Once you have purchased your coding clinic subscription, you may access the purchase code by visiting My Account --> My Purchases. The code will appear under the Coding Clinic Licenses section.  The purchase code is good for however many seats you may have purchased. (For example, if you purchased ten extra seats, the code may be used 10 times.) Please share this code with your colleagues, who will then redeem it in the purchase code field on their My Subscription page. Note that a user account on the website is required. 

If you have been given a purchase code to redeem a Coding Clinic Subscription, you may redeem the code by visiting My Account --> My Subscriptions. Towards the bottom of the screen, you will see a box for you to enter your code. Once the code has been processed the Coding Clinic to which you have access will appear under My Library.

  • Inquiries from physician providers related to CPT-4. These questions will be referred to the American Medical Association (AMA).
  • Questions related to HCPCS level II codes except for A-codes, for ambulance services and radiopharmaceuticals, C-codes, G-codes, J-codes and Q-codes other than Q0136 through Q0181.

These codes do not apply to hospital or physician providers.

The AHA Central Office will not respond to the following ICD-10-PCS coding questions:

  • We regret that the AHA Central Office clearinghouse is not able to support requests for ICD-10-PCS coding advice related to outpatient procedures.  Such requests for coding advice will be returned unanswered. However, we are happy to assist you with HCPCS coding questions for outpatient procedures. The ICD-10-PCS code set was not designed to support the coding of most services that are performed by providers in the outpatient setting. The Health Insurance Portability and Accountability Act (HIPAA) Administrative Simplification Modifications to Medical Data Code Set Standards (published in the Federal Register, Vol. 74, No. 11, pp. 3328-3362, January 16, 2009) adopted ICD–10–PCS for inpatient hospital procedure coding only.

The AHA Central Office will not respond to the following types of questions for ICD-9-CM, ICD-10-CM/PCS or HCPCS:

  • Questions related to payment or coverage issues
  • Questions related to the interpretation of medical record documentation, such as identifying the principal diagnosis—unless it relates to the application of specific coding guidelines or specific previously published coding advice
  • Questions related to DRG assignment or DRG shifts from ICD-9-CM to ICD-10-CM/PCS
  • Questions related to missing or incomplete documentation or validation of what is appropriate documentation (paper or electronic)
  • Questions related to clinical issues or clinical criteria for diagnoses or procedures
  • Questions related to mediating differences of opinion between providers and auditors or payers or any other third party reviewers—unless it relates to the application of specific coding guidelines or specific previously published coding advice
  • Requests for the Central Office to code the entire medical record or operative report or to validate code assignment.
  • Questions or recommendations related to ICD-10-CM Index or Tabular List problems or conflicting instructions. Such questions should be directed to the Centers for Disease Control and Prevention, National Center for Health Statistics at
  • Questions or recommendations regarding ICD-10-PCS Index entries, ICD-10-PCS device definitions, ICD-10-PCS Reference manual or the General Equivalence Mappings (GEMS) should be sent to the Centers for Medicare & Medicaid Services (CMS) at
  • Questions related to coding data elements such as etiological diagnoses or comorbidities on the Inpatient Rehabilitation Facility-Patient Assessment Instrument (IRF-PAI) or elements on the OASIS data set
  • For ICD-10-CM/PCS only: Questions without supporting medical record documentation

The AHA Central Office was created through a written Memorandum of Understanding between the American Hospital Association (AHA) and the National Center for Health Statistics (NCHS) in 1963 to:

  • Serve as the U.S. clearinghouse for issues related to the use of ICD-9-CM before 2012 and ICD-10-CM and ICD-10-PCS currently. 
  • Work with NCHS and the Centers for Medicare and Medicaid Services (CMS) to maintain the integrity of the classification system
  • Recommend revisions and modifications to the current and future revisions of the ICD
  • Develop educational material and programs on ICD-10-CM and ICD-10-PCS

In August 2005, CMS and AHA entered into an agreement for the establishment of an AHA clearinghouse for issues related to the use of certain HCPCS codes. Under this agreement, responsibilities of the AHA Central Office includes providing advice on the following:

  • Level I HCPCS (CPT-4 codes) for hospital providers.
  • Certain Level II HCPCS codes.
