and continued-stay reviews

An admission approval is only for named days. We track dates, requests and payer decisions; because one missed review or thin clinical update can put the next stretch of days at risk.

02

Level-of-care denials

Payers may use ASAM criteria, LOCUS, CALOCUS-CASII, or their own. We find documentation gaps and coordinate appeals. Clinicians maintain all care decisions.

03

Per-diem and billable-day errors

All rates, authorised days, admit and discharge dates, and leave or pass days must match the payer’s rules. A day off can change what you get paid.

04

Codes, Forms, and Revenue Codes

Some payers require a UB-04 (837I) with revenue codes such as 1001 for psychiatric or 1002 for chemical dependency residential care. Others require a CMS-1500 (837P). Mismatch with the authorisation delays the payment.

05

Out-of-network stays and single case agreements

We assist with agreement requests, payer paperwork and follow-up on claims. Approval and the rate are determined by the payer.

06

Partial denials and ageing A/R

We compare remittances to authorised days and contract rates. We then rank open balances by payer response, claim size and deadline.

What we deal with

Billing Services for Residential Treatment Facilities

Tailor the revenue cycle segments you want covered to your program and payer mix.

01

Benefits and Insurance Coverage

Before admission, verify residential benefit, patient cost share, authorisation requirements, and plan limitations. Payment not guaranteed upon verification.

02

Concurrent Reviews & Authorisation

Monitor approved dates, authorisation numbers, review deadlines and payer requests in the agreed scope of services.

03

Coding and claim preparation daily

Verify the billed method, HCPCS or revenue codes, units and covered days as approved by the payer. Depending on the contract, H0018, H0019 and T2048 may apply.

04

Claim Submission & Payer Follow-Up

Prepare claims with correct dates, codes and authorisations. Track rejections and responses from payers after claim submission.

05

Appeals and Denial Management

Research technical denials and level-of-care disputes, collect supporting records, and coordinate appeals as needed.

06

Reconciliation and posting of payments

Compare paid days, contract rates, remittances and adjustments to identify discrepancies for review.

07

Residential AR Call Back

Track ageing balances, payer status, follow-up actions and appeal due dates so that open claims do not go dark.

08

Revenue Cycle Reportings

Look at rejections, outstanding balances, authorisations shortfalls and recurring payer problems that are part of the project’s reporting.

Programs we collaborate with

Programs for residential living

Billing rules are different for different populations served, different licenses held and different payers.

01

Mental Health Residential Treatment

Authorisation and continued stay records, to include LOCUS or other payer criteria that apply.

02

Substance use residential treatment

ASAM-based review where required, payer-specific billing and 42 CFR Part 2 handling of covered records.

03

Eating disorder residential programs

Coverage checks, level of care records, and claim filing methods that work for the payer and the program

04

Adolescent and young adult units

Benefit checks and authorisation rules for age specific, including Medicaid psych under 21 benefit where a state offers it, and commercial plans.

05

Dual-diagnosis residential

Documentation and claims related to mental health and substance use co-occurring disorders.

06

Residential with PHP or IOP step-down

Specific transition dates and billing rules that vary depending on the level of care.

Payer rules

Private coverage, Medicare and Medicaid

We review coverage, authorisation rules and claim requirements for each plan prior to billing.

Medicare

Original Medicare does not cover H or T codes, and has no benefit for non-hospital residential treatment. There are different rules for inpatient and outpatient psychiatric care. Some Medicare Advantage plans include extra benefits so it’s worth checking them out.

Medicaid

Covered services differ by plan and state, including codes, rates and authorisations. In general, adults ages 21 to 64 who are in an institution for mental diseases (a facility with more than 16 beds that primarily treats mental illness) are not covered by federal funds, but there are exceptions and state waivers.

Commercial Insurance

Plans may require admission certification, concurrent reviews, and specific clinical evidence. Network status and rules for single case agreements and billable days may vary, and some payers may require licensure and accreditation documents.

Current payer guidance and your facility contract apply to codes, forms and payment terms.

The documentation

Residential billing compliance & documentation

Complete records support authorisation reviews, accurate claims and appeals. The most important ones:

  • Dates of admission, discharge, and authorisation
  • Level of care assessments and treatment strategies.
  • Progress notes and services billed daily
  • Payer required physician involvement or certification.
  • Appeal files and letters from payers

42 CFR Part 2 records for substance use have confidentiality rules that exceed HIPAA, so check consent and disclosure terms with your compliance team before sending them out for billing.

We flag gaps in records related to billing. Your providers and compliance staff retain responsibility for clinical decisions and regulatory oversight.

What program managers should know

FAQs on residential treatment billing

Brief answers for coverage, codes, authorisation and records.

1. What do residential treatment billing services cover?

They may include benefit checks, authorisation tracking, per diem claim preparation, submission, denials, posting, reporting and A/R follow-up, depending on the agreed scope.

2. What is the difference between inpatient and outpatient billing?

Outpatient claims are per encounter. Non-hospital based residential care is typically billed on a per diem basis and has different payer, record and claim rules.

3. What is per diem billing in residential care?

Each eligible day is billed based on the payer’s contracted methodology. Check rates, codes, units, dates of admission and discharge, leave-day rules.

4. What are H0018, H0019 and T2048?

H0018 is a per diem code for short term non-hospital residential treatment and H0019 is for long term residential treatment, usually stays over 30 days. Both exclude room and board. T2048 describes long term care with room and board included. States and payers decide which of these codes to accept, and Medicare does not pay them.

5. Why are claims denied after they have been authorised?

Authorisations have time limits and level of care limits. Even if you miss a continued stay review, have a documentation gap, or bill days and codes that don’t match the approval, the claim can still be denied.

6. Is non-hospital residential treatment covered by Medicare?

Original Medicare does not have a separate benefit for this. There are separate rules for psychiatric inpatient and outpatient benefits. Medicare Advantage extras vary by plan and must be verified .

7. What impact does Medicaid have on residential claims?

Covered services and billing rules are determined by states and managed care plans. Changes in coverage can occur due to the IMD exclusion for adults 21-64, its exceptions and state waivers, with the psych under 21 benefit being available to younger patients when a state provides it.

8. Do you assist with out of network residential claims?

We can assist with administrative single case agreement requests, payer follow-up and claims review. Terms of approval and payment are at the discretion of the payer.

42 CFR Part 2 has a major effect on billing for substance use services. Additional rules apply to the confidentiality of covered treatment records. Your compliance team needs to verify consents and disclosures for billing partners and payers.
