2024 ICD-10-CM Diagnosis Code T38.995A

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Estrogen antagonist adverse reaction
• Octreotide adverse reaction
• Trilostane adverse reaction

Clinical Information

• Octreotide

  a potent, long-acting synthetic somatostatin octapeptide analog that inhibits secretion of growth hormone and is used to treat hormone-secreting tumors; diabetes mellitus; hypotension, orthostatic; hyperinsulinism; hypergastrinemia; and small bowel fistula.

• Receptors, Somatostatin

  cell surface proteins that bind somatostatin and trigger intracellular changes which influence the behavior of cells. somatostatin is a hypothalamic hormone, a pancreatic hormone, and a central and peripheral neurotransmitter. activated somatostatin receptors on pituitary cells inhibit the release of growth hormone; those on endocrine and gastrointestinal cells regulate the absorption and utilization of nutrients; and those on neurons mediate somatostatin's role as a neurotransmitter.

• Somatostatin

  a 14-amino acid peptide named for its ability to inhibit pituitary growth hormone release, also called somatotropin release-inhibiting factor. it is expressed in the central and peripheral nervous systems, the gut, and other organs. srif can also inhibit the release of thyroid-stimulating hormone; prolactin; insulin; and glucagon besides acting as a neurotransmitter and neuromodulator. in a number of species including humans, there is an additional form of somatostatin, srif-28 with a 14-amino acid extension at the n-terminal.

• Somatostatin-28

  a 28-amino acid peptide with the same biological activities of somatostatin-14 but with a 14-amino acid extension at the n-terminal. srif-28 is the major form of somatostatin in the gastrointestinal tract.

• Somatostatinoma

  a somatostatin-secreting tumor derived from the pancreatic delta cells (somatostatin-secreting cells). it is also found in the intestine. somatostatinomas are associated with diabetes mellitus; cholelithiasis; steatorrhea; and hypochlorhydria. the majority of somatostatinomas have the potential for metastasis.

• Somatostatin-Secreting Cells

  endocrine cells found throughout the gastrointestinal tract and in islets of the pancreas. d cells secrete somatostatin that acts in both an endocrine and paracrine manner. somatostatin acts on a variety of tissues including the pituitary gland; gastrointestinal tract; pancreas; and kidney by inhibiting the release of hormones, such as growth hormone; gastrin; insulin; and renin.

Coding Guidelines

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 aplicable episode of care:

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

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

• Unacceptable principal diagnosis - 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.

Convert T38.995A to ICD-9-CM

• ICD-9-CM Code: 995.29 - Adv eff med/biol NEC/NOS
  Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.
• ICD-9-CM Code: E932.9 - Adv eff hormones NEC/NOS
  Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.

Table of Drugs and Chemicals

The parent code T38.995 of the current diagnosis code is referenced in the Table of Drugs and Chemicals, this table contains a classification of drugs, industrial solvents, corrosive gases, noxious plants, pesticides, and other toxic agents.

According to ICD-10-CM coding guidelines it is advised to do not code directly from the Table of Drugs and Chemicals, instead always refer back to the Tabular List when doing the initial coding. Each substance in the table is assigned a code according to the poisoning classification and external causes of adverse effects. It is important to use as many codes as necessary to specify all reported drugs, medicinal or chemical substances. If the same diagnosis code describes the causative agent for more than one adverse reaction, poisoning, toxic effect or underdosing, utilize the code only once.

Filter table of drugs and chemicals:

Substance	Poisoning Accidental (unintentional)	Poisoning Accidental (self-harm)	Poisoning Assault	Poisoning Undetermined	Adverse effect	Underdosing
Octreotide	T38.991	T38.992	T38.993	T38.994	T38.995	T38.996
Somatostatin	T38.991	T38.992	T38.993	T38.994	T38.995	T38.996
Trilostane	T38.991	T38.992	T38.993	T38.994	T38.995	T38.996

Patient Education

Drug Reactions

Most of the time, medicines make our lives better. They reduce aches and pains, fight infections, and control problems such as high blood pressure or diabetes. But medicines can also cause unwanted reactions, such as drug interactions, side effects, and allergies.

What is a drug interaction?

A drug interaction is a change in the way a drug acts in the body when taken with certain other drugs, foods, or supplements or when taken while you have certain medical conditions. Examples include:

• Two drugs, such as aspirin and blood thinners
• Drugs and food, such as statins and grapefruit
• Drugs and supplements, such as gingko and blood thinners
• Drugs and medical conditions, such as aspirin and peptic ulcers

Interactions could cause a drug to be more or less effective, cause side effects, or change the way one or both drugs work.

What are side effects?

Side effects are unwanted, usually unpleasant, effects caused by medicines. Most are mild, such as a stomachache, dry mouth, or drowsiness, and go away after you stop taking the medicine. Others can be more serious. Sometimes a drug can interact with a disease that you have and cause a side effect. For example, if you have a heart condition, certain decongestants can cause you to have a rapid heartbeat.

What are drug allergies?

Drug allergies are another type of reaction. They can range from mild to life-threatening. Skin reactions, such as hives and rashes, are the most common type. Anaphylaxis, a serious allergic reaction, is less common.

How can I stay safe when taking medicines?

When you start a new prescription or over-the-counter medicine, make sure you understand how to take it correctly. Know which other medicines, foods, and supplements you need to avoid. Always talk to your health care provider or pharmacist if you have questions about your medicines.
