T38.7X5A is a billable ICD-10-CM diagnosis code for adverse effect of androgens and anabolic congeners, initial encounter. The 7th character A marks it as an initial encounter code, used while the patient is receiving active treatment. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 917 through 918. The code is not accepted as a principal diagnosis by the Medicare Code Editor. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Adverse effects of drugs and medicaments, initial encounter.

Medicare Code Editor checks that affect claim validity for T38.7X5A.

There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Coding GuidelinesGuidance

When coding an adverse effect of a drug that has been correctly prescribed and properly administered, assign the appropriate code for the nature of the adverse effect followed by the appropriate code for the adverse effect of the drug.

The appropriate 7th character is to be added to each code from block Poisoning by, adverse effect of and underdosing of hormones and their synthetic substitutes and antagonists, not elsewhere classified (T38). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

  • Glucuronosyltransferase

    a family of enzymes accepting a wide range of substrates, including phenols, alcohols, amines, and fatty acids. they function as drug-metabolizing enzymes that catalyze the conjugation of udpglucuronic acid to a variety of endogenous and exogenous compounds. ec 2.4.1.17.

Questions About T38.7X5AOverview

Is T38.7X5A (Adverse effect of androgens and anabolic congeners) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report adverse effect of androgens and anabolic congeners, initial encounter on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What does the 7th character A in T38.7X5A mean?

The final character A marks the initial encounter: use it while the patient is receiving active treatment for adverse effect of androgens and anabolic congeners, such as an emergency visit or first evaluation.

What MS-DRG does T38.7X5A group to?

On inpatient claims, adverse effect of androgens and anabolic congeners, initial encounter maps to MS-DRG 917, 918, with relative weights from 0.8571 to 1.5684 depending on complications. Higher weights mean higher Medicare reimbursement.

Can T38.7X5A be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because adverse effect of androgens and anabolic congeners, initial encounter describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

What is the ICD-9 equivalent of T38.7X5A?

Under the General Equivalence Mappings, adverse effect of androgens and anabolic congeners, initial encounter converts to ICD-9-CM 995.29 (adv eff med/biol NEC/NOS) and E932.1 (adv eff androgens). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
