Is there a medical billing company near me in Baltimore that specializes in behavioral health?

Yes. Maryland Medical Billers is a Baltimore-based medical billing company that specializes in behavioral health, mental health, and therapy practice billing for providers across the Baltimore metro area, surrounding Maryland counties, and Washington DC.

How much does a medical billing service cost for a small therapy practice?

Maryland Medical Billers uses a performance-based pricing model, charging 6% to 8% of monthly collections rather than a flat fee. This means the billing company is paid only when the practice gets paid.

What is the difference between provider credentialing and insurance credentialing?

Provider credentialing verifies a clinician's qualifications, such as licensure and education, with payers and institutions. Insurance credentialing is the process of enrolling a provider with specific insurance networks, including CAQH attestation and ePREP enrollment, so claims can be reimbursed under that network.

Can a medical billing company help reduce claim denials for mental health practices?

Yes. A dedicated denial management process identifies the root causes of rejected claims, such as timely filing errors or incomplete credentialing, and resubmits corrected claims to improve first-pass rates and recover outstanding accounts receivable.

Why should a Maryland therapy practice outsource billing instead of handling it in-house?

Outsourcing billing to a specialized firm like Maryland Medical Billers gives small and mid-sized practices access to expertise in payer-specific rules, such as Carelon Behavioral Health of Maryland requirements, without the overhead of hiring and training in-house billing staff.

How to Navigate Carelon Behavioral Health of Maryland as a Provider

Carelon Behavioral Health of Maryland serves as the Administrative Services Organization for Maryland’s Medicaid behavioral health program. As an ASO, Carelon handles the administrative functions of Maryland’s Medicaid behavioral health benefits, including prior authorization, utilization management, and claims processing for behavioral health services provided to Maryland Medicaid enrollees. This is not a managed care arrangement where Carelon carries financial risk. It is an administrative arrangement where Carelon manages the operational side of behavioral health Medicaid while the Maryland Department of Health retains program oversight.

For Maryland behavioral health providers, understanding how Carelon operates, how to navigate its authorization system, and how to resolve Carelon denials is a foundational operational requirement rather than an advanced billing skill. This guide covers the key functions every Maryland behavioral health practice needs to understand about Carelon.

Who Interacts with Carelon and When

Every Maryland behavioral health provider billing Maryland Medicaid patients interacts with Carelon in some way. The specific interactions depend on the services provided:

Authorization functions. Carelon manages prior authorization for most behavioral health services billed to Maryland Medicaid, including outpatient individual therapy, group therapy, psychiatric evaluation, medication management, and higher levels of care. The authorization process goes through Carelon’s provider portal and requires clinical documentation supporting the service type and frequency requested.

Claims processing. Behavioral health claims for Maryland Medicaid patients do not route through the general Maryland Medicaid claims system. They route through Carelon’s claims processing system. Submitting a behavioral health Medicaid claim to the wrong pathway generates a rejection that requires resubmission through the correct system.

Provider network. Behavioral health providers serving Maryland Medicaid patients must be registered with Carelon in addition to enrolling in Maryland Medicaid through ePREP. Carelon registration is a separate process with its own application and approval timeline.

Utilization management. Carelon conducts utilization review for certain service types and levels of care. Requests for continued authorization for higher-level services may be subject to clinical review by Carelon’s utilization management team.

Carelon Authorization — What Maryland Providers Need to Track

Authorization tracking is the most operationally significant Carelon function for outpatient behavioral health practices. Every Carelon authorization has:

A service type specification (the type of service the authorization covers)
A session count (the number of sessions authorized)
An expiration date (the date after which new sessions are no longer covered under the authorization)
A rendering provider specification (the clinician authorized to provide the service)

For a practice in Howard County, Baltimore City, or Prince George’s County billing weekly therapy to multiple Medicaid patients simultaneously, managing these four elements for every active Medicaid patient simultaneously is a continuous administrative function.

The most common authorization errors that generate Carelon denials are:

Billing a session after the authorization expiration date without having renewed
Billing a session count that exceeds the authorized session count
Billing a service type that does not match the authorization on file
Billing under a provider NPI that was not specified in the authorization

Carelon Denial Codes — Reading and Resolving Common Maryland Denials

Carelon denials carry specific denial codes that indicate the reason for the denial. Reading these codes correctly is the first step in correcting and resubmitting Carelon claims. The most common Carelon denial categories for Maryland outpatient behavioral health practices are:

Authorization-related denials. These indicate the service was not authorized under an active authorization. The resolution involves determining whether retroactive authorization is available from Carelon and requesting it with the required clinical documentation, or identifying the specific authorization issue (expired, exhausted, wrong service type, wrong provider) and correcting it before any sessions billed after the identified issue date are resubmitted.

Provider enrollment denials. These indicate the rendering provider is not enrolled with Carelon or that the NPI on the claim does not match Carelon’s enrollment records. The resolution involves confirming Carelon enrollment status for the rendering provider and correcting any enrollment discrepancies.

Eligibility denials. These indicate the patient was not enrolled in Maryland Medicaid behavioral health coverage on the date of service. The resolution involves confirming the patient’s coverage status at the date of service and determining whether coverage was in effect under a different plan or program.

ICD-10 and coding denials. These indicate a coding issue with the claim, often related to diagnosis code specificity or service code mismatch with the authorization.

Carelon Claims Submission Requirements

Claims for Maryland Medicaid behavioral health services submitted to Carelon require:

The correct service codes for the service type rendered
ICD-10 diagnosis codes at the required level of specificity for the F chapter codes applicable to the patient’s diagnosis
The rendering provider’s NPI as registered with Carelon
The Carelon authorization number corresponding to the service being billed
Submission through Carelon’s claims system rather than the general Maryland Medicaid claims pathway

Carelon Billing for Specific Provider Types in Maryland

Different Maryland behavioral health provider credential types interact with Carelon in specific ways. LCPCs, LCSW-Cs, psychologists, psychiatric NPs, and psychiatrists each have their own Carelon credentialing requirements and service code eligibility. The credential type of the rendering provider affects which service codes are billable under their Carelon registration, which is a billing consideration that must be confirmed during the provider’s initial Carelon enrollment rather than discovered through a denial on a billed claim.
